The Short Answer is:
To make an e-bike faster, one can adjust the battery or controller to eliminate the manufacturer's speed restrictions (derestrict), adjust the pedal assist, fully charge the battery, and adjust the max speed in advanced settings. Additionally, adding more air to the tires and removing any speed limiters can help increase speed.
E-bikes are bicycles that use rechargeable batteries and have a motor that can assist the rider up to a certain speed. The maximum speed of an e-bike depends on its class, with Class 1 and 2 e-bikes typically limited to 20 mph (32 km/h) and Class 3 e-bikes limited to 28 mph (45 km/h).

How To Make E-Bikes Faster?
There are several ways to make e-bikes faster. One way is to adjust the battery or controller to eliminate the manufacturer’s speed restrictions (derestrict). This can be done by changing the wheel size in the bike’s settings or downloading an app like the EBT E-Bike Tuning App.
Another way is to adjust the level of pedal assist on the bike’s LCD display. Additionally, fully charging the battery before riding can increase speed.
Changing parts and doing maintenance can also help increase an e-bike’s speed. For example, switching to wind-resistant tires, adding more air to tires, and reducing weight through minimal accessories can all help increase speed.
Removing any speed limiters programmed into some e-bikes can also help increase speed.
There are also devices available that can make e-bikes faster. The Speedi device, for example, tricks the speed sensor on the rear wheel into spinning more slowly, effectively raising the e-bike’s electronic speed limit by around 50%.
However, it is important to note that modifying an e-bike may void its warranty and could potentially be illegal depending on local laws and regulations.
Understanding the legal limitations of e-bike speed
The legal limitations of e-bike speed vary depending on the classification of the bike and state regulations. In general, the federal speed limit for e-bikes is 20 miles per hour or less under motor power alone.
Class 1 and 2 bikes are also limited to this speed limit. However, class 3 e-bikes are allowed to travel at speeds up to 28 mph in some states.
The electric motor capacity is also limited to 250 watts in some places. It’s important to check your state’s specific regulations regarding e-bike speed limits.
The factors that affect e-bike speed
Several factors can affect the speed of an e-bike, including the power of the motor, battery capacity, and bike design. Other factors that can impact e-bike speed include riding speed, assist level, gear selection, tire pressure, and terrain.
Choosing the right e-bike for maximum speed
Class 1 e-bikes are the best choice for maximum speed, as they have a top speed of 20 mph and power is only delivered via pedal assist.
Class 2 e-bikes also have a top speed of 20 mph, but they may go faster if you pedal hard or go downhill.
Class 3 e-bikes have a top speed of 28 mph, but this is not the fastest option available.
When choosing an e-bike, other features to consider include motor type, battery capacity, and frame material.
Upgrading your e-bike components for improved speed
There are several ways to upgrade your e-bike components for improved speed. You can consider swapping out the motor for one with a higher RPM rating.
Upgrading the cranks or switching out the tires can also make a difference. Additionally, adding a second battery or GPS tracking can be helpful.
If you have a standard bike, you can get an e-bike conversion kit. However, it’s important to note that some upgrades may affect the legal classification of your e-bike and could require additional registration or licensing.
Optimizing your e-bike battery for increased speed
Optimizing your e-bike battery for increased speed can be achieved by switching to a higher voltage system, hitting corners at speed and on the right line to save energy, pedaling when starting out from a stop, and using a higher voltage battery.
Additionally, reducing speed can help conserve power and increase range.
Fine-tuning your e-bike motor settings for better speed
To fine-tune your e-bike motor settings for better speed, you can consider tuning your electric bike by removing the pedal assistance limit, unlocking the speed limit and derestricting your e-bike, or installing a special chip into the control unit to ensure acceleration up to 50 km/h without damaging the engine or e-bike.
You can also swap your motor with a higher RPM rating for your specific voltage to increase speed. However, it is important to note that modifying your e-bike may not be legal in some areas and could void your warranty.
Improving your e-bike aerodynamics for greater speed
Improving the aerodynamics of your e-bike can help increase its speed. Reducing air resistance and drag can be achieved by using a more aerodynamic riding position, wearing tight-fitting clothing, and adding aerodynamic accessories such as fairings or wheel covers.
Additionally, increasing the voltage of your battery can also improve motor speed and increase the bike’s top speed. Proper tire pressure is also important for improving efficiency and range.
The risks and consequences of illegally modifying e-bike speed
Illegally modifying the speed of an e-bike can be dangerous and risky. It may also void the warranty and result in financial or legal trouble.
Additionally, it is illegal and carries fines. Modifying the battery or motor can also be dangerous and void the warranty.
There is a risk of accidents that could seriously injure yourself or others if you modify your e-bike. Riding manipulated e-bikes on public roads may lead to technical problems and serious legal consequences.
To avoid these risks, only use approved parts and repair centers to work on your e-bike, and avoid illegal tuning.
Frequently Asked Questions related to maximizing e-bike speed:
How fast can an e-bike go?
Electric bikes can reach speeds of up to 28 mph (45 km/h) depending on their classification.
Class 1 and 2 ebikes can reach speeds of 20 mph (32 km/h), while Class 3 ebikes can reach 28 mph (45 km/h).
Some electric bikes have higher top speeds, but they do not fit into the current classification system. In Race Track mode, the maximum speed may be faster than 28 mph depending on many factors such as rider strength, tire pressure, wind, and ambient temperature.
A 2000W electric bike can easily reach speeds of 38 mph (60 km/h), some of which can even exceed 43 mph (70 km/h).
What battery upgrades can I make to increase my e-bike speed?
To increase the speed of an e-bike, one can upgrade the battery by choosing a higher-voltage battery. A higher voltage battery will provide more power to the motor and thus increase the speed.
However, it is important to note that upgrading the battery may not always be a DIY-friendly project. Other methods to increase e-bike power include adjusting the pot screw or disconnecting the power smoother plug, but these methods may not necessarily increase speed.
How can I adjust my e-bike motor settings for better speed?
There are several ways to adjust e-bike motor settings for better speed. One way is to swap out the battery for a higher voltage battery.
Another method is to adjust the speed limiter settings on the onboard computer. There are also devices like Speedi that can trick the speed sensor into spinning more slowly, effectively raising the e-bike’s electronic speed limit.
It’s important to note that there are some basic physics at work with the motor that governs how fast an e-bike can go, so there may be limits to how much you can increase its speed.
What are the risks of illegally modifying e-bike speed?
Illegally modifying the speed of an e-bike can be dangerous and risky. It is also illegal and can result in fines or legal trouble. Modifying the bike’s battery or motor may void the warranty. Additionally, there is a risk of accidents that could cause serious injury to yourself or others.
How can I safely and legally maximize the speed of my e-bike?
It is important to note that the speed of an e-bike is often limited by law, and exceeding the legal limit can result in fines or other penalties.
However, there are some ways to safely and legally increase the speed of your e-bike. Some tips include riding with a fully charged battery, using smoother tires and pumping them up, swapping your motor for one with a higher RPM rating, and tuning your brakes.
It is also possible to delimit an e-bike, which involves removing the pedal assistance limit, but this should only be done if it is legal in your area.
Conclusion and recommendations for safely maximizing e-bike speed
To safely maximize e-bike speed, here are some recommendations:
- Swap to a higher voltage battery
