The 7 Best Bike Speedometers Suitable for Beginner Cyclists

CyclistsHub is supported by its readers. We may receive a commission if you buy products using our links.

These are the best bike speedometers suitable for beginners and casual cyclists. Remember, speedometers only offer basic features like measuring your speed, distance, trip time, etc.

They don’t offer as sophisticated features as bike computers and are incompatible with 3rd party sensors like power meters or bicycle radars .

KEY TAKEAWAY

The best speedometer overall is the CatEye Padrone . It will provide you with all the basic metrics needed (average speed, distance, trip time, etc.). Furthermore, it’s wireless, so it’s easy to set up and use. It also stands out thanks to its availability in multiple colors and long battery life.

Below, I will also guide you through features to consider when choosing a speedometer.

What Are the Best Speedometers?

Best Design

Best Overall

Most Capable

Choosing the best speedometer depends mainly on your budget. I recommend buying a wireless speedometer for its ease of setup and cleaner look of your bike if you have more money to spend.

Most speedometers can display basic metrics like speed, distance, or ride time and will last for several months or years on one battery (or charge).

Remember, speedometers are not as sophisticated as dedicated bike computers ( learn more ).

Visit my best bike computers article if you want a head unit with intelligent features, navigation, and compatibility with additional sensors.

Skip to the comparison table…

CatEye Padrone (Best Bike Speedometer Overall)

One of the most popular bike speedometers ever…

Main Features

• Can display basic metrics
• Available in multiple colors
• Easy-to-read display
• Easy to use
• Hidden buttons
• Automatic ride pause

Technical Specs

• Type: Wireless
• Battery life: 4 months
• Battery type: CR2032
• Screen size: 2in
• Weight: 31g
• Water resistance: IPX8

I selected CatEye Padrone as the best bike speedometer because of its affordability, ease of use, and simplicity.

It’s a wireless speedometer, so it’s more expensive than wired ones. However, this slight price bump pays off in the ease of installation because you won’t have to wire the cables.

Padrone has hidden buttons at the bottom of the screen, so it has a nice minimalistic design.

It can automatically pause your ride, so when you stop, it won’t continue calculating your average speed, trip time, etc.

Furthermore, you can choose multiple colors to match your bike or cycling kit.

Its main disadvantages are its relatively short battery life compared to other speedometers (like the Velo 7 ) and its sensitivity to cell phones, which may cause inaccuracies.

CatEye Quick

Design-originality at its finest…

• Easy-to-read LCD screen
• Out-front mount included
• The speedometer is detachable
• Battery life: 12 months
• Screen size: 1.25in
• Weight: 41g

CatEye Quick caught my eye because of its design. Unlike the majority of speedometers, it’s rounded.

It’s mounted to an out-front mount, not a stem or handlebar. Furthermore, you can detach the speedometer when needed.

It has an LCD screen that is easy to read even in direct sunlight and a programmable odometer so you won’t lose your total miles (kilometers).

Simply write them down before you replace the battery and input them back. (Replacing battery deletes all data.)

Quick is simple to install (it’s wireless) and use. Its main disadvantage is that you have to have a rounded handlebar. Otherwise, you won’t be able to use its out-front mount.

Coospo BC107 (Most Capable Speedometer)

Surprisingly capable, almost bike computer-like speedometer…

• Connectivity with ANT+ and Bluetooth sensors like power meters, HR monitors, etc.
• Rechargeable battery
• CoospoRide APP for analyzing your rides
• Battery life: 28 hours
• Battery type: Rechargeable
• Screen size: 2.4in
• Connectivity: ANT+, Bluetooth
• Weight: 66g
• Water resistance: IP67

The Coospo BC107 speedometer is almost like a bike computer. Just a little simpler.

It has connectivity with ANT+ and Bluetooth sensors like power meters, HR monitors, etc. This makes it one of the market’s most capable speedometers (or budget bike computers).

It can display not only the standard metrics but also your heart rate, cadence, or power. Of course, you have to have those sensors.

What’s the catch, then? Well, its battery life is pretty short due to these features, so you will have to recharge it more often.

Unlike bike computers, it also doesn’t have in-built maps, so it can’t navigate you.

On the other hand, you can use the CoospoRide APP to analyze your rides and track your progress.

That’s great value for the money. What do you think? You can learn more about it in my Coospo BC107 review .

Sigma BC 16.16

Simple speedometer with easy-to-read screen…

• Can display all basic metrics
• Is compatible with Android smartphones via NFC chip
• Can calculate Estimated Time of Arrival
• Can calculate fuel consumption
• Type: Wired
• Battery life: 18 months
• Screen size: 1.8in
• Connectivity:
• Weight: 25g

Sigma BC 16.16 has one feature that very few speedometers do. It’s called the Estimated Time of Arrival.

It can calculate how long it will take you to reach your preset distance based on your speed.

So, you can use this feature, for example, when commuting to or from work or other points of interest.

BC 16.16 can also show you how much you save on fuel by riding a bike. This feature can motivate you to ride more. Of course, you can set your car’s fuel consumption in the settings.

The main disadvantage of this speedometer is that it’s wired. So, it will take you a little longer to set it up because of the wired speed sensor.

By the way, the Sigma BC 16.16 STS is wireless but more expensive.

Bike speedometer in a stopwatch body…

• Can store up to 30 rides
• Battery life: 8 hours
• Screen size: 1.7in
• Weight: 49g
• Water resistance: IPX6

Meilan M3 is an affordable wireless speedometer that provides basic ride data.

It’s available in multiple colors in a stopwatch-like body. Maybe it will awaken nostalgia from your school days.

Its internal memory can store up to 30 activities, so you can check your ride history and progress.

The biggest M3’s disadvantage is the short 8-hour battery life. On the other hand, you can recharge the battery and don’t have to replace it (which brings additional costs).

iGPSPORT 50S

Bike computer-like speedometer for an affordable price…

• Protective screen include
• Does not support power meters
• iGPSPORT APP for analyzing your rides
• Battery life: 40 hours
• Screen size: 2.2in
• Connectivity: ANT+ and Bluetooth
• Weight: 80g
• Water resistance: IPX7

iGPSPORT 50s is like Coospo BC107 but less polished. These two speedometers are direct competitors, and it’s up to you which one you like more.

Both offer more or less the same features – including connectivity, ease of use, data fields, etc. However, iGSPORT 50s does not support power meters.

On the other hand, it has an edge in battery life, and the packing also includes a screen protector.

You can also pair it with the iGPSPORT APP and analyze your rides.

CatEye Velo 7

Battery life champ…

• Looong battery life
• Battery life: 3 years
• Screen size: 1.5in
• Weight: 28g

If you are looking for a bike speedometer that you will attach to a bike and leave it there without needing to replace a battery for a few years, this one is the one to buy.

It has a battery life of up to 3 years. That’s probably the longest battery life of all speedometers on the market.

Naturally, this speedometer is very simple and only measures basic metrics like speed, distance, time, etc.

Of course, it can automatically pause measuring once you stop.

You can also use it with stationary bikes if you want. Just ensure you place the magnet in a place where it won’t interfere with the frame.

Based on my in-depth research and experience with bike speedometers, I highlight the following three speedometers:

• The best speedometer overall is the CatEye Padrone (also available at performancebike.com ). It’s easy to set up and use, affordable, and surprisingly capable. On the other hand, your phone can cause interference with its signal.
• The best-designed speedometer is the CatEye Quick (also available at performancebike.com ). It’s the only speedometer on this list with an out-front mount and minimalistic design. The mount is also its biggest disadvantage because it’s only compatible with rounded handlebars (and not aero ones).
• The most capable bike speedometer is the Coospo BC107 . It has ANT+ and Bluetooth connectivity, allowing you to pair it with additional sensors like power meters or HR monitors. Its disadvantage is short battery life.

Read my buyer’s guide below if you are new to bike speedometers and learn their differences from bike computers.

Speedometer vs. Bike Computer: What’s the Difference?

Basic speedometers (also called odometers) usually don’t offer as sophisticated features as bike computers .

They can measure only basic metrics like speed, average speed , ascent, descent, temperature, time, etc.

They are often incompatible with additional sensors (like power meters ), have limited connectivity, and don’t have maps for navigation purposes.

NOTE : Some speedometers have ANT+ and Bluetooth connectivity, allowing you to connect more sensors.

On the other hand, they are more affordable and have longer battery life.

Who are speedometers suitable for? Speedometers are suitable for beginners and casual riders who want a basic overview of their ride and people on a tight budget. They are unsuitable for enthusiastic riders and those who want more data from their rides.

How to Choose the Best Speedometer?

Below, I explain the most important features you should consider when buying a speedometer.

Wired or Wireless?

Speedometers have wired or wireless speed sensors.

Wired speedometers require routing a wired speed sensor. Wireless can transmit data wirelessly.

The benefits are clear – wireless speedometers are more convenient but slightly more expensive.

However, if you can, buy a wireless speedometer. They are much easier to set up and won’t add further cables to your bike.

Speedometers have monochromatic screens. They can have different colors of backlit light and sizes.

You can buy a speedometer with a larger or smaller screen size, depending on your preference.

Larger speedometers are easier to read but usually more expensive and heavier.

The following chart shows the screen sizes of the selected speedometers.

Remember, speedometers are button-based (they don’t have touchscreens).

Battery Life

The battery life of a speedometer determines how often you will need to replace (or recharge) its battery.

Thanks to their simplicity and energy-saving displays, speedometers will last months or years on one battery (unlike bike computers).

The following chart shows the claimed battery life of the best speedometers.

As you can see from the chart above, some speedometers have battery life stated in months, and some in hours only.

This is because advanced speedometers (that are almost like bike computers) have more features and connectivity, draining more battery.

Choose a simple speedometer if battery life is important to you.

Connectivity

The vast majority of speedometers are only compatible with the included speed sensors.

However, some are also compatible with cadence sensors or HR monitors, thanks to the ANT+ protocol or Bluetooth. This means they can also display your heart rate or cadence.

Unfortunately, speedometers don’t have WiFi to seamlessly upload your rides to apps like Strava.

The speedometer world is flooded with many brands. However, CatEye, Sigma, and Coospo stand out from the rest.

Remember, brands like Garmin , Wahoo , Bryton, Magene, Lezyne, etc., manufacture bike computers.

Other Features to Consider

Water resistance is significant if you live in a rainy area or are unlucky and get wet.

Most speedometers have an IPX8 water resistance rating (protection against immersion for 1 hour to a depth of 5 meters). Some have lower protection, like IPX6, IPX7, or IP67.

You don’t have to worry about using them in the rain or dropping them into a puddle.

The weight of speedometers varies from around 20 to 70g and shouldn’t be a deciding factor unless you are a weight weenie.

Bike Speedometers FAQ

Unlike bike computers, speedometers are more affordable, and their battery lasts longer thanks to power-saving monochromatic screens. Unfortunately, their features are limited and can mostly display only your basic metrics like speed, distance, ride time, etc.

Speedometers are more or less accurate but not as accurate as sophisticated bike computers. The lower accuracy results from less accurate GPS technology. Speedometers are also prone to user error, i.e., wrong set wheel circumference, etc.

The main speedometer alternative is bike computers. Bike computers are more sophisticated. They are compatible with additional sensors, have more features, and can display more metrics. On the other hand, they are more expensive and won’t last as long on one charge as basic speedometers. Read this entire article for more info.

There are multiple places to mount a speedometer. I recommend mounting it to your handlebar or stem. Some speedometers come with a dedicated mount.

The 6 Best Bike Speedometers and Computers

Unlike a car, the average bicycle doesn’t come with a speedometer that tells you how fast you’re going or an odometer that tells you the distance you’ve covered. That’s where a bike speedometer comes in; it does exactly what it says it does, and that is to measure the speed and mileage of your bike.

Beyond that, some premium bike computers can help you out with navigation and track down your performance insights. 

In this article, we’ll uncover some of the best bike speedometers you can get your hands on. Let’s get started, shall we?

Best Bike Speedometer for the Money 

Wahoo elemnt bolt gps bike computer.

In other words, you can connect it to different sensors at the same time to monitor your speed, distance, cadence, and heart rate. Plus, it features an in-built map that can take you anywhere.

Did I mention, you can also pair it with your smartphone and receive your calls, texts, and emails via the head unit? Better yet, if you’re lost on the road, the live group tracking allows your friends to find you.

Despite all its advanced features, we’re surprised it doesn’t have a colored display like its competitors. Nevertheless, that is not a deal-breaker for most people.

How about a bike speedometer that doesn’t just tell you the speed and distance but will help you to figure out your VO2 max, training load, and recovery time. Going up a hill? It will tell you the altitude acclimation and keep a record of how fast you descend a trail.

Perhaps, this is the real revolution; if you have an accident, this Garmin bike computer will automatically send your current location to saved emergency contacts. What’s more, if your bike is stolen or somebody moves it, the head unit will trigger an alarm and send a notification to your smartphone.

If you’re concerned about the battery, it can run up to 40 hours on battery saver mode; and 20 hours at optimum capacity. Of course, for a speedometer this advanced, you can download cycling apps and utilize Bluetooth, Wi-Fi, and ANT+.

Here is the kicker though; it’s damn expensive! However, if you think about what you get in return, we think it’s a bargain.

• Type: GPS enabled speedometer (Wireless)

The Lezyne Mega XL has one of the longest battery life spans for a head unit with GPS navigation.

Best Bike Speedometer – Budget Buy

Icocopro bike computer.

While most bike computers need to recharge most of the time, this unit comes with a solar panel so you can harvest power out in the sunshine. Well, you can also charge it directly and channel the extra power to its 2 batteries that can keep you going for more than 24 hours.

But that’s not all; you can ride it out in the rain due to its waterproof design, and even if it gets dark at night, the LCD backlight will make it easier to view the screen. Despite its small size, it can measure the speed, riding time, distance, cadence, burned calories, and temperature.

On the downside, don’t expect this speedometer to give you turn by turn directions. Then again, this is one of the cheapest speedometers available.

• Type: Wireless speedometer
• Screen size: 1.7 inches
• Battery life: 24+ hours
• Built with solar panel
• Auto sleep function
• Wireless and waterproof design
• LCD backlight
• Low budget speedometer
• 5 language display

It doesn’t have a navigation feature

The ICOCOPRO is a low budget bike computer that is wireless and waterproof.

CATEYE – Velo 7 Wired Bike Computer

• Displays current, max, and average speed
• total distance, trip distance,
• elapsed time,
• pace arrow, and clock.
• wired speed sensor
• battery that lasts up to three years

Here is the thing about wired bike computers; they’re very accurate and reliable. That’s because you don’t need to worry about signal inconsistency like you would on a wireless bike speedometer. Anyway, this speedometer includes a wired speed sensor in the package to make installation easier.

Once you’ve set it up, it can display the speed, distance, time, and clock. It’s waterproof too, and almost bulletproof; nothing like those fancy GPS enabled speedometers that crack a screen at the slightest impact.

If you stop briefly at a red light or coffee shop, the bike computer will automatically stop counting the stats and continue when you get back on the road. But the best part is the battery! Wait for it……. you don’t need to recharge it, and it can last up to 3 years before it’s due for a replacement.

As you probably know, a wired speedometer will make your bike look cluttered. However, that is a small price to pay if you want something accurate and consistent.

• Type: Wired 
• Screen size: N/A
• Battery life: 3 years
• Minimalism design
• Includes a wired speed sensor
• Long-lasting battery
• Easy to program
• Very accurate and reliable

The wire can clutter your bike

The Cateye Velo 7 is a wired bike computer that doesn’t need to be recharged.

DINOKA Bike Speedometer

There is nothing fancy about this wireless bike speedometer; it doesn’t have a big touchscreen or GPS navigation but it still gets the job done to measure your current speed, trip distance, and trip time. It’s also lightweight, and it doesn’t feel heavy on the handlebar when riding.

Like most high-quality speedometers on our guide, it’s waterproof enough to survive a hurricane. Also, it features a green and white-colored backlight display that makes it easier to read the screen during the day or night.

Fortunately, the package includes everything that you need to install; wireless sensors, plastic tie-wraps, stickers, 2 batteries, a mounting seat, and a manual.

However, this is not the ideal head unit if you’re looking for something compatible with your indoor training bike or electric-assist bicycle.

Setting up a Bicycle Speedometer – Explained in 7 Steps by a Pro

Charles Babbage, the father of the computer and architect of the Analytical Engine is credited with an early version of a speedometer for use on locomotives. In 1888, Josip Belusic, a Croatian, came up with the electric speedometer. Modern bike speedometers have catapulted cycling into the realm of space travel. These microcomputers help you to keep records, motivate you into knocking yourself out by goading you to ‘go where no man has gone before’. They are extremely simple devices that give a lot of information back, so there is no call to get intimidated by complex-sounding installations or functions. Here we take a look at how to hook them up, so let’s dive into bike computer installation.

What Is a Speedometer?

As related to bicycles, it’s called a cyclo-computer. Earlier on, this would have been a misnomer; there are no chips, ICs or whathaveyou. It was electro-magnetic in essence. A speedometer is fundamentally a device mounted on a bike that calculates and furnishes trip information. A speedometer gives you an instantaneous reading of your current speed. It is usually augmented by an odometer which is a display of distance covered. The basic working principle of an analog speedometer on a bike is shown below.

Modern versions incorporate an electronic bike computer sensor that utilizes the time taken per revolution as the basis for all other computations.

How to Bicycle Speedometer Setup

Bicycle speedometers are small computers that are attached and start with the measuring of your wheel revolutions. Sensors are located on your bike wheels and wheel size being known, computes your speed. The tricky bit here is calibration. If that is not accurate, the exercise becomes meaningless.

Essential Tools

• Soldering Iron
• Wire cutters
• A stripper or knife
• Bicycle tools

The computer sensor goes on to the fork opposite the brakes on the front mount. The sensor can be affixed at any point on the fork, just make sure you can access it easily. If no specific attachments were advised, secure the sensor with cable ties.

The sensor wire should be run up the back and outer part of the shock absorber. It is highly desirable that the wire is protected from the undergrowth that you encounter in your rides as also keeping the wire away from the wheel in motion. A tip here is to encase the wire in plastic tubing of small diameter and affix it using cable ties.

Attach the computer display mount on the handlebar where it is easy to see. Every mount differs slightly. So yours should be secured according to your computers’design.

Mate the sensor wire and the computer mount, secure with cable ties, give everything a once over, attach additional cable ties if required. Bear in mind to leave sufficient slack so that the handlebars and front wheel are free to turn unhindered.

Clip the sensor to the spokes carefully choosing the location. The magnet should pass close to the sensor at every turn of the wheel. It should be no further than ¼ inch away when it passes the sensor.

Enter the diameter of your bicycle tire into the computer. This will be the basis of all calculations so there is little scope of error here. The measurement is readily available from the marking on the tire itself or the manual will tell you.

Turn the wheel a couple of times. A non-zero reading on the display tells you that it is working. To check the accuracy you can cycle between two consecutive mile markers and check the reading.

Tips for Setting up a Speedometer

• Mount the magnet as close to the hub as possible so that it passes the sensor slowly giving an accurate reading.
• After installing the magnet, position the sensor suitably on the fork. Test the computer, make adjustments, then secure.
• Cable ties are unsightly. You can use transparent plastic tape that comes in 2” rolls. Clean the surface properly though before putting the tape on.
• The wire should lead up the back of the fork. This is both aesthetic and aerodynamic.
• If you are fitting a cyclometer on a bike with cantilever brakes , install sensor and magnet on the left if possible.

As you saw, a bicycle speedometer setup is a walk in the park. To make it as easy as stealing candy from a baby, there are wireless computers now available and no, they are not expensive. No messy wires and whathaveyou. So make the best of what you have gleaned from this guide and set up your speedometer if you don’t have one already. Some speedometers give a lot more information including your heart rate. The choice is vast.

As a kid I inherited the love for mountain bikes from my father who used to ride for weeks through the Colorado trail in the city of Denver. He had his gang, and I followed pretty much the same track.

Later on, my interest in biking grew more after joining the Enduro race back in 2013. My buddies and I also participated in the Downhill racing for the third consecutive year, and it’s been an amazing experience.

What is an eBike Speed Sensor? (Defining, Function and Troubleshooting)

The fun of riding an electric bike is seeing the road roll by without breaking a sweat. The battery pack and motor do most of the work, but some other components help control that power.

Glancing down at your display and seeing the speedometer showing speeds that might be faster than you could pedal on your own.  But how does it work?

An eBike Speed Sensor is a proximity switch that counts a bike wheel rotation.  The sensor sends a signal to the display which calculates the bike speed using the wheel diameter. Additionally, speed sensors indicates movement of the bike allowing power to be applied during pedal assist mode. On most mid-drive conversion kits, the speed sensor is located on the bike chainstay with a magnet on the bike spokes.

Did you Know You Can Convert a Regular MTB to Electric?

Bafang a leader in DIY electric bike conversions has a mid-drive kit that will fit on most regular bikes. I’d recommend the BBSHD kit, it’s a complete setup with a huge capacity battery and a 1000 watt motor. Why this setup?

• Heavy duty 1000 watt motor (built for cargo bikes)
• +50 volt 17.5 Ah battery for speed and distance
• Easy installation with provided tools.

If you’re considering a conversion, do what I’m doing get the BANFANG BBSHD 1000w eBike Conversion with Battery

How Does an Electric Bike Speed Sensor Work?

The digital signal sent to the electric bike display has two primary functions. 

1. A simple speed calculation is made using the wheel diameter times that weird pi (3.1416) number, which provides the wheel circumference. Example: a 26 in tire X 3.1416 = 81.86 inches traveled in one rotation.  Then using the time interval between signals, a rotation per time is calculated.  For example, it takes 776 rotations per hour to go 1 MPH.  A great illustration would be to visualize the bike wheel turning at nearly 20,000 rotations per hour or 323 RPM (rotations per minute) would equal 25 mph

2. The Speed Sensor also detects movement, think of this function as an “OKAY” signal.  When the display senses wheel movement from the speed sensor it ALLOWs power to go to the motor.  Mostly used during PAS (Pedal Assist System) the movement signal turns on the power while pedaling because the sensor detects movement.

To a lesser degree, the speed sensor helps in calculating the distance remaining in the battery capacity. 

RIDE e MTB Pro Tip: With eBikes growing in popularity learning all the terms and definitions can be a bit overwhelming. Let me help with this comprehensive glossary. 👉 eBike Glossary

Why is a Speed Sensor Needed?

As a rider, we need to understand how fast the bike is going to keep up with traffic.   Also, no one wants an electric bike to take off when the bike is stationary.  The speed sensor is needed to control these electric bike functions.

Differences Between Speed Sensors and Cadence Sensors on Electric Bikes

On a hub motor eBike the cadence sensor gets a signal from the bike crank.  Which feeds the signal into the display when using the pedal assist system.  Hub motors have speed sensors, they are located internal to the hub motor housing.

RIDE e MTB Tip: Are you thinking about building an eBike? It isn’t very hard – Heck I’ve got step by step instructions with videos along with all the tools. Check it out 👉 How to Build a Mid-Drive Electric Bike

Common Speed Sensor Problems

The most common problem with speed sensors is the gap between the magnet and sensor being too wide.  The recommended gap should be 4 to 6 mm.  (less than ¼ inch) Test the spacing by moving the magnet (on the wheel spoke) past the speed sensor and check for an indicator light.

Another common problem is the wire connections are loose or broken. The connection joints are designed to be water resistant so in turn, they are tight.  Broken wires can happen pretty easily since the wires are close to the tires and spokes.  It’s easy for a branch to get caught in the tire/spokes and get swiped by the wires damaging them

Sometimes when installing and connecting the wires the tiny pongs in the connector can get bent or damaged.

Speed Sensor Error Codes on Banfang Systems

Many Banfang displays will show an error.  My display calls out the speed sensor. 

The common error codes are:

Test a Speed Sensor

After setting the wheel size within the display.  The best test is to use the bike and check for error codes.  If you want to check how accurate the speed is, use a GPS app like Google Maps on your phone.

Another test is to spin the rear wheel and watch for the indicator light on the pick up unit located on the chainstay .

How to Attach a Phone to an Ebike?

I love biking, and I also like playing music while riding.  A couple of years ago I found a biking phone mount and I’ve been recommending it for a while.  It’s called Quad-Lock.  The system has two parts, the first is a sturdy handlebar mount and a low-profile phone cover.

The system securely “Locks” your phone on.  I’ve crashed mountain biking – YES over the handlebars and my phone has remained securely connected.

Check out the mounting system at Amazon with this shortcut link 👉 Quad-Lock Phone Mount

Can You Bypass the Speed Sensor to Go Faster?

Yes, there are a couple of ways to trick the speed sensor system into thinking the bike is going slower, so more power can be applied to go faster.

1. If you mount the magnet to a slower rotating item.  For example, the pedal crank rotates at a fraction of the speed of the wheel.  If you glue the magnet to the inside of the crank and mount the sensor opposite on the frame, you’ll “trick” the sensor.

2. If your electric bike display has a setting for the wheel size you can adjust the size smaller.  For example on a 26-inch wheel bike setting the display at 20 in.

Neither of these options is a good idea though.  If you desire to make your bike, go faster the best way is to better understand the gearing, motor, and battery options and jump into a custom high-power e-bike build.

Frequently Asked Question

Why is my ebike going slow.

I would recommend three things; 1. Is the battery fully charged? 2. Check tire pressure, low air pressure in tires will add considerable rolling resistance. (wide fat tires can be slower as well) 3. Less obvious can be the environment, a slight increase in the grade (hill) and wind resistance will dramatically affect electric bike speed.

More Than Leg Power

A speed sensor provide an essential component in an eBike system.  An accurate link from the tire motion to the display and application of power is critical.

This little e-bike hack can make electric bikes 50% faster instantly

Electric bicycles are subject to various speed limits around the world, but the 25 km/h (15.5 mph) speed limit in places like the EU and Australia is particularly frustrating to riders who are in search of just a bit more “oomph” in their bikes. But a new device is making it easy to increase the top speed of electric bicycles without making any major modifications to the electric bike’s drive system.

Many electric bicycles use a magnetic speed sensor on the rear wheel to measure the traveling speed of the electric bike.

When the e-bike reaches a pre-programmed top speed – as low as 25 km/h or 15.5 mph in many countries – the motor power cuts out and riders can only reach higher speeds under their own leg power or with the help of gravity.

The Speedi device tricks the speed sensor on the rear wheel into spinning more slowly, effectively raising the e-bike’s electronic speed limit by around 50%. It uses a small gear with a 1:1.5 ratio to slow down the speed sensor. That would effectively turn a 15.5 mph e-bike into a more thrilling 23 mph ride.

I’ll let the Speedi folks describe the use case in their own words:

Sick of hitting your e-bikes speed limit when you’re  friken given ‘er the beans?!   Want to smoke ya mates? Designed, tested and manufactured in New Zealand, our Speedi uses a mechanical planetary gear system to increase your standard e-bike speed by 1.5.

A nice feature with this method of “hacking” the bike’s top speed is that it doesn’t interfere with other measurements being registered by the drive system, such as torque, power, temperature, etc.

It also doesn’t require the user to open or modify the motor or drive system.

Manufacturers will probably frown at the device’s use, or could even consider it a warranty-voiding action. So users should probably check with their manufacturer first if they want to play it safe.

And of course you’ll want to check with your local regulations to determine if the device is considered illegal on public roads. If so, off-road e-biking may be your only chance to employ a device like this.

The Speedi team at NLS Components has already developed units that are compatible with bikes from Trek, Specialized, Giant, and Santa Cruz. They also offer custom units that can potentially be made compatible with other brands, as required.

The devices are priced at NZD $160, or around US $114.

Traveling at 50% higher speeds though – that’s priceless.

Electrek ‘s take

I know this is going to be a bit controversial, but I certainly understand the desire to ride faster than the EU speed limit. Hitting the 15.5 mph wall is frustrating, especially when non-electric bikes can easily be pedaled faster.

The thing I worry more about is if someone is able to put this on a Class 3 e-bike or a speed pedelec in the EU, effectively turning a 28 mph or 45 km/h e-bike into a lightweight motorcycle. I’m not sure if many such e-bikes actually have the power to add 50% more speed on top of the 28 mph limit, but the 15.5 mph versions certainly have room to run up to 23 mph.

The extra wear and tear on the drivetrain and components is likely reason enough for a manufacturer to claim the warranty is voided, which sounds fair to me. They factor in all their warranty planning based on their e-bikes being used as designed. So if you’re going to modify your e-bike to go faster, I think that should be on you.

Hi Everyone, I am looking to buy my first e-bike and have narrowed it down to NCM Moscow and Ride1up 500 Series. Both looks good so looking some help to decide which one to go for if I am planning to buy a new e-bike. I am also wondering if it's worth it to even think about building my own by buying a brand like Trek Dual Sport 3/4 and then installing the front/rear ebikeling kit. Thanks in advance for your help!

If you're building a kit, start with one motor, unless you're skilled electrically, but the NCM seems like a nice bike, and you won't be able to match the buy vs build cost, unless you go for a sketchy battery. Unless he has fixed the oversight/flaw/blunder, the ebikeling geared motor LCD kits use a controller that doesn't have a speed sensor, so odometer/speedometer don't work when motor is coasting. I asked a recent ebikeling user this year about that, and it's still a bug. If you're buying the 1000+W direct drive motor. this is not an issue, but it's a different kind of ride. I started with an ebikeling 500W geared motor six years ago, That motor still runs great. I also built a dual drive using his geared 500W motor on the front of my fat tire bike, and have a third ebike that I gave away using the geared 500W rear motor.  

From Ebikeling I am looking at https://www.amazon.com/gp/product/B07MG76XWC/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1
