Disclaimer: Electric Bike Speed and Throttle Use in the UK

The use of electric bikes (e-bikes) in the UK is regulated by specific laws regarding speed, motor assistance, and throttle functionality. This disclaimer outlines key information to ensure compliance with UK regulations.

1. Maximum Speed Limit for Motor Assistance

  • The motor on an e-bike must stop providing assistance once the bicycle reaches 15.5 mph (25 km/h).
  • Riders can pedal faster than this speed, but the motor must not contribute further propulsion.

2. Motor Power Restrictions

  • The motor's maximum continuous power output must not exceed 250 watts.
  • Any bike with a more powerful motor or a higher assistance speed is classified as a motor vehicle and subject to licensing, insurance, and registration.

3. Throttle Use

  • "Twist-and-Go" Throttles:
    • Throttles that allow the bike to accelerate without pedalling are restricted.
    • These bikes must comply with "Type Approval" regulations, meaning they are treated similarly to mopeds or motorcycles under UK law.
  • Pedal-Assist Throttles:
    • Throttles that only function when pedalling are legal, provided they conform to speed and power limits.
    • These are commonly found on standard e-bikes and are exempt from additional requirements.

4. Non-Compliant E-Bikes

  • E-bikes that exceed the legal speed or use unrestricted throttles fall under motor vehicle laws and require:
    • A valid driver's license.
    • Vehicle registration and insurance.
    • Adherence to additional safety and operational regulations.

5. Penalties for Non-Compliance

  • Using a non-compliant e-bike on public roads without proper licensing or registration may result in fines, penalties, or the bike being impounded.
