Trek alpha sizing for MTB – what is it?

The old-school approach of measuring the frame size of Trek bikes is a thing of the past. With newer inventions and modern bike geometry, alpha sizing is used in place of numeric sizing on Trek mountain bikes.

Why is alpha sizing important?

1. Easier approach

Instead of using size numbers like 19.5, the sizes can be classified into S, M, ML, L, XL, and XXL. So, someone with a 17.5 size can go for the medium and a 19.5 is a large size. You don’t have to keep a tab on numbers; instead, the alphabet makes it easier.

2. Measurement based on reach

In earlier times the frame size measurement of Trek bikes was solely based on seat tube length. Things have changed, and modern mountain bike geometry focuses more on reach as of now. Hence, alpha sizing measures what matters and is a more simplified way of measuring bike size.

Trek sizing – virtual vs actual

This can puzzle you a bit as they both are somewhat similar yet there is a subtle difference. Actual size can be termed as the overall length of the seat tube from the center of the bottom bracket to the center of the top tube intersection with the centerline of the seat tube.

On the other hand, virtual sizing is the overall length of the seat tube ranging from the center of the bottom bracket to the mid-point of the imaginary horizontal top tube in which it connects with the seat tube.

If I had to give you an example, a bike might have a virtual size of 18.5 and an actual size of 17.5. This means that the bike size feels like 18.5, but in actual sense, the frame size is 17.5. It doesn’t make much of a difference as it is there only to let you know what it is (actual size) and what it looks like in size (virtual size).

People also ask

Trek 17.5 frame size – what does it mean.

A 17.5 frame size is considered an M size (Medium) in terms of alpha sizing. Any individual who is 161-172 cm or a height of 5’3.4”-5’7.7” . If you are within this height range, going for a medium size shall be the right choice.

Trek medium frame size is for what height?

A medium size frame size (17.5) is ideal for a person with a height between 5’3.4”-5’7.7 ”. In centimeters, it is ideal for those around 161 to 172 cm in height.

Trek 24-inch bike is for what age?

When it comes to children, their bikes are measured in terms of wheel size instead of the standard frame size. These kid’s bikes have a size range between 12-26 inches, depending upon the height of the kid.

As far as a 24-inch wheel size is concerned, any kid between the ages of 8-11 can go for a fun ride with it. Some of the popular 24-inch bike models are Trek Roscoe 25, Wahoo 24, Trek Precaliber 24 , etc.

Trek 26-inch bike is for what height?

A 26-inch wheel-size bike is for kids with a height of 4’9”-5’3” (146-160 cm) . Wahoo 26 is a prime example of a bike in this category.

Trek 20-inch bike is for what age?

Trek 20-inch bikes are for children between 5 to 8 years of age. Additionally, if they are within the height of 3’9”-4’6” , it should be suitable for them.

Are Trek bikes good?

Trek bikes are considered to be extremely good and solid in build. It is known to be the number 1 performance bike brand all over the globe. Having its humble beginning in the year 1976 in Waterloo, Wisconsin, it has turned into the largest bicycle manufacturer all over the world. With an array of bikes ranging from, mountain, road, electric, and kids bikes, there is a lot to choose from a mammoth list.

How much is a used Trek bike worth?

It depends on a lot of factors in terms of how old the bike is, the year of production, which model, and a lot more. However, it can be within $1000-10,000 (depending on the model and other factors) .

Where are Trek bikes made?

The majority of their bikes are manufactured in Taiwan, China, Netherlands, and Germany too.

Why are Trek bikes so expensive?

Usually, the bike brand prefers top-tier components, suspensions, and frames that are ahead of its competitors. This results in additional costs that can be seen in the price tag and also many top-end Trek bikes are custom-made with less production, leading to being more expensive.

Trek bikes are a class apart in many ways with a range of bikes on offer for its fans across the world. Choosing the right size for you can be tricky, but this is where the Trek frame size chart comes to the rescue.

Trek as a bicycle brand might be on the costly side, but they punch above its weight to provide top-class bikes for the masses. I am always someone who roots for quality, and Trek provides what I need.

One comment

Thanks for your informative post. I really like the Trek alpha sizing for MTB because Trek frame sizes use alpha sizing rather than the usual inches or centimeters (cm), and they usually have a certain range of measurements.

Road Bike Size Chart: A Simple (But Complete) Guide

“Bike Pursuits is reader-friendly. We may earn a small commission when you buy through our links. Read More!

Many road bikes typically come in 2 styles that include sportive road bikes (that have short top tubes & high front ends for more comfort) and racing road bikes (these are long in their top tubes & low for fast riding at the front). Nowadays, there has been an increase in cyclocross bikes.

These are typically for casual off-road drives. Hence, it has led to the invention of new adventure road bikes. They are drop-bar and lightweight bikes for a mixture of terrains, trails, and roads. For detailed information on the  road bikes size chart,  keep reading this article.

Road Bike Sizing Guide for men, women & Kids

You need to select an appropriate size of a road bike frame for a new bike that does make all the difference. It is so as when the bike fit is ideal, then you would feel more comfortable while riding. The handling of your road bike would be simpler, and you would enjoy the riding experience more.

In this road bike size guide, we would tell you how simple it’s to look for the right bike size by simply using the following bike size charts (men, women, and kids) for the particular road bike that you are quite interested in.

Road Bike Size Chart for Men

Road Bike Size Chart for Women

bicycle riders, riding, cycling

Every road bike might look quite similar. However, in case you try out some male’s bike, then you would quickly come to know that it isn’t quite as comfy as you will like. Hence, a good way to purchase a road bike is to see female bike sizes for several types of road bikes.

Surely, this is not a thumb rule, but it provides you a clear notion of what you’ll be looking for. When your road bicycle is delivered, then you might make some necessary adjustments on the handlebars and saddle and all other parts for making sure that you’ll get a perfect ride experience every time.

Road Bike Size Chart for Kids

bike, children, cycling

You can look at following road bike sizing chart for kids to see how kids’ road bikes are defined and measured. You will get a clear idea about what you are actually looking for while shopping for some specific road bike. A crucial thing to keep in mind is that you can measure children’s road bikes by using the tire diameter (outside). It’s just opposite to adult road bikes, whose measurement refers to the bike’s frame size.

One real challenge in picking a child’s road bike is to exactly knowing that the child would outgrow this not long after you buy a bike. Hence, you are facing a serious dilemma. Also, do you purchase a good road bike that would likely be a bit smaller? And, do you buy some big-box clunker that is a temporary and cheap solution? In this case, you are anticipating that a road bike does not fall apart at all or otherwise is such a bad choice which it does turn your child off to riding altogether.

This is a basic question without a simple answer, but probably a couple of other choices that you might explore to assist yourself out. First of all, do you’ve other children, younger or older, that you might give this road bike to them? If this is the case, then it does make the question even simpler about whether or not to consume money on some decent road bicycle.

How about your extended family members, cousins & the like? Also, are there any families in your neighborhood with children that you might set up a kind of road bicycle exchange with?

One more good idea is to resale the road bike. In case you have some connections with the other cycling lovers who have children, they are even more likely to come to know & appreciate the true value of a nice road bike. Offering this for sale, such as you will an adult’s road bike, is a great way to retake some of the investment.

Lastly, certain road bike shops & online retailers (that include Performance Bike) typically offer you some programs for buying children’s road bikes.  The main premise is that if you purchase a child’s road bike, you will get either guaranteed trade-in value on your old road bike in case it’s outgrown or some straight out discount offers on the future road bikes. This is quite advantageous because the child continues moving through the road bikes into the large sizes.

What is important to look out for when choosing the right road bike size?

Seeking the proper road bike size is not difficult anymore. All you have to do is simply measure your own height. Now, look at the above road bike sizing chart. You may also want the measurement of your inside leg as different bike brands such as Giant typically use this measurement and height in their particular bike sizing charts.

We have also teamed up along with different professionals to inform you how simple it’s to select the perfect size bike if you are going to buy it online. Also, we offer some useful tips about how to select the best size road bike for yourself when you’re in-between sizes.

Sizes for Different Types of Bikes

The mountain bike sizes and road bike sizes are a bit different. Also, the units that are there in different bike sizes differ, relying on the brand and type. The road bike size charts are generally in centimeters, whilst the mountain bike size charts are available in inches . By luck, our road bike size chart does take away the guesswork because it also tells you road bike frame sizes in inches as well as centimeters. It would be very helpful for you while buying a road bike.

There are a lot of bike manufacturers who typically quote their road bike sizes such as L, M, S, or large, medium or small, etc. on a few or all of their products. Children’s road bike sizes generally depend on the wheel size. Many MTB sizing guides would use inches whilst you may find a road bike size in centimeters. So, it is good for you to know both of them

Sizing in Store

In case you have a road bike just in front of you, just stand straight at the center of the top tube. Also, there must be clearance between the bike and you that is 2 to 4-inches for the mountain bikes & 1 to 2-inches for the road bikes. Are you worried about a seat height sitting properly? Stop worrying. Once you have found the exact size for your road bike from a trial test drive, you might easily adjust your bike to fit properly.

Sizing Online

In case you do not have a road bike just in front of you, then the most crucial measurement for you to know is the inseam. An inseam measure is typically the length from the crotch down to the feet. When you‘ve got this measurement, you can easily use your chart as a buying guide for the best road bike size.

How proper must a road bike fit look like?

As you have selected a right frame bike size; however, that does not mean your road bike fits properly. There is a lot more you should – can – do in order to tune the machine to your body. Why this?

  • To go further and faster
  • To avoid any type of injury
  • For greater pleasure and comfort

The following are the top five techniques to keep your road bicycle setup easy.

1. Adjust the Reach

If you stretch from a bike’s saddle to its bars, it determines the riding position. Plus, your spine must lean at about 45 degrees so you would be able to reach all parts of your bike’s bars conveniently. You should bend your elbows slightly. The excessive stretch is also very common, particularly for females, who usually have relatively short torsos as compared to males.

You might reset the reach along with long or short bars or stems with a totally different reach. Like, for instance, the aluminum OS-99 CSI, ultralight carbon, and aluminum SL-K provide stem along with the +/- 6º rise. It is there in all sizes that are from 70mm up to 140mm, which allows different adjustments. Amongst FSA’s different stems is an SL-K. It contains high-grade aluminum & weighs only141g in a hundred mm length.

2. Adjust the Bar Angle

You can easily neglect the old suggestion regarding drops parallel to the surface – it’d almost surely put so much weight on the hands. You can simply rotate your bars until you get a nice bend in the wrist. Plus, the hoods must not pull the thumbs, such as wishbones.

Your height is a major key. In case you are racing, you will need the bar a bit lower than your saddle. However, otherwise higher or even level is just fine. Its major defining factor is a great level of comfort.

In addition, carbon fiber also damps the vibration for more long-distance performance. On the other hand, a shallow drop, just like a 125mm K-Force Compact, is comfortable as well.

In case you are racing, then you still should not worry about as the 150mm-drop K-Force New Ergo bar offers large-radius curves & a flat, wide top to decrease your fatigue.

3. Adjust the Saddle

As you know, seat height is very much crucial. Your knees must bend a bit at complete extension. You can also adjust via raising your saddle until the leg is completely straight with the heel on your pedal. In case your hips are rocking, then your saddle must be quite high.

Along with the level of pedals, the forward kneecap must sit properly above the road bike’s pedal axle. The laser pointer or plumb bob does assist here a lot. It is not a strict law, though: as you might also reset it to fine-tune your weight on the hands. Pressure must not be very much, but a little.

Lastly, the ‘right’ angle does not put much pressure on the center or front of the pelvis. You need to try to avoid the forward tilt of above some degrees, as it puts a huge weight on the wrists, which is not good at all. You must have a good and durable Seatpost for this. For example, lightweight SL-K posts give you incredibly great adjustments along with the fatigue-decreasing compliance of carbon too.

4. Adjust the Cleats and Pedals

Pressure hot spots typically cut circulation, whilst wrong angles put stress on your legs and knees. These things aren’t good at all for you! If clipped in, balls of your feet must be over your pedal axle, or a tad ahead of the pedal axle. In case you are straining your Achilles tendons or calves, reset your cleat towards your heel. When the arches are sore, then you need to move this towards your toe.

You should look down carefully when pedaling your road bike; the knee must be over the foot. You can easily adjust your cleat side to side; hence the feet are neither inside nor outside your knees. The cleats must mimic the toe-out/in an angle of the feet – and keep this in mind that they may not be similar on each side.

5. Check the Frame

When you are still trying hard to get a well-balanced position, then you might want to think again about the frame size of your road bike after all. The length of the top tube might just be not correct. As a casual guide, we will expect you to see:

  • 160centementer-169centemeter (5feet 3inches to 5feet 6inches) bikers on 52- 53centemeter frames
  • 171centemeter-181centemeter (5feet 8inches to 5feet 11inches) bikers on 54- 56centemeter frames
  • 183centemeter-193centemeter (6feet to 6feet 4inches) bikers on 56-58centemeter frames

Combining the above 5 tips, you must get the maximum road bike fit along with the advantages of cycling longer and faster in better ease, and avoiding any chance of injury.

Invest in a Road Bike Fit

Selecting a professional road bike fit before buying might make a great difference. That is why Missy Erickson, who is a fit specialist and owner at ERO Sports, suggests that the Pre-Purchase Bike Fit for every athlete. “This does not matter when you are purchasing a new road bike from some bike shop, ordering your road bike online, or getting off Craigslist,” she said.

“Knowing about every fit dimension & having a fit expert assist walk one through the whole process and not only makes sure that you’re getting the proper size but your road bicycle also for some specific requirements.”

The road bike fit would also offer all your detailed measurements. Like, for beginner athletes and cyclists, it might be very helpful. Erickson says, “Investing in the bike fit makes sure that you are about to have the right bike. Plus, you will also be going to set up your bike perfectly.

It would ultimately avoid any kind of discomfort, injury, and pain that would make roadside cycling more enjoyable as compared to this already is”.

What if I got my road bike size wrong?

If this happens, you should immediately tell your merchant, who will easily exchange that road bike. In case you do not need to do this, then you might do the following important things:

  • purchase a shorter or longer stem. This would change the position of your body
  • move the saddle backward or forward
  • to get a long seat post

You should give it some time to get the feeling right. As I remember that time when I bought my very first 29er road bike. This felt just like a huge ship & seemed too much tough to ride that in the forest or narrow trails.

However, I have become so much familiar with my bike after some time and could ride with full skill and comfort that while I sit on the 26″ road bike, it does seem so ridiculous how small it’s.

Road Bike Sizing Calculator

The road bikes come with thinner tires as well as light frames. They are specially made for riding on paved and smooth surfaces that include roads, paths, and streets. A few of them might even handle gravel roads or dirt. There are so many different types of road bikes. The road bikes are generally used for commuting, racing, and touring.

Whilst styles differ, the main approach to road bike sizing does remain the same that is using the rider’s leg length and height to determine proper frame size. There is a road bike calculator that recommends the road bike frame size, depending on the measurements that you take. In case you do not know about your leg length, then you would get a large range of different frame sizes in order to try them out.

Do you have an Appropriate Ape Index?

You must know when you need a short or long reach. It does mean that you want to look for your “ape index” (that is the arm span as compared to the height).

  • When you get the positive ape index (that is your height is smaller than the arm span), then you need a longer reach & you must also opt for the bigger of the sizes.
  • When you get the negative ape index (that is the arm span is smaller than the height), then you need a shorter reach & you must also go for the shorter of the sizes.

Try Before You Purchase

It is much overused and obvious suggestion out there. However, it is true: Seeing the bike for yourself in person, trying that out, & having a feel for it’s usually the perfect way to come to know whether it is suitable for you or not.

Most bike shops and bicycle brands give demo events or days for allowing clients to test road bikes. This also assists to ask a few important questions and directly speak to expert staff members. Also, as an additional bonus, the customer avoids some potential damage like from shipping. You will not need to assemble it yourself.

Getting the exact size of your road bike is quite significant, and if this is your very first road bike, then you must pay more attention.

The exact sized road bike would be more efficient, quite comfortable, and great fun for you to ride. You should know very well about your  road bike size chart  just before you purchase it. It would surely make the entire process easier.

By doing so, you will be able to set up for successful bike rides right from the very beginning. Quite often, however, there’re some other ways as well to know whether your setup is right or not like a poor fit. Happy Riding!

Bike Size Chart: How to Choose the Right Bike Size? (GUIDE + Calculator)

Profile picture of Petr Minarik - the founder of cyclistshub.com

This guide will show you how to choose the right bike size using bike size charts and other methods. It covers the most popular bike types (hybrid, mountain, and road bikes).

You can use an interactive calculator that recommends a bike size based on your inseam length and bike type. Alternatively, you can choose the bike size based on one of the three methods explained below.

Correct frame size is important to avoid discomfort when riding, injuries, or returning a brand new bike due to incorrect size.

Be sure also to check out the FAQ section , where you’ll find the answers to common questions like:

  • What frame size do I need if I’m in between sizes?
  • Why is the correct bike size important?
  • What do you do if your bike is the wrong size?

Let’s dive in!

Bike Size Calculator

DISCLAIMER: Please remember that the calculator does not consider your height, which may affect your bike size.

What Bike Size Do I Need?

To determine which bike size you need, use one of the following methods, sorted from the simplest to the most complex. Remember that simpler methods are less precise, while more complex methods offer greater accuracy.

Method #1: Bike Size Based on Your Height (The Easiest Method)

This is the easiest and quickest method to select a bike size. All you have to do is compare your height with the general bike sizing chart below .

However, this method doesn’t consider the type of bike, so it may not be as accurate as the methods below. As a result, the bicycle may not fit you perfectly.

Method #2: Bike Size Based on Your Inseam Length and Bike Size Chart

This is probably the best bike sizing method for most people. It is based on measuring your inseam length at home and comparing it with a bike size chart .

IMPORTANT NOTE : The inseam length for choosing a bike size is measured differently from that used for buying pants. Learn more

Once you measure the inseam length, use it to select the bike size. Most bicycle manufacturers use seat tube length in their bike size charts and other details, including the standover height.

The standover height is the distance from the ground to the top of the top tube.

An illustration of a bike size based on the seat tube length and the standover height

If your inseam length is shorter than the standover height, the bike is too big for you.

The clearance, which is the difference between your inseam length and the standover height, should be around 1 to 2 inches.

This clearance is essential to prevent injuries caused by sudden or emergency stops.

Hybrid Bike Size Chart

Depending on the manufacturer, hybrid bikes usually come in descriptive sizes (XS-XL) and heights. However, you may still encounter all three types of size designations – in, cm, and descriptive sizes.

And here is a helpful infographic:

Hybrid bike size chart: Choose the hybrid bike size based on your height and inseam length. This image includes table with height and inseam ranges (in inches and centimeters) and corresponding bike size in descriptive sizes (XS-XL).

Mountain Bike Size Chart

The size of mountain bikes is typically measured in inches (13″, 19″, etc.) or descriptive sizes (XS-XL).

Generally, smaller mountain bikes usually come with 27.5″ wheels, while larger ones have 29″ wheels.

And here are the sizes in the picture:

Mountain bike size chart: Choose the mountain bike size based on your height and inseam length. This image includes table with height and inseam ranges (in inches and centimeters) and corresponding bike size in descriptive sizes (XS-XL).

Road Bike Size Chart

Road bike sizes are usually given in centimeters or descriptive sizes.

When choosing the size of your road bike, you should take extra care. Road cycling is a discipline where you spend long hours in the saddle, so selecting the right bike size is crucial.

It’s also essential to choose the right type of geometry. For instance, endurance geometry road bikes (where you sit more upright) are suitable for beginners, while aggressive (sporty/performance) geometry requires a certain amount of flexibility.

The following road bike size chart also applies to cyclocross and gravel bikes .

And again, an infographic:

Road bike size chart: Choose the road bike size based on your height and inseam length. This image includes table with height and inseam ranges (in inches and centimeters) and corresponding bike size in centimeters.

Method #3: Calculating the Bike Size

As we know from Method #2 , bike size is determined by the length of the seat tube. To effectively use this method, you must know the length of your inseam ( learn how to measure it correctly ).

To calculate the size of your next bike, use the following formulas depending on the type of bike you want to buy.

To calculate the size of your next bike, use the following formulas depending on the type of bike you want to buy. ( Source )

  • Inseam Length (cm) × 0.685 = Hybrid Bike Size (cm)
  • Inseam Length (cm) × 0.225 = MTB Bike Size (inches)
  • Inseam Length (cm) × 0.665 = Road Bike Size (cm)

1 in = 2.54 cm 1 cm = 0.39 in

After you receive the result, round it up to the nearest whole number. This will match the bike size charts above with a slight deviation.

Example of calculating the MTB Bike Size:

Your inseam length is 33 inches, and you want to buy a new mountain bike. Let’s do the math:

Convert cm to inches: 33 inches × 2.54 = 83.8 cm Calculate the bike size: 83.8 cm × 0.225 = 18.8 ≐ 19 inches

The size of your new mountain bike should be 19 inches .

Example of Calculating the Road Bike Size:

Your inseam length is 70 cm, and you want to buy a new road bike:

70 cm × 0.665 = 46.55 cm ≐ 47 cm

As you can see, your new road bike size should be 47 cm .

How to Measure the Inseam Length?

To measure your inseam length, follow these five simple steps or watch the video below:

  • Prepare a 0.75 to 1-inch (1.9-2.5cm) thick book and a tape measure.
  • Take off your shoes and stand with your back to the wall.
  • Put the book in your inseam, firmly pull it up, and hold it with your tights. Make sure the book is pressed against the wall on one side.
  • Measure the length from the top of the book to the floor.
  • Take the measurement.

NOTE : The inseam for choosing the right bike size is different (a few inches longer) from the inseam used to choose the pants’ size. Remember that inaccurate inseam length may affect the recommended bike size.

How to Measure Your Inseam for a Bicycle

Once you measure your inseam length (and eventually also your height), you can compare it with the bike size chart of the specific bike type. Based on it, you can choose the correct size.

Choosing the correct bike size is easy when you know how to do it. You can use the bike size calculator that recommends a size based on your inseam length and bike type, or try one of the three methods I explain:

  • The first method is simple but not very accurate. You only need to know your height and compare it with the universal bike size chart.
  • The second method is the most accurate. First, measure your inseam length and decide what bike type you want. Then, compare your inseam length with the hybrid, MTB, or road bike size chart, and you’ll have the right size to buy.
  • The third method requires some math but is more accurate than the first. You need to know your inseam length and use special formulas to calculate the size of your next hybrid, mountain, or road bike.

If you’re still unsure about what size bike to choose, please ask in the comments below or email me .

Choosing a Bike Size FAQ

I remember trying to choose the size for my first road bike. I asked a cycling forum for advice because I was stuck between two sizes. The forum members gave me some tips, but most were too complicated for a beginner like me. They suggested that I check the bike’s geometry, but I had no idea how to do that or compare it to my body measurements. So I asked my friend, who has been selling bikes for over 10 years at a local bike shop. He gave me the following advice: “It depends on what kind of rider you are. If you’re a recreational rider, go for a bigger frame. It’s more comfortable because you won’t have to raise the saddle as high as you would with a smaller frame. This will give you a more upright position, which is more comfortable. However, if you’re serious about cycling and want to race, a smaller frame will give you a more aerodynamic and aggressive position. Smaller frames are also more agile and lighter.”

There are several ways to choose the right size bike, but in this guide, I’ll explain three methods: 1. The first method is based on your height and a universal bike size chart. It’s the simplest but not the most accurate method. 2. The second method uses your inseam length and specific bike size charts for hybrid, mountain, and road bikes. It’s the most accurate method for most people. 3. The third method involves calculating the bike size using your inseam length and a unique coefficient that varies based on the bike type. It’s more accurate than the first method but not as accurate as the second. You can also use an interactive calculator that recommends bike size based on your inseam length. I recommend reading the entire article to better understand each method and decide which one works best for you.

Choosing the right bike size is crucial, not only for your comfort but also for preventing health problems. If your bike doesn’t fit you properly, you may experience pain in various body parts, such as your lower back, neck, and hands. ( Source ) According to Physio-pedia.com , there are four essential components of a good bike fit: correct foot position, saddle height, stem length, and handlebar position. However, remember that if your bike is two sizes too small or too big, you won’t be able to achieve a proper bike fit. Therefore, learning how to choose the correct bike size is important. You can avoid discomfort and potential health issues by selecting the right bike size. So, take the time to find the perfect fit for you.

If you have ordered a new bike the wrong size, I recommend returning it as soon as possible. Most online retailers allow returns. If you ride the wrong size bike, you risk injuring yourself (e.g., overloading certain muscles) or not being comfortable in the saddle. It also happens that even experienced cyclists ride the wrong size bike, so they often fail to adjust it to their liking.

It’s a bit complicated. The answer is mostly no, but there are some exceptions. Let me explain. Many people ask this question. But it is a wrongly asked question because bike size doesn’t depend on age. Our heights vary greatly, so a 19-inch bike may suit someone even if they’re not the “correct age” for it. The correct question is: “What height and inseam length is a 19-inch bike for?” With this information and the bike chart for the specific bike, you can determine who the bike is suitable for. Read the entire guide on choosing the right bike size for more information.

A 26-inch bike refers to a bicycle that uses 26-inch wheels. These wheels are commonly found on kids’ bikes, but some adult (mountain) bikes also use them. Nowadays, 27.5-inch and 29-inch mountain bikes are becoming more popular because they offer better comfort and speed. If you’re shorter than 5’0″ (150 cm), a 26-inch bike may be a good choice. However, if you’re taller, I recommend choosing a bike with at least 27.5-inch wheels. Check out this guide to learn more about selecting the right bike size.

What size bike should I get?

We’ve compiled an extensive guide to bike sizing that makes figuring out the right size a whole lot easier. Below you’ll find great info on how different bikes are sized and how to find the best fit for men, women, and kids. Consulting a bike shop is always the best way to get the best fit, but this article will help you get a good idea of where you sit.

How do you figure out your bike size?

Bike sizing can be a bit of a pain sometimes because there isn't always one universal system of measurement that’s the same for all types of bikes and all riders.

Depending on whether you’re looking for an adult bike, a kid’s bike, a road bike, or a mountain bike, you’ll need to find out what your frame size or wheel size is. 

We always recommend heading into your local bike shop to get the best possible fit, but you can also you the size charts and information in this guide to find the size that's best for you.

Adult bike sizing vs kid bike sizing

In a nutshell, adult bikes are sized by the frame, and kids bikes are sized by the wheel.

That means that there are two completely different measurement systems between adult and kids bikes. As children grow they’ll obviously start to fit on small adult bikes, but generally, kids 12 and younger will fit on bikes that are measured by the size of the wheels.

woman riding bike

Women’s bike sizing

While some companies offer women-specific models with designs that aim to incorporate better-fitting components, there is no substantial difference between men’s and women’s bike sizes. Both women and men can use the same adult bike size charts below to find a great fit.

To make matters a little more confusing, sizing can also vary between styles of bike or the company that makes them. For example, road bikes and mountain bikes will often use different numbers to designate sizes.

Without going into too much detail, bike size used to be determined by measuring specific parts of the bike, like the seat tube. However, over time manufacturers have decided to update their measurement system since bike geometries have changed considerably. The goal was actually to make it easier for people, but since some companies still stick with the old systems, it can be a bit puzzling.

In the sections below we have broken down a few size charts for road bikes, mountain bikes, hybrid bikes, and kids bikes. It’s important to note that there is no single bike size chart that is universal to all brands or styles. Many bike manufacturers differ slightly in their sizing, but the charts below will give you a good idea of where to start.

Road Bike Size Chart

Road bikes will often use measurements in centimeters to denote frame sizes. If you’re looking at a road bike and you don’t know what size it is, start by measuring the seat tube, as that will give you a good ballpark idea.

Shop Road Bikes

Are you in between road bike sizes on our chart and unsure which way to go? Here are some points to consider:

Size up on a road bike if:

  • you have long arms (your wingspan is larger than your height)

Size down on a road bike if:

  • if you're mostly concerned with having a bike that's lighter and stiffer (sprinters)
  • if you prefer an upright riding position

Mountain Bike Size Chart

Mountain bikes will either be measured in inches or, more likely, in a consumer-friendly Small/Medium/Large hierarchy. Newer mountain bikes can be tough to size without the help of a sticker or stamp on the frame, as geometries have changed so much in recent years that measuring tubes won’t typically give you very good insights.

Shop Mountain Bikes

When choosing the wheel size for your next mountain bike, you'll want to take your height and your preferred riding style into account. It's true that smaller riders often feel more in control on smaller wheels, but depending on your level of experience and the desired ride characteristics, that may or may not be the best way to go for your specific goals. 

If you're a beginner, go with the first option on the suggested wheel size portion of the above chart. If you're an advanced rider, you might consider the other listed option and decide which wheel size will suit your riding style best.

As a rule of thumb, larger wheels have faster top speeds and roll over obstacles easier, while smaller wheels are more maneuverable and "playful". If your trail priorities are speed and efficiency, go with a larger wheel size. If your priorities are agility and playfulness, you might really enjoy a smaller wheel size.

Trek recommends riders go with the largest wheel size they can comfortable handle. We'd add to that by saying the best way to get a feel for what's comfortable for you is to come test ride a bike!

Are you in between mountain bike sizes on our chart and unsure which way to go? Here are some points to consider:

Size up on a mountain bike if:

  • you're a more aggressive rider who appreciates a longer reach
  • you prefer stability on descents to maneuverability
  • you like to ride over and through obstacles rather than around them
  • your wing span is greater than your height
  • you are flexible and better at maneuvering your body to adjust to terrain

Size down on a mountain bike if:

  • you prefer to ride more upright
  • you riding style is more conservative than aggressive
  • you prefer maneuverability over monster truck-like plowing power
  • you are less flexible and tend to ride in a similar position

It's important to point out again that not all manufacturers use the same frame size naming conventions. Some brands prefer to "simplify" their sizing to numbers from 1 - 6 (instead of XS - XL) for example. The thing to keep in mind is that not all brands are sized the same, and it's important to look at the size charts provided by the brand you're looking at, as well as the bike's geometry chart, in order to get the best fit.

In the early days of mountain biking, we used to size MTBs by the lengths of their seat tubes, as that would give someone a pretty good idea of what the standover height for a bike would be. That worked for a while, when frame design was relatively straightforward with top tubes and geometry that were more similar to road bikes.

As mountain bike design evolved, manufacturers were able to find more capable performance with different tube lengths and angles. With longer, more sloped top tubes and dropper post-ready designs (and more variations across brands), the seat tube is no longer the best way to approximate a bike's size. This paved the way for brands to start their own sizing methods.

Hybrid Bike Size Chart

Hybrid bikes like commuters and fitness bikes are great all-arounders that are extremely versatile and often very affordable. Most hybrid bikes use a Small/Medium/Large measurement system, but you might find a few companies who still use inches as the size denotation.

Shop Hybrid Bikes

Go with the larger size if:

  • you have long arms (an arm span that's longer than your height) or long legs
  • the larger size has larger wheels and you prefer larger wheels

Go with the smaller size if:

  • you have a longer torso but an average or shorter arm span/inseam
  • you have bad hips or a bad back or other mobility issues

Kids Bike Size Chart

As we stated above, kids bikes are measured by the size of their wheels, and it’s much more straightforward than adult sizing. A 12-inch bike has 12-inch wheels, a 16-inch bike has 16-inch wheels, and so on. Here is a great general kids bike size chart to get started, but it’s always best to have your child try a bike before you buy it.

What to do if your child is in between kids bike sizes

Go for the larger size if:

  • they feel confident on the bigger size
  • they're getting into racing or biking as a sport

Go for the smaller size if:

  • they're less confident riders

It's almost always better to size up with kids bikes, but only if they can actually handle the larger size. Kids grow up fast, and as a parent you'll want to try to give them a bike that they can ride for at least a few years, not just one.

There are some exceptions, though. Go too big and they may not be able to control the bike, which is more dangerous and certainly less fun. Kids will become better riders when they're riding a bike they feel confident on.

How to check if a bike is the right size

Let’s say you’re standing in front of a bike that you’re interested in buying and you even know what size bike it is. According to all the size charts, the bike should be about right, but how do you know for sure? And what if you’re right on the line between two sizes? Read on to learn some of the most important things to consider when looking for the perfect fit.

Important:  getting the right fit on a bike is just as important as choosing the right size frame. If you're feeling unsure or experience pain when you ride, you should consider brining your bike to a shop. The Bike Shoppe can help! Explore our bike fitting services .

Standover height is essentially the distance between the top tube and the ground at the point where you stand over the bar. This is an important measurement to get right because you’ll want some space between your groin and the bar when you hop off the seat. For most bikes you’ll want an inch or more of standover room for a super comfortable fit. You can easily test this by pulling the bike up until it touches your body when you’re standing. If you can pull the wheels up an inch or more, you should have plenty of space.

After you’ve made sure you have enough standover room, you’ll want to make sure your legs have the proper amount of extension. You can adjust the seat height to get the right fit, but if you’ve jacked the seatpost up to the max and your legs are still very bent when you pedal, you might need a bigger size.

Here’s how to get proper leg extension:

On the downstroke, or when the pedal is closest to the ground, you should look to have around a 15-20° bend in your knee. Depending on the person you may prefer more or less bend, but you want to avoid having your knees come up too high when you pedal, which is uncomfortable, inefficient, and bad for your joints.

Another way to check your leg extension is to put your foot on the pedal and see if you can lower your heel below the axle of the pedal on the downstroke. If you can push your heel a little further than the axle, that’s often an optimum position in terms of efficiency and comfort.

Reach is pretty much what it sounds like. Specifically, the official reach measurement is usually the horizontal distance between the bottom bracket and the head tube. More generally, it translates to how far you have to reach to grab the handlebars.

Reach is something to consider mostly when you’re an experienced rider and you’re in between two sizes. Selecting a bike with a longer reach will feel “roomier”, more stable at speed, and generally more confident on technical terrain. A shorter reach will help the bike feel more responsive, but depending on what kind of riding you do, that may or may not be what you’re after.

What size bicycle is right for my height?  

Before you think about what size bike you are, you’ll want to decide what kind of bike you want. As we state in the article above, road bikes and mountain bikes often use a different sizing system, so figure out what style you’re looking for first, then consult the charts above.

Should your feet touch the ground on a bike?   

Ideally you should be able to touch your toes to the ground when sitting on the seat, but if you can put your feet flat on the ground it often means that your seat height is too low. If your seat is too low, your knees will be overly bent when pedaling and that can cause discomfort and joint pain, not to mention it’s not a very efficient way to ride.

If you feel more comfortable with your feet flat on the ground, check out Electra bikes. They use something called Flat Foot Technology which is a frame design where the pedals are moved forward on the frame so you can get proper leg extension while pedaling but still put your feet flat on the ground when you want to.

Do I need a 26 or 29 bike?  

26-inch wheels were the mountain bike standard in the past, but most mid and upper tier mountain bikes you’ll see on the market today use either 29-inch wheels or the slightly smaller 27.5-inch wheels. 29ers and 27.5+ bikes have faster top speeds and roll over obstacles easier than 26-inch wheels, so if you want to ride off-road, you’ll appreciate bigger tires. 26-inch wheels are often great for kids who have graduated from their 24-inch kids bike but aren’t quite big enough to use the bigger wheels found on most adult bikes.

What size bike does a ____ year old need?

What size is a 26 inch bike.

The 26 in a 26 inch bike refers to the wheel size, so that measurement isn’t always the best way to judge how big a bike is. Some youth bikes are measured by this wheel size, but more commonly you’ll find 26-inch wheels on a variety of adult frame sizes.

Shop 26-inch bikes

Is a 26 inch bike for adults? 

In short, yes! 26-inch wheels are used on adult bikes and have been for years. That being said, most modern mountain bikes have switched to 27.5” and 29” inch wheels for their superior speed, traction, and rollover power. However, 26 inch wheels are super strong and universally available, so bike tourers often use them for traveling abroad.

Trek road bikes: range, details, pricing and specifications

Cyclingnews' roundup of Trek road bikes available to buy this year

Trek road bikes you can buy today

Trek's road bike range explained.

With a history spanning some four decades, the Trek Bicycle Corporation has become one of the foremost bicycle makers in the world, and a perennial staple in our list of the best road bikes . What started out as a small steel frame-building company operating out of a carpet warehouse in Waterloo, Wisconsin, has grown enormously into a global leader of bicycle design and innovation. The Trek road bike range is based around three anagrammatic models; Domane, Madone, and Emonda - nominally the endurance, aero, and climbing bikes respectively. All are available in an array of build options, with the Domane and Emonda also available in both carbon and aluminium guises.

Trek has a history of innovating in the world of bicycle manufacture, with a particular emphasis on pioneering new materials. Bonded aluminium and carbon construction was lifted from the aerospace industry in the '80s, creating the 2000 and 2500 framesets. The lessons learned from bonded carbon were then poured into the manufacture of the brand's first full-carbon frameset, the 5000. Nowadays it has its own patented in-house carbon fibre, known as OCLV (optimum compaction low void) which is on a par with aerospace-specific alternatives

Trek continues to disrupt the industry from a manufacturing standpoint, but first and foremost it makes bikes for riders; the manufacturing innovation is only a means to an end. For some that means the very best commuter bikes , for others that means the best touring bikes , and for a lot of riders that means racing at the highest levels. It's no great surprise that Trek has become a big player in the world of gravel cycling too, and it also features on our list of the best gravel bikes . Whatever your interests in cycling, Trek has options. If you are thinking about something from the Trek road bike range, keep reading to see all the details about what's available. 

Trek Domane

Specifications, reasons to buy, reasons to avoid.

The latest model of the Trek Domane has gone through a complete makeover. The comfort-enhanced model in the Trek road bike range picks up a number of aerodynamic details, along with an all-new Isospeed decoupler design (additional flex at the steerer and seat post) and space in the frame and fork for up to 38mm of the best road bike tyres you'd care to cram in. These are changes that make the Domane an incredibly versatile road bike. The lineup is perfect for all-day comfort and the new Domane+ LT, makes our list of the best electric road bikes too.

The Domane is available in three frame types. For the budget minded, you'll want to look at the aluminium Domane AL; it's the most accessible in terms of price, and the only option for fans of a rim brake. It's entry level but it doesn't leave off the performance and adds options for racks for commuters, though it can only fit 35mm tyres rather than the 38mm max on the carbon models.

Moving up the range, the next option is the mid-range Domane SL. Stepping up to the SL means a move to 500 series OCLV carbon fibre. That opens up access to a dual IsoSpeed decoupler system, not found on the alloy version, for comfort-enhancing vibration damping. It also means space for larger tyres and storage in the downtube. If you'd like to stick with rim brakes there aren't any options for a fully built bike in the SL range but you can still get a rim brake option of the frameset.

The top-tier Domane SLR is also carbon fibre but it's a lighter 700 series OCLV. It still carries the dual IsoSpeed decoupler, but it's an upgraded adjustable version also seen on the aero focussed Madone. Like the SL, there's no fully built rim brake option available but you can still get an SLR frameset in a rim brake format.

Depending on your taste, and budget, builds are available from Claris-level at one end, through to SRAM Red eTap at the other extreme, with most options in between available.

Trek Emonda

For years, the Emonda had been the lightweight option in the Trek road bike lineup, and one of the usual suspects in our lineup of the best lightweight bikes . This is the bike to grab when you want to head to the mountains. As technology has progressed though the modern climber's bike has somewhat disappeared; brands have been slowly moving away from labelling their lightest offering as a 'climbing bike', and instead pivoting to selling it as an all-round option, for both up hill and down dale. Trek is no different in this regard, with the Emonda filling its all-rounder spot. It's no lump though, if weight is your concern.

While the Emonda is still the bike you'd want to turn to on the steep uphill segments, it's more than that now. Aero-optimisation and disc brakes take it away from a bike only for the mountains to a much more well-rounded option. In some ways it's defined more by what it isn't than what it is. It's not the all-out aero bike and it's not an endurance bike. The Emonda is the lightest of the options but it's also a bike that does a little bit of everything.

Available models for the Emonda still cover a wide range in much the same way as the Domane, with an aluminium option at one end, with a rim brake frameset option, and two tiers of carbon above it. The SL represents the middle ground with a carbon frame at a more affordable price. Then, at the top of the range, sits the SLR with a new ultralight 800 series OCLV carbon construction. There's even an SLR frameset with a more aggressive geometry available for those competing at the highest levels or fans of ultra-responsive handling. 

Trek Madone

The Madone sits at the top of the range as Trek's most purebred race bike. It's aero optimised in every way, and features among our list of the best aero road bikes too. Being the range topper means that it's the most expensive option in the Trek lineup but that has more to do with a lack of low-end options rather than it necessarily being vastly more expensive. There are only SLR and SL models available, meaning no entry level aluminium choice to be had. 

After years of aero bikes carrying a reputation for being harsh and uncomfortable, Trek went in a different direction. It was the first to market its aero bike as not just aerodynamically fast, but also fast because of its comfort, primarily thanks to the addition of the IsoSpeed decoupler system lifted from the Domane.

Of course, comfort isn't the only trick for the Madone; integrated cables feature heavily, along with fully integrated cockpits on the top end models. Even lower models, without an integrated cockpit, look to cheat the wind, with truncated aerofoil tube shapes and aerodynamically optimised disc brakes. Tyre width is however much more limited than with other models, topping out at 28mm.

Trek Speed Concept

The Trek Speed Concept is the Trek solution for triathletes who want the very best. For years the design had been stagnant but that all changed at the end of 2021. The brand new 2022 Trek Speed Concept is all new and faster than it's ever been before. Compared to the previous version, Trek claims the new bike saves a full six minutes over the Kona full Ironman race course. 

Moving away from a solely wind-tunnel focus, Trek has sought to create a bike that works as an entire system, rather than simply a lab-optimised object. The system approach means hydration and storage helps make not only the bike faster, but also the rider. There's an available between-the-arms (BTA) bottle that enhances aerodynamics by smoothing air between the arms and a clip allows you to drink without leaving the aero bars. It's also easy to refill during a race with a port on the top that accepts the nozzle of another bottle. 

While the BTA bottle is a separate purchase, the downtube bottle comes with every Speed Concept bike. Capacity is 750 ml and, like the BTA bottle, it also enhances aerodynamics; the system is 14 per cent faster when the bottle is in place. 

Outside of hydration there are two additional storage solutions onboard and included. The two bottles cover opportunities to enhance aerodynamics so the storage doesn't make the bike more aero. Instead, the bento box and the flat repair storage take advantage of the increased frame space to hide from the wind. 

The once-simple exercise of choosing a bicycle has become an appreciably complex decision owing to a plethora of new riding disciplines and technological advancements.

There are four different types of road bikes available in Trek’s current catalogue — aero, endurance, time trial, and climbing/do-it-all, each of which differs based on design and function.

As the name suggests aero road bikes are designed for speed while still retaining some form of compliance and comfort. Climbing bikes are ideal for hilly/mountainous routes and are pretty decent all-rounders. Endurance bikes offer a combination of durability and comfort while time-trial bikes are more outlandish-looking in their appearance and built for speed.

Trek offers a wide selection of specifications for each of the models in its range. Most of the brand's road frames are available in three different types of carbon, as well as aluminium and denoted by SLR (Trek's lightest OCLV carbon), SL (mid-range OCLV carbon) or AL (Aluminium).

Different geometry options are also available on certain models, with the majority featuring regular H2 geometry and some offered in the more aggressive H1 geometry, designed specifically for racing.

These charts are based upon official Trek website sizing guide for hybrid & city, MTB and road bicycles. Take the charts below as a general guide and check the sizing calculator on the Trek's website for official results.

The Trek bike size chart, taking into account both height and inseam measurements, offers cyclists a comprehensive guide to selecting the perfect bike size for their body proportions. By considering both of these factors, riders can ensure an optimal fit and maximize their comfort and performance on the bike. Height and inseam helps determine the frame size. This chart enables cyclists to find the ideal frame size, for a comfortable riding position. With the Trek bike size chart by height and inseam chart, cyclists can confidently choose a bike that suits their body measurements and enhances their cycling experience.

Most important difference in mtb frames is the frame full suspension or hardtail. Trek offers bikes from both categories and have even more mtb bike types to offer.

Trek Road Bike Sizing

Trek road bicycles are being made in four different categories, depending on the riders needs. Aero road bikes have excellent aerodynamics and they are the choice for riders who are looking for speed and performance. Lightweight road bikes are excellent climbers and all-around bicycles. Endurance road bikes are built for those riders who spend a lot of time in the saddle, their intended use is to make riders as much as comfortable as possible during the long hours of riding. Gravel road bikes are for use on gravel and dirt roads.

Hybrid, as name states, brings a mixture of a road bike and mountain bike. They tend to have narrower tires than mountain bike and usually they have a front suspension (but sometimes comes with rigid fork too). Hybrid frames falls into the specific category between road and mtb bikes. They never come with drop bar, which differs them from road bicycles. They are ok choice for commuting and excellent one for casual fitness riders.

City bikes, as their name say, are intended for urban use on paved, asphalted roads. Main use is for transport and not for recreational riding.

3 fundamentals of correct bike size - 2022 trek madone.

The following chart provides a rule of thumb approach to determine your 2021 Madone bike size based on your height. This is a simple approach to a complex situation, but it is accurate in the majority of cases. Of course, the length of your limbs is not factored into the table below and long or short limbs or torso can play a big role in determining the right bike size for you.

In addition your riding style can influence your choice; if you like a more aggressive bike, you may prefer a smaller frame; if you prefer a more upright position, you may prefer a large frame. If you are 'between sizes', give this consideration when making your selection. 

The 2021 Trek Madone is produced in sizes 50, 52, 54, 56, 58, 60, 62  

2021 Trek Madone Road Bike

2022 Trek Madone Road Bike Size / Fit Basics

Before you purchase your new road bike, you need to ensure the frame meets 3 basic size requirements: stand-over, reach, seat height. 

1. Stand-over

Stand-over is the measurement of the height of the bikes top-tube from the ground at its midpoint.

Ok, so why is it so important? Simply put, if you are travelling along on your bike and you need to stop in a hurry, you'll have to jump forward, landing on the ground, standing with your legs on each side of the top tube. Having the correct Stand-over will ensure you do not impact your groin area during this situation. 

How to test it.

When you stand-over the midpoint of the bike, with shoes on, you should be able to lift the bike up until there is a 2 cm gap between the tyres and the floor - without the frame coming in contact with your groin. 

Bike Fit Stand Over

If you are looking at the best size option based on a geometry chart, measure from inner leg to floor (with shoes on), remove 2cm and test that measurement against the bikes geometry chart. For the Trek Madone, this is measurement L in the Geometry diagram below. 

Get this one wrong, and you may be in for a world of back pain. Whether that is upper or lower back pain will depend on whether you buy, or are sold , a bike that is too big or too small for you. Buy the correct size bike and your hours of saddle time will actually strengthen your core and back, not hinder it. 

The Reach is the distance your hands project forward to comfortably rest on bars and manipulate the brakes and gears. 

Bike Fit Reach

How to test it. 

The quickest test of correct reach is to sit in the correct riding position on the bike (a trainer is great for this or if that is available, take the bike for a quick ride or balance against a wall with someone's assistance).  

Sit on the bike in a neutral position with your hands resting on the hoods (illustrated above) and your head in a natural riding position - eyes looking forward. Now look down at the front wheel hub/axel. If the position is correct the bars should block your view of the hub/axel. If you can see the hub/axel in-front of the bars, the bike is too small.  If you can see the  hub/axel behind the bars, the bike is too large. 

Stem length obviously plays a role here. However, if you are buying a bike from a store, it should be equipped with the correct size stem for the frame. Ideally, you should only have to swap stems if you have a particularly long or short torso. 

Your saddle can be moved forward or back on the 'rails' to make small adjustments to your reach outcome. If the bike is the correct size for you, you should not have to move it all the way forward or all the way back. 

3. Seat Height

Seat height impacts on comfort and performance - correct seat height optimises both. Your seat needs to allow for an efficient and powerful pedal stroke while maintaining you in a balanced, static and comfortable seated position. 

It is also important to note that your seat needs to be in the correct position to properly determine your reach (above). 

This is a simple and quick way to ensure a powerful and efficient seat height position. Sitting on your bike, rest your heal on your pedal when it is in the lowest (6 O'clock) position.

You need to check two things now and you will need another person to assist with this. Check that your leg is fully and comfortably extended. At the same time, when viewed from behind, your hips should be level. If required, adjust the seat height to achieve the ideal balance of full leg extension and level hip placement. When this is resolved, returning you foot the usual cleated cycling position should achieve the correct amount of knee bend.

One Extra! - Bar Drop

The position of the bars relative to the seat. This is the bike fit positioning that can cause a lot of trouble and one that we recommend determining over time and with the assistance of a professional bike fitter.

If you are new to cycling with average fitness and flexibility, err on the side of positioning your bars at the top of the steerer with one spacer above the stem. This will allow options to lower the bars over time as your fitness, flexibility and riding continue to evolve.

Does this position influence which size bike to purchase? That should be a secondary consideration after first determining which frame geometry is appropriate for you. If your flexibility is limited (or not what it used to be), you may be best to consider a frame with endurance geometry to ensure a higher front end and a more relaxed position on the bike.

The following chart provides a rule of thumb approach to determine your bike size based on your height. This is a simple approach to a complex situation, but it is accurate in the majority of cases. Of course, the length of your limbs is not factored into the table below and long or short limbs or torso can play a big role in determining the right bike size for you.

2021 Trek Madone Bike Size Key Measurements

If you already own a road bike and are happy with the fit. It is good to know you bike fit basics by measuring your seat height, reach, and bar drop.

Seat Height  - Your seat height is the distance from the centre of the bottom bracket to top of the saddle when running the tape parallel to the seat post. See the purple line in the diagram above.

Bar Reach   - The distance from the front tip of saddle to centre of the bars (where the stem cap contacts with the stem). Keep the tape running parallel to ground. See the green line in the diagram above. 

Bar Drop   - The handlebar drop is the distance from the centre of the bars to the centre of the hub. See the red line in the diagram above.

Once you have these recorded, you can then quickly check how your bike setup will work with the bike you are test riding, renting or just throwing a leg over in a store.

Bike Sizing Guide: What Size Trek Bike Do I Need?

Written by  Gary Johnson / Fact checked by  Henry Speciale

what size trek bike do i need

Are you looking for a bike to buy and asking yourself “what size Trek bike do I need?”

Trek bike sizing is very straightforward and varies by type.

For example, mountain bikes follow a unique method called alpha sizing that uses designations such as small, medium, or large. Using this system, a 5’3” to 5’7” tall person can use a 17.5” frame size.

On the other hand, Trek road bike sizing takes into account the inseam length.

If you want to get on the road or hit that trail with your ideal two-wheeler, check out our sizing guides below.

trek-bike-size-chart

Trek bikes are comfortable and easy to ride, making them excellent for beginners. They also come in different dimensions, so you should find one that fits you perfectly.

Whether in inches or cm, our Trek bike size chart will help you match your height with the appropriate vehicle.

trek-moutain-bike-size-chart

Unlike other brands, Trek bikes have upgraded their MTB sizing with alpha classifications to remove guesswork for customers.

You may find that your chosen model has some and not all of the sizes in this Trek MTB size chart. In that case, branch out and look for XS and XXL options if the Trek M/L frame size doesn’t fit you.

Note that the women’s bike size chart also uses the alpha sizing guide for their line of women’s mountain bikes though the height requirement is slightly different for each size.

Did You Know

The Trek Marlin 5, which is a popular trail mountain bike, uses the alpha sizing chart, but its size is not limited to XS – XXL only! Trek also offers an XXS with 26” wheels for this MTB type.

Trek has given us 4 categories when it comes to road bicycles. These include:

  • Aero – The best aerodynamics for speed and performance
  • Endurance – Provides comfort perfect for long hours of riding
  • Time Trial – Speed-focused bikes with unique designs
  • Climbing – Lightweight bikes excellent for uphill climbing

Designed to be a mixture of road and mountain bikes, Trek hybrid bicycles are best used for casual rides and commutes.

What size bike should I get? What does “size” really mean? And what is the best way to find the correct model for yourself?

There are usually FOUR different aspects that you must consider and have a good idea about.

Riding Style

trek-bike-sizing

Do you want to ride your bike for fun or use it for racing and exhibition? Regardless of your budget, it is important that you consider the type of biking you want to do. Some people prefer to ride in the city, while others prefer to cycle off-road.

Trek bikes come in various sizes depending on the vehicle’s discipline, since some frames have different geometry to provide the support their riders need.

Rider Height

trek-frame-size-chart

Most bicycle models come in different sizes for different body types so that they fit most people well.

The height of a person, when measured from head to toe, can help determine the bike size that would match them. This is because taller people have longer upper and lower extremities compared to shorter people, which means they will need different sizes of bikes in order to ride comfortably.

Inseam Length

trek-marlin-5

After careful deliberation with the above two factors, the frame size is then ultimately determined by your inseams or the distance from your crotch to the bottom of your leg.

You should take this into consideration because it will determine how much room there is between your feet and handlebars when sitting on the saddle comfortably.

Practical Use /Test Ride

trek-mountain-bike

Last but not least, once you have chosen your bicycle size and Trek model, test out the bike with at least a short ride. This will let you assess the balance and comfort of the chosen vehicle.

Whether you ride recreationally or professionally, you cannot choose blindly. First, bikes are expensive, and second, you must buy the correct product to use it for a long time.

trek-road-bike

If you’re done with our Trek frame size chart, Trek’s online website also has a unique feature that helps you select the correct frame size. You can try their bike finder, which asks for your riding style, height, and even inseams before arriving at a recommendation.

In case you haven’t noticed, there is a lot of variation in bicycle sizing, and looking for the size I need for my height was not a walk in the park.

Well, I hope our guide answered your question about what size Trek bike do I need. Should you have any more questions, send us a message.

Bike Size Charts – For Women, Men & Kids

Right size bike - bike size graph by bicycle Guider

Getting the right bike size is crucial, there’s no doubt about that.

If you ask, “ What size bike do I need? ” you’re in the right place!

When you are lucky enough to test ride a bike, then the process is quite straightforward – it feels good or it doesn’t. It’s as simple as that.

But what can you do when shopping online (bike shops, marketplace, Craigslist and so on)?

The answer is simple – use bike size charts!

We have various methods to find the right bike size based on your height and/or inseam, so let’s take a closer look at these below.

  • Method One: Bike Height Chart – The Easiest

Mountain Bike Size Chart

Road bike size chart.

  • Method Two: Calculating the bike size
  • Method Three: Bike Size Chart (Advanced):

Kids Bike Size Chart

Right saddle height (vs standover height) for kids, what if i got my bike size wrong, method one : bike height chart – the easiest.

This method requires height and provides the proper frame size measured in inches. If you need the results in centimeters, then jump to step 2.

Your height / Frame Size / Marker

  • 4’11″ – 5’3″ = 13 – 15 inches = X-Small
  • 5’3″ – 5’7″  = 15 – 16 inches = Small
  • 5’7″ – 5’11” = 16 – 17 inches = Medium
  • 6’0″ – 6’2″ = 17 – 19 inches = Large
  • 6’2″ – 6’4″  = 19 – 21 inches = X-Large
  • 6’4″ and taller  = 21+ inches = XX-Large

What size road bike should you get? Well, it’s pretty straight-forward actually.

Height / Frame Size (seat tube height) / Marker

4’10”- 5’2” = 47 cm – 48 cm = XX-Small 5’2″- 5’6” = 49 cm – 50 cm = X-Small 5’3”- 5’6” = 51 cm – 53 cm = Small 5’6”- 5’9” = 54 cm – 55 cm = Medium 5’9”- 6’0” = 56 cm – 58 cm = Large 6’0”- 6’3” = 58 cm – 60” cm = X-Large 6’3”- 6’6” = 61 cm – 63 cm = XX-Large

These two are very generic charts, so we recommend always seeking more information from brands that you’re interested in.

Method Two : Calculating the bike size

  • Take off your shoes and stand with your legs about 6″ – 8″ (15 – 20 cm) apart. Measure the height from the ground to your crotch.
  • Be sure of the type of bicycle you want: Mountain bike, city bike or road bike. You can read about the different bike types  from here .

Leg Inseam method

City bike – Leg inseam (cm) x 0,685 = Your frame size Mountain bike –  Leg inseam (cm) x 0,66 = Your frame size Road bike  – Leg inseam (cm) x 0,70 = Your frame size

(If your leg inseam is 76cm, then your right mountain bike size is 50 cm (20”), road bike 53 cm and city bike 52 cm)

Method Three : Bike Size Chart (Advanced):

Mountain bike size chart, city bike (also commuter/ hybrid bikes ) size chart, road bike size chart.

Got the right size?

Nice! And now go cycling!

* Please  note  that frame sizes from  XXS – XXL  don’t have the same meaning for every manufacturer. Those sizes (like on clothing) show current model sizes.

When it comes to kids’ bike sizes , it’s essential to explain that they work differently than adult’s bike sizes. They are based on wheel size rather than on frame size.

Let’s consider several methods all at once of how to size a bike for a kid with more certainty.

If you want to make sure to choose the right kids’ bike size, you should take into consideration  

1) Age, 2) Height, 3) Inseam, and 4) Tire Size

Seems tough ? Actually it isn’t because we gathered all of this data into our kids’ bike size chart (below)

As a result:   You can double-check the results. If satisfied, you can choose the right bike based on these results.

If you find that some numbers don’t match and you’re getting different results based on different criteria, remember that all kids are different. As they get older, the discrepancies between individuals become  even larger.

Choosing the right  saddle height is extremely important for all riders, especially for kids. If you place the saddle too low or high, your child is likely to feel a lack of control and lack of confidence.

So, let’s make it clear.

The right saddle height has a very important role . If it’s too low, you won’t have enough power in your feet. In mountain bike racing,  I have experienced  that when the saddle falls one inch down from normal, I lose about 25-50% of my force. I better stop and let the group go, then fix it and lose 15 seconds but I do  catch the group  and can even get the next group ahead. So the right saddle height plays a big role!

Right Saddle Height

The easiest way is to

  • Lean to the wall  with your elbow sitting on the bike (or let someone help you as shown on the picture)
  • Put your leg to lowest point  but parallel to the ground.
  • Move your saddle up or down until you have a nice bend  behind your knee. It should be something around 30 ° but don’t waste too much energy finding that exact angle.

Go out and ride . Does it feel good? If not, then adjust. Also, you can adjust the seat to front and rear. 

But… which brand to buy? See our Best Bike Brands

TIP: If you got the right height, mark it down with some sharp object. That’s the best size chart ever 🙂 Some bikes have centimeters marked there, then keep this in mind.

Then ask your merchant, if you can send your bike back to get the right one. If you don’t want to do that, then you can do the  following things :

  • Move your saddle to the front or rear
  • Buy a longer or shorter stem. It changes your body position
  • Buy a longer seat post

Give it time to get the feeling right. I remember when I got my first 29er  mountain bike . It felt like a ship and seemed difficult to ride in  narrow trails  of the forest. Now I start laughing when I sit on a 26″ mountain bike because it looks so tiny.

Trek Bikes Sizing Guide

Alpha size is easier to understand and enables you to find the right fit by the measurement that matters most.

Trek Mountain Bike Size

All Trek mountain bikes use alpha sizing instead of numeric sizing. Rather than labeling their bikes with size numbers like 17.5 and 19.5, Trek uses sizes like M and L.

Trek Road Bike Size

Trek mainly produces four types of road bikes. How do you know which road bike is best for you? The following is the general size for Trek road bikes in alpha size.

Trek has always been committed to improving the riding experience of every outdoor athlete. Each model of bicycle has different performance, durability, and design. Before buying your Trek bike, you should better know some tips on how to choose and the right bike size.

Bike Size

Measure Your Height

You need to be sure you’ve measured your height accurately. Stand against a wall, and use a pencil mark the wall on top of your head. Then measure from the floor to the mark.

For most people to get the right bike frame size, measuring the height will suffice. But the Ape Index will ensure you get a comfortable distance between the handlebars and your saddle.

Stand Over Height

It would be best to consider your inside leg measurement to ensure adequate standover height when choosing your bike. Standover height is the clearance between the top tube and the bottom of your crotch. We recommend a distance of 2-4 inches for mountain bikes, and for road or hybrid bikes, 1-2 inches of clearance is required. It will ensure comfort when you’re stopped and standing astride the bike.

You are here, trek bicycle plans to ‘right size’ with 10% cuts to spending.

BOULDER, Colo. (BRAIN) — Trek Bicycle president John Burke has told company leaders that he has decided to “right size” the company by 10% in response to slow sales and high inventory levels. But he says the company's overall strategy remains unchanged.

In an internal memo Burke sent to executives recently, he said details of the cuts would be announced Friday.  He said in addition to a 10% cut in spending, Trek would substantially reduce its stock keeping units (SKUs), saying Trek’s model year 2026 SKUs will be 40% lower than model year 2024. 

“These are turbulent times in our business,” Burke began in a confidential Company Update document that Burke sent internally, which BRAIN has obtained.

He went on to say the global bike market is “in chaos,” with high inventory levels at wholesale and retail levels leading to “significant and continued” discounting. He said retail sales were also below Trek forecasts, including in January and February this year. He said the company had not hit its monthly sales goals for the past 15 months. 

He said the situation left him with three options: simply hope for better days ahead, continue to make cuts around the edges, or “right size our business to the realities of the marketplace.” He said he decided to take the third route.

He said Trek would reduce overall spending by 10% with cuts to programs and positions, with decisions made on or before March 8. Trek will also simplify its product lines and reduce inventory levels; He said model year 2026 inventory will be 20% lower, measured in days in stock, than they were before the pandemic bike boom. 

However, Burke said Trek’s overall strategy has not changed and the brand’s “flywheel” is “spot on.”

BRAIN has reached out to a Trek representative for a response.
