What is an E-Bike Under UK Law?

In the UK, an e-bike is defined as an electrically-assisted pedal cycle (EAPC). To qualify as an EAPC, the bike must:

• Have pedals that can propel it.
• Limit power assistance to a maximum speed of 15.5 mph (25 km/h).
• Have a motor that does not exceed 250 watts of continuous power output.

If an electric bike meets these criteria, it’s classified as an EAPC and can be legally ridden without a license, insurance, or vehicle registration. E-bikes that exceed these specifications are considered motor vehicles and require registration, a driver’s license, insurance, and tax.

Throttle Regulations on E-Bikes in the UK

In the UK, throttle use on e-bikes is strictly regulated. EAPCs are allowed to have a throttle that assists the bike without pedaling, but only up to a speed of 6 km/h (3.7 mph), typically to help riders start from a stationary position. Beyond this speed, the motor must only provide assistance when the rider is actively pedaling, up to the maximum allowed 15.5 mph (25 km/h).

If an e-bike has a "twist and go" throttle that can propel the bike without any pedaling at speeds above 6 km/h, it no longer qualifies as an EAPC. Instead, it must be type-approved, licensed, registered, and insured, similar to a moped or motorcycle.

Age Requirements for E-Bike Riders in the UK

To ride an EAPC in the UK, the rider must be at least 14 years old. This applies to all areas, including public roads, bike lanes, and shared paths.

Speed Limits and Motor Assistance

The 15.5 mph (25 km/h) speed limit for motor assistance ensures that e-bikes remain safe for public use. Although you can pedal beyond this speed, the motor must stop providing assistance once this limit is reached.

Where Can You Ride an E-Bike in the UK?

In the UK, e-bikes classified as EAPCs are allowed in most areas where traditional bicycles are permitted:

• Public roads
• Cycle lanes
• Shared pathways designated for bicycle use

However, be cautious in areas where bicycles are restricted, such as motorways and certain pedestrian-only paths.

Safety Equipment and Helmets

While helmets are not legally required for e-bike riders, they are highly recommended. Reflective gear and lights are also advisable, especially for low-light riding. UK law mandates front and rear lights for bikes after dark.

Insurance for E-Bikes

Insurance is not required for EAPCs in the UK. However, optional e-bike insurance can offer protection against theft, damage, and third-party liability, providing peace of mind for frequent riders.
