E-bike 250W stickers and why the fake ones don’t work

May 6, 2026

e-bike 250W sticker

In a market flooded with imports and retrofit kits, it can be difficult to identify a road-legal e‑bike. It’s why manufacturers are required to attach a sticker or plate to every e‑bike frame, indicating whether it complies with EAPC (sometimes written as EPAC) standards. EAPC stands for Electric Assist Pedal Cycle: a set of regulations that allows an e‑bike to be treated the same as a conventional bicycle in the eyes of the law.

In the UK and EU, official guidance says the e-bike must be clearly marked with the manufacturer’s name and the motor’s continuous rated power output, along with either the battery voltage or the maximum assisted speed. 

It would be simpler if EAPC‑compliant e‑bikes displayed a universally recognised symbol. As it stands, you have to find the small sticker or plate and pick out the relevant information from among other specifications, such as the date of manufacture or maximum laden weight.

Why fake 250W e-bike stickers don’t work

Online marketplaces even sell fake e‑bike stickers for owners of overpowered machines that exceed the 250W and 15.5mph limits and should be registered as mopeds or motorcycles.

In practice, these stickers are unlikely to fool the police. As part of a crackdown on illegal e‑bikes, officers now use compact roadside dynos that can measure an e‑bike’s assisted top speed on the spot. This does away with the need to send bikes away for testing.

Any e-bike with a motor bigger than 250W, or an assisted speed over 25km/h is a moped or motorbike. Failure to register an overpowered e-bike can result in seizure, a £300 fine and six penalty points on your driving licence. For under-18s, penalty points accumulated before they obtain a full driving licence carry over, potentially leading to an automatic ban under the New Drivers Act.

If the police seize your e-bike, they are likely to use either a Section 59 (anti-social use, inconsiderate riding on the road, off-road riding without permission, causing or likely to cause alarm, distress or annoyance), or a Section 165A if officers believe the vehicle’s being used without insurance or the correct licence.
