How Fast Can an Electric Bike Go?

Electric bikes are revolutionising our commutes and leisure rides to explore at the weekend. The pedal power blended with electric help caters to riders not up for the expense of a motor car or motorcycle. Electric pedal bikes are catching on as a reliable, green, and fun option!

This blog delves into how fast electric bikes are allowed to go in the UK, what makes an e-bike faster, and the safety of riding at top speed.

What Is the Top Speed of an E-Bike in the UK?

The ebike speed limit in the UK is set by the law. UK regulations categorise electric pedal bikes as Electrically Assisted Pedal Cycles (EAPCs). An EAPC is not a motor vehicle, so it must not exceed 15.5 mph with the electric motor pedal assist. Above 15.5 mph, the motor cuts off. Then, the rider pedals manually to go faster.

The speed limit ensures electric cycle riders are safe. Plus, riding is accessible for all riders without a licence, insurance, or registration. While the motor assist tops out at 15.5 mph, you can still go faster by pedalling harder. Your e-bike’s top speed comes from your own pedal power, with no help from the motor.

What Factors Affect the Speed of an E-Bike?

The legal speed limit is most important when it comes to the speed of an e-bike. Other elements influence how fast your e-bike can go. The motor power, battery capacity, terrain, rider weight, pedalling input, and wind conditions all add up.

Motor Power

At the heart of your e-bike’s speed is the power of the motor. In the UK, e-bike motors are limited to a maximum power output of 250 watts. This is enough help for most riders on most trails. It’s brilliant on flat terrain. It all goes back to the 15.5 mph speed limit.

The fastest ebikes with higher power motors from other countries have more torque and acceleration. Still, they are not legal on public roads in the UK.

Battery Capacity

Larger battery capacity gives the motor consistent power over longer distances and times. However, even when a bigger battery sustains motor assistance for longer, it doesn’t always increase the top speed.

Instead, the battery capacity makes more of a difference in the range and how long the e-bike offers higher assistance levels.

Terrain

The terrain makes a big difference to your electric cycle’s speed. Keeping up a steady speed on a flat, even surface is fairly easy. The motor effortlessly assists you up to the legal limit. However, riding uphill makes the motor work harder, reducing the speed on steeper inclines.

On the other hand, riding downhill increases speed as gravity takes over. In situations beyond the motor-assisted speed limit, exercise caution to maintain control and follow safety guidelines.

Rider Weight

The weight your ebike carries changes how fast it goes. Heavier riders take more power to get to and keep up the same speed as lighter riders. You will notice this the most when starting from a stop or climbing a hill.

The motor will help, but the extra load reduces the speed and efficiency of the e-bike. When you carry cargo or equipment, this also impacts speed and performance.

Pedalling Input

The idea of an electric pedal bike is that the motor helps you while you pedal. The more you pedal, the faster you go. That’s especially true once the motor reaches the assistance limit.

A fit rider can exceed the 15.5 mph speed limit on flatter terrains by doing more pedalling. You can choose between a leisurely ride when knackered or a more energetic cycling session.

Wind Conditions

Riding against a strong headwind might well slow you down, but only a little. On the other hand, a tailwind might feel like it helps you go faster. Wind conditions can impact speed and battery life.On windy days, plan for a slower ride and conserve battery power when you can.

Can You Ride an Electric Bike Without a Licence in the UK?

Yes. You can ride an electric pedal bike without a licence in the UK if it is an EAPC. The motor cannot have a maximum power output over 250 watts. The motor must stay under the 15.5 mph speed limit when helping with pedalling.

E-bikes are regulated like regular bicycles. You don’t need a licence, insurance, or vehicle registration for public roads and cycle paths.

Is It Safe to Ride an Electric Bike at High Speeds?

Speed is always an issue for safety. Electric pedal bikes are safe and stable under the speed limit. If you exceed this speed, even under your own power, there are risks.

• You need to react quicker at higher speeds.
• You need longer braking distances.
• Proper safety gear is essential.
• Regular maintenance is important. Check the brakes, tyres, and battery regularly.

Final Thoughts

Speed limits of electric pedal bikes in the UK are modest. Motor power, battery capacity, terrain, rider weight, pedalling input, and wind conditions all influence how fast you can go on an electric cycle.

Remember to ride within legal limits and always prioritise safety, especially at higher speeds. Explore the range of e-bikes at HeyBike for great e-bike options that comply with UK regulations.
