Riding an e-bike is one of the most exciting and practical ways to get around. Electric bikes make hills easier and long distances less tiring. But after some time, many riders want to know: How can I make my e-bike go faster? Whether you want more speed for commuting, fun, or just to keep up with traffic, there are safe and smart ways to unlock more power from your e-bike.
This article will guide you step by step through proven methods to make an e-bike faster. You’ll learn about software settings, hardware upgrades, legal limits, and what really works for real riders. If you’re new to e-bike tuning, don’t worry—we’ll explain everything in clear, simple language.
By the end, you’ll know how to get the most speed from your e-bike without risking safety or breaking the law.
Understanding What Limits E-bike Speed
Before changing anything, it’s important to understand what controls your e-bike’s speed. There are three main factors:
- Motor power – The strength of the electric motor, usually measured in watts.
- Controller settings – The electronic brain that decides how much power the motor gets.
- Legal speed limits – Laws that limit e-bike speed in different countries or states.
Other factors like battery voltage, weight, and tire type also play a part, but the motor and controller are the core. Most e-bikes have a factory speed limit to follow local laws. In many places, this is 25 or 28 km/h (15 or 17 mph). Some e-bikes slow down automatically when you reach this limit.
If you want to go faster, you must work with these limits. But remember, changing your e-bike may affect its warranty and legality. Always check your local laws before making changes.
Tuning The Controller For More Speed
The controller is like the brain of your e-bike. It manages how much power goes to the motor. Most e-bikes have a speed limiter set in the controller’s software.
Removing Or Raising The Speed Limiter
Some e-bikes let you change the speed limit through the display or by using a special sequence of buttons. For example:
- Hold the up and down arrows together for a few seconds.
- Go into the settings menu.
- Find the speed limit option and increase it.
Not all e-bikes allow this. Many brands lock the settings to avoid illegal riding. For these, you need a tuning kit or special device. These kits “trick” the controller into letting the motor run faster. Popular brands like Bosch, Shimano, or Yamaha have tuning kits available.
Example: Bosch Motor Tuning
For a Bosch mid-drive motor, you can use a tuning device that plugs into the motor’s sensor cable. Once installed, the display may show half your real speed, but the motor will not cut off at the standard limit. Riders have reported reaching speeds up to 45 km/h (28 mph) on flat roads.
Important: Using a tuning kit may void your warranty and could be illegal on public roads. Use it responsibly.

Upgrading The Battery For More Power
The battery voltage has a big effect on how fast your e-bike can go. Most e-bikes use 36V or 48V batteries, but some high-performance models use 52V or even 72V.
How Battery Voltage Affects Speed
Higher voltage means more power for the motor. If your controller and motor can handle more voltage, upgrading the battery will give you:
- Faster acceleration
- Higher top speed
- More consistent power on hills
However, you can’t simply swap a 36V battery for a 52V one without checking compatibility. The controller and motor must be rated for the higher voltage. Using the wrong battery can damage your e-bike or cause safety problems.
Example: 36v Vs. 48v Battery
Here’s a simple comparison:
| Battery Voltage | Typical Top Speed | Acceleration |
|---|---|---|
| 36V | 25-28 km/h (15-17 mph) | Standard |
| 48V | 32-38 km/h (20-24 mph) | Faster |
| 52V | Up to 45 km/h (28 mph) | Much faster |
If you’re not sure about voltage upgrades, talk to a qualified e-bike technician.
Switching To A More Powerful Motor
The motor is the heart of your e-bike. Most city e-bikes use a 250W or 350W motor. If you want much higher speed, you’ll need a more powerful motor, such as 500W, 750W, or even 1000W.
Motor Power And Speed
Here’s how motor size affects speed:
| Motor Power | Possible Top Speed | Best Use |
|---|---|---|
| 250W | 25-28 km/h (15-17 mph) | Urban commuting |
| 500W | 32-38 km/h (20-24 mph) | Hills, cargo |
| 750W | Up to 45 km/h (28 mph) | Off-road, speed |
| 1000W+ | 50+ km/h (31+ mph) | Extreme, private roads |
Upgrading the motor is a big job. You may need a new controller, bigger battery, and stronger frame. This can be expensive and complex, but for some riders, it’s the only way to get true high speed.
Reducing Bike Weight For More Speed
A lighter e-bike is a faster e-bike. While the motor helps, less weight means less work for the motor and better acceleration.
How To Reduce Weight
- Remove unnecessary accessories – Take off baskets, racks, or heavy locks if you don’t need them.
- Use lighter tires – Swap heavy, thick tires for lighter, smoother road tires.
- Choose a lighter battery – Some batteries are smaller and lighter but have less range.
- Replace parts with lighter versions – For example, aluminum or carbon fiber handlebars and seat posts.
Even small changes in weight can make a difference, especially for climbing hills.
Upgrading Tires For Less Rolling Resistance
Tires have a big effect on speed. Wide, knobby tires are slow. Narrow, smooth tires roll faster.
Choosing The Right Tires
Look for slick or semi-slick tires made for road use. These have less rolling resistance and let you go faster with the same power. Inflate your tires to the recommended pressure; under-inflated tires slow you down.
Example: Tire Width And Speed
A 2. 0-inch wide tire is much slower than a 1. 5-inch tire on pavement. Many riders report gaining 2-3 km/h just by switching to road tires.
Improving Aerodynamics
Wind resistance increases a lot as you go faster. At high speeds, most of the motor’s energy fights the wind.
How To Be More Aerodynamic
- Lower your riding position – Bend your elbows and lean forward.
- Remove baskets and racks – These catch the wind.
- Wear tighter clothing – Loose jackets or bags slow you down.
Aerodynamic changes can add 2-5 km/h to your top speed, especially above 25 km/h.
Keeping The Bike Well-maintained
A well-maintained e-bike runs faster. Dirt, rust, and worn parts create resistance.
Maintenance Tips
- Clean and lubricate the chain – A dirty chain wastes energy.
- True the wheels – Wobbly wheels slow you down.
- Check brakes – Brakes that rub the wheel create drag.
- Keep tires pumped – Low pressure increases rolling resistance.
Regular maintenance is one of the simplest ways to keep your e-bike at its best speed.

Using Pedal Power Together With The Motor
Many e-bikes have pedal assist modes. Using your legs at the same time as the motor can push your speed higher, especially above the motor’s cut-off speed.
How Pedal Assist Helps
If the motor stops helping at 28 km/h, you can keep pedaling to go faster. Shifting to a higher gear and pedaling hard can add several km/h. Some riders reach 35 km/h or more this way, though it takes effort.
Upgrading The Controller
The controller decides how much power goes from the battery to the motor. Upgrading to a better controller can sometimes unlock more speed.
What To Check Before Upgrading
- Compatibility with your motor and battery
- Maximum current and voltage rating
- Features like adjustable speed limits or custom modes
A high-quality controller can make the motor feel stronger and smoother. But, as with other upgrades, it’s important to match all parts.
Installing A Throttle (if Not Already Present)
Some e-bikes only have pedal assist. Adding a throttle lets you control speed without pedaling, which can be useful for short bursts of speed.
Throttle Types
- Twist throttle – Like a motorcycle
- Thumb throttle – Press with your thumb
Adding a throttle requires wiring it to your controller. Check local laws, as some regions do not allow throttles on e-bikes.
Managing Rider And Cargo Weight
The total weight the motor must move affects speed. If you often carry heavy bags or ride with a passenger, your e-bike will be slower.
Tips For Managing Weight
- Travel light whenever possible.
- Distribute weight evenly for better balance.
- Remove cargo racks or child seats when not needed.
Even losing a few kilograms can give noticeable speed improvement.
Legal And Safety Concerns
Making your e-bike faster is exciting, but always consider the law and safety. In many places, e-bikes are limited to 25 or 28 km/h on public roads. Faster bikes may be considered mopeds or motorcycles, requiring a license, insurance, and helmet.
Real Risks
- Higher speed means less reaction time
- Brakes and tires must be strong enough
- Insurance may not cover accidents with modified e-bikes
Ride responsibly and be aware of your local rules.
Common Mistakes To Avoid
- Ignoring compatibility – Mixing the wrong battery, motor, or controller can break your e-bike.
- Overheating the motor – Too much power can cause damage.
- Forgetting about brakes – Faster speed requires better stopping power.
- Neglecting local laws – Riding a modified e-bike illegally can result in fines or confiscation.

Real-world Example: How Upgrades Can Add Speed
Let’s look at a typical case. A rider with a 250W, 36V e-bike wants more speed. They:
- Upgrade to a 48V battery (after confirming compatibility).
- Install a tuning kit to remove the speed limiter.
- Replace the tires with narrow, smooth road tires.
- Lower their riding position for better aerodynamics.
Result: The rider reports a top speed increase from 25 km/h to 38 km/h on flat roads, with better acceleration and range. This shows that combining several small upgrades can have a big effect.
How To Decide Which Upgrades To Try
Not all changes are equal. Here’s how the most common upgrades compare for speed and difficulty:
| Upgrade | Speed Gain | Cost | Difficulty |
|---|---|---|---|
| Tuning kit | High | Medium | Medium |
| Battery upgrade | Medium | High | High |
| Motor upgrade | Very High | Very High | Very High |
| Lighter tires | Low | Low | Low |
| Better aerodynamics | Low | None | Low |
If you’re new to e-bike upgrades, start with tires, weight reduction, and aerodynamics before trying complex electrical upgrades.
