Staying on the Right Side of the Law
In the UK, an EAPC (Electrically Assisted Pedal Cycle) must meet specific criteria to be treated as a normal bicycle. If it does not meet these, it is legally a moped.
What is Legal?
- Motor power maximum of 250 Watts.
- Assistance must stop at 15.5 mph (25 km/h).
- You must be over 14 years old to ride one.
The Danger of Tuning Kits
Fitting a "dongle" or tuning kit to make your bike go faster than 15.5 mph is illegal for road use. It can lead to points on your driving licence, a fine, and the seizure of your bike. It also voids your warranty and insurance.
