Maximum Speed Limit for Electric Bikes in the UK

The maximum speed limit for electric bikes (EAPCs - Electrically Assisted Pedal Cycles) in the UK is 15.5 mph (25 km/h). This means that the electric assistance on the bike must cease when it reaches this speed. E-bikes that meet the EAPC requirements are considered regular bicycles, and riders do not need a license to operate them. As long as you are over 14 years old and your e-bike has a top speed of 15.5mph (25 km/h), you can ride your electric bike on UK roads without having to buy insurance or obtain a license, etc.

It's essential to note that the 15.5 mph limit applies to electric assistance; riders can, of course, pedal faster than this speed without assistance.

How to Make Your E-bike Faster?

How to increase the speed of an e-bike without exceeding the top speed limit? Here are a few tips to make your electric bike faster.

1. Adjust pedal assist

If you're new to electric bikes, you might not know that the pedal assist on many e-bikes is adjustable - the higher the pedal assist, the more power the motor can allocate to your ride. So instead of pedaling harder to increase speed, you can also adjust the pedal assist level to increase the speed of your e-bike.

2. Fully charge the battery

A fully charged e-bike will always go faster than an e-bike with a low battery, because a weak e-bike cannot continuously provide enough power. Therefore, in order to ensure that the riding speed is not affected, it is recommended that you frequently check the power of the electric bicycle to ensure that the power is sufficient.

3. Increase tire pressure

Tire pressure is very important to the performance of your e-bike. When tire pressure is lower, the contact area between the tire and the ground is larger, resulting in slower speeds. So if you want to make your e-bike faster, then increase the tire pressure.


Fast electric bikes can effectively increase the speed of riding and make riding more efficient and convenient. However, while pursuing speed, you must pay attention to safety, at least your riding speed cannot exceed 15.5 mph or 25 km/h stipulated in British regulations, so that you can ride on different roads in the UK without restrictions. The 5 fast e-bikes in the UK mentioned above meet such requirements and allow you to enjoy speed while complying with regulations.
