UK e-bike legality checker
Is this bike legal to ride on a UK road? Enter the figures from the listing and find out in one step — including whether it can ever be made legal.
The four tests this applies
An Electrically Assisted Pedal Cycle, the only kind of electric bike you can ride on a UK public road without registering it, must meet all of these:
- Motor rated at no more than 250W continuous. Not peak power: the continuous rating. A 250W motor peaking at 600W on a climb is fine.
- Assistance cuts out at 15.5 mph (25 km/h). Above that speed the motor must stop helping, though you can still pedal faster yourself.
- Pedals, and assistance only when pedalling. The motor helps you pedal; it does not replace pedalling.
- No throttle above 6 km/h (3.7 mph). A walk-along throttle is allowed up to that speed. A twist-and-go throttle that propels the bike to 15 mph without pedalling makes it a motor vehicle.
There is also an age rule: the rider must be at least 14 to use an EAPC on a public road.
What "motor vehicle" means in practice
If the bike fails any of those tests, it is a moped or a motorcycle in law, whatever the listing calls it. To use it on a public road you would need type approval for the machine, DVLA registration and a number plate, vehicle tax, motor insurance, the right licence category (AM for a moped, A1/A2/A for a motorcycle) and an approved motorcycle helmet.
The killer is usually type approval. Most high-power imports do not have it and cannot obtain it, so the sequence stops at the first step and the machine cannot be made road-legal at all. It can still be used on private land with the landowner's permission, which is a real and legitimate use — it is just not a commute.
What to do with the answer
If the checker says the bike is legal, nothing else is needed: no licence, no registration, no tax, no MOT, no compulsory insurance and no helmet law for adults. Optional insurance is still sensible, and our guide to licence, insurance and helmets explains what a policy will ask you.
If it says motor vehicle, decide honestly whether you are buying a road vehicle or a toy for a field. If it is the road, buy a 250W bike instead — no discount on a 1000W machine compensates for not being able to use it legally.
Why we publish this
We list a wide catalogue, and part of it is not legal on UK roads. Rather than quietly omitting that, or implying everything is fine, we would rather you knew before you spent the money. The full guide to UK e-bike law covers the detail, and the guide to e-scooters and e-moto bikes covers the categories that are never road-legal.
