E-bike law in the UK: what makes an electric bike legal (2026)

Short answer: in the UK an e-bike is treated like an ordinary bicycle if it is an “electrically assisted pedal cycle” (EAPC). You can ride one from age 14, and you do not need a licence, registration, tax or insurance. If the bike does not meet the EAPC rules, the law treats it as a moped or motorcycle.

What makes an e-bike an EAPC

All of these must be true:

• Pedals that can propel the bike. It can have more than two wheels, so many e-trikes qualify.
• A motor with a continuous rated power of no more than 250 W. Rated power is not the same as peak power: plenty of legal bikes list “250 W rated, 600 W peak”. Only the rated figure counts.
• Assistance that stops at 15.5 mph (25 km/h). The motor must not be able to push the bike any faster.
• Markings on the bike showing the rated power and the maker, plus either the battery voltage or the top assisted speed.

Throttles and “twist and go” e-bikes

A bike whose motor can move it up to 15.5 mph without you pedalling (a “twist and go”) must be approved before it can be used on the road. The maker or importer should have done this before the bike was sold, and an approved bike carries an approval number. If it has none, the owner can apply for a Motorcycle Single Vehicle Approval (MSVA).

Many throttle e-bikes sold online across Europe are not approved. In the UK those count as mopeds. The government consulted on allowing 500 W motors and throttles, but dropped the plans in January 2025.

The same goes for “unlock” or “off-road” modes. If the motor can assist above 15.5 mph, the bike is not an EAPC in that mode.

Where you can ride an EAPC

On roads, cycle lanes, cycle tracks and anywhere else bicycles are allowed. Not on pavements, and not on motorways. A helmet is recommended but not required.

If your e-bike is not an EAPC

An e-bike with more than 250 W rated, assistance above 15.5 mph or an unapproved throttle is a moped or motorcycle. To ride it legally you need:

• vehicle approval, registration and road tax;
• motor insurance;
• a licence: AM for mopeds (learners need CBT, a provisional licence and L plates);
• a motorcycle helmet that meets British standards.

It can only be ridden on the road, not on cycle tracks or in cycle lanes. Riding one without insurance usually means a £300 fixed penalty and 6 penalty points, and the police can seize it. Since 29 June 2026 police in England and Wales can also seize vehicles ridden antisocially without a prior warning.

Speed pedelecs, which assist up to 45 km/h, have no category of their own in the UK. They follow the moped rules above.

Fines for dangerous cycling

The rules for riders apply to EAPCs as they do to any bicycle. Dangerous cycling carries a fine of up to £2,500 and careless cycling up to £1,000. The Crime and Policing Act 2026 adds new offences, such as causing death by dangerous cycling, with sentences up to life imprisonment. On 9 November 2026 they were not yet in force.

Northern Ireland

The same EAPC rules apply, with the same minimum age of 14.

Checking a bike before you buy

1. Find the rated motor power, not just the peak.
2. Ask whether the throttle works without pedalling, and up to what speed. If it moves the bike up to 15.5 mph by itself, ask for the approval number.
3. Check for unlock modes or “private land” settings in the manual.

Every e-bike page on RideZoom shows a UK verdict for the bike as sold, with the reasons. For example, the Fiido C21 is a standard EAPC, while the DYU C6 has a throttle and counts as a moped.
