Riding an e-bike brings both fun and practicality to daily life. For many, it’s a fast way to commute, exercise, or explore the outdoors. But after using an e-bike for a while, you might start to wonder how to make your e-bike go faster.
Maybe you want to reach your destination quicker or just enjoy a stronger breeze as you ride. The good news is, there are safe and effective ways to boost your e-bike’s speed. This guide will show you how, with clear explanations and real-world tips.
Understanding What Limits E-bike Speed
Before making changes, it’s important to know what controls the speed of your e-bike. Most e-bikes have a speed limiter set by the manufacturer. In many countries, the legal speed limit for e-bikes is 25 km/h (15.5 mph) or 32 km/h (20 mph) in the US. The motor power, battery voltage, controller settings, and tire size all play a role. If you want to go faster, you’ll need to understand and sometimes adjust these parts.
Legal And Safety Considerations
Increasing your e-bike’s speed may mean you’re no longer following local laws. In some places, making your e-bike go faster could mean it is no longer considered a bicycle, but a moped or motorcycle. This can affect where you can ride, insurance requirements, and even your safety.
Always check your local regulations before making any modifications.
Safety is also critical. More speed means more risk, especially if your brakes or tires are not designed for higher speeds. Upgrading these parts along with your speed can keep you and others safe.

Ways To Make Your E-bike Go Faster
Let’s explore the most effective ways to increase your e-bike’s speed. Each method comes with benefits, challenges, and things to consider.
1. Remove Or Adjust The Speed Limiter
Many e-bikes have a speed limiter that restricts how fast you can go. Sometimes, you can adjust or remove this limiter by following the instructions in your bike’s manual. For some e-bikes, there are buttons or codes you can use to unlock a higher top speed. In other cases, you may need to buy a speed tuning kit or special device that tricks the bike’s computer.
Be aware: Removing the limiter can void your warranty and may not be legal everywhere.
2. Upgrade The Battery
A higher voltage battery can make the motor spin faster. For example, switching from a 36V battery to a 48V battery can give a clear speed boost. But not all motors and controllers can handle more voltage. Check your e-bike’s specifications before upgrading.
Here’s a simple comparison of how battery voltage affects speed:
| Battery Voltage | Estimated Top Speed |
|---|---|
| 36V | 25-28 km/h (15-17 mph) |
| 48V | 32-40 km/h (20-25 mph) |
| 52V | Up to 45 km/h (28 mph) |
A higher voltage battery also improves acceleration and power, but may shorten the life of your motor if not compatible.
3. Change The Controller
The controller acts as the brain of your e-bike, managing the flow of power from the battery to the motor. Upgrading the controller can allow more current to reach the motor, increasing speed and torque. Some aftermarket controllers also let you adjust speed settings through an app or display.
However, a powerful controller requires a battery and motor that can handle higher current. Always match the controller’s specs with your other e-bike components.
4. Upgrade The Motor
If your motor is weak or designed for low-speed use, you may hit a speed wall. Upgrading to a more powerful motor—such as moving from 250W to 500W or 750W—can push your e-bike to higher speeds. Hub motors and mid-drive motors both have upgrade options.
But keep in mind, a stronger motor usually means more battery usage. Here’s a quick look at how motor power affects performance:
| Motor Power | Top Speed | Climbing Power |
|---|---|---|
| 250W | 25 km/h (15.5 mph) | Low |
| 500W | 32 km/h (20 mph) | Medium |
| 750W | 40+ km/h (25+ mph) | High |
5. Use Thinner Or High-pressure Tires
Wide, knobby tires are great for off-road use but create more rolling resistance. Switching to narrow, smooth tires and inflating them to a higher pressure reduces friction, letting you go faster with the same effort.
Check the recommended pressure on your tire’s sidewall. Over-inflating can cause a rough ride or even a blowout, so stay within safe limits.
6. Reduce The Weight
Every extra kilogram makes your e-bike work harder. Remove baskets, racks, or other heavy accessories you don’t need. If you carry a backpack, pack light. Even changing to lighter wheels or a lightweight seat can help.
While this won’t add 10 km/h to your speed, it makes acceleration easier and improves efficiency, especially on hills.
7. Keep The Chain And Drivetrain Clean
A dirty chain or gears can steal power from your ride. Clean and lubricate your chain every few weeks, especially after riding in rain or mud. Also, check the gear alignment and make sure your derailleur is working smoothly.
A well-maintained drivetrain can make a noticeable difference in speed and feel.
8. Adjust Pedal Assist Settings
Most e-bikes have different pedal assist levels. Setting your bike to a higher level (like 4 or 5 on a 5-level system) gives you more power from the motor. Some advanced e-bikes let you customize these levels using the display or a smartphone app.
If you find yourself running out of power quickly, use higher assist only when you need it most, such as on hills or when accelerating.
9. Change The Gear Ratio
E-bikes with gears allow you to change the gear ratio between your pedals and the wheels. Using a larger front chainring or a smaller rear cog gives more speed per pedal stroke. However, this makes it harder to start from a stop or climb hills.
Here’s an example:
- Standard gear: 44T chainring, 16T cog (easier to pedal, less speed)
- Upgraded gear: 52T chainring, 14T cog (harder to pedal, more speed)
Changing gears is a low-cost way to get a little more speed, especially for those who like to pedal hard.
10. Tuck In While Riding
Your riding position affects aerodynamics. Sitting upright catches more wind, slowing you down. Tucking your elbows and lowering your upper body lets you cut through the air better, just like a racing cyclist.
Small changes in position can add 2–3 km/h (1–2 mph) without any mechanical upgrades.
11. Upgrade The Firmware
Some e-bikes have software that controls speed and power. Manufacturers sometimes release firmware updates that improve performance. Advanced users can also install custom firmware to unlock higher speeds or more pedal assist levels.
Be careful: Custom firmware can void your warranty and may make your bike illegal for road use.
12. Use A Better Charger
Fast chargers can charge your battery more quickly, but they don’t directly make your bike faster. However, keeping your battery topped up and in good condition means you’re always getting the best possible performance.
A weak or old charger can leave your battery undercharged, which reduces speed and range.
13. Ride On Smooth, Hard Surfaces
The type of road or path you ride on matters. Smooth asphalt or concrete allows for higher speeds than gravel or grass. Plan your routes to use the best surfaces available.
Wet or dirty roads can also slow you down, so adjust your expectations in bad weather.
14. Use A Windshield Or Fairing
This is a trick from motorcycles and racing bikes. Adding a small windshield or fairing can help you cut through the wind, especially at speeds above 30 km/h (18 mph). They are not common on regular e-bikes, but some long-distance riders use them.
This upgrade is for advanced users and those who want every possible edge.
15. Maintain Tire Condition
Worn or under-inflated tires increase rolling resistance and reduce speed. Check your tires for cuts, embedded glass, or low tread. Replace them if they’re worn out.
Use tires designed for e-bike speeds, as they’re built to handle extra weight and power.
16. Upgrade To Ceramic Bearings
Most e-bikes use steel bearings in the wheels and pedals. Ceramic bearings are smoother and have less friction, which can translate to a bit more speed. This is a small gain, but racers and enthusiasts sometimes use them.
The cost can be high compared to the benefit, so only consider this if you want the best possible setup.
17. Use Lighter Wheels
Heavy wheels take more energy to spin up to speed. Switching to lighter aluminum or carbon wheels reduces the weight you must move every time you pedal. This upgrade helps most when accelerating, but can also add a small top speed increase.
Make sure any new wheels are compatible with your e-bike’s brakes and motor system.
18. Keep The Battery Cool
Batteries lose power when they get too hot. On hot days, park your e-bike in the shade and avoid riding in the hottest part of the day. A cool battery delivers more consistent power and can help maintain higher speeds.
Some riders even use battery covers or bags with reflective material to keep things cooler.
19. Use Higher Quality Electrical Cables
Cheap or old cables can limit the flow of electricity from your battery to the motor. Upgrading to thicker, high-quality cables ensures you’re getting the most out of your electrical system.
This is an advanced modification, but for some DIY e-bike builders, it’s an easy way to remove bottlenecks.
20. Regular Maintenance Checks
Fast e-bikes need more attention. Tighten all bolts, check the brakes, adjust the gears, and make sure the electrical connectors are clean and tight. A small problem, like a loose connector or worn brake pad, can rob you of speed and even cause accidents.
Set a reminder to check your e-bike every month, especially if you ride fast or far.
Key Mistakes To Avoid
Some new e-bike owners make common mistakes when trying to go faster:
- Ignoring local laws and getting fined or having their bike confiscated
- Using parts that are not compatible, causing electrical failures
- Neglecting brakes and tires, leading to dangerous situations
- Forgetting that higher speed means less range—batteries drain faster at top speed
When in doubt, talk to a local e-bike mechanic or join online e-bike forums for advice.
