Throttle and public-road use in Great Britain
A 250W label or 25km/h setting alone does not establish EAPC compliance. The complete cycle must have usable pedals, no more than 250W maximum continuous rated motor power, an assistance cut-off at 15.5mph, and the required markings and safety equipment. Walk assist limited to 3.7mph (about 6km/h) is outside the throttle type-approval requirement. A twist-and-go cycle introduced after 1 January 2016 that can propel itself without pedalling beyond walk-assist speed requires type approval or individual approval, even if it meets the EAPC power and speed limits. An approved twist-and-go EAPC can still be treated as a pedal cycle; a throttle does not automatically make every bike unlawful.
Using pedal assist, avoiding the throttle or choosing a lower display setting does not establish compliance. Department for Transport guidance also treats cycles with a selectable mode capable of motor propulsion above 15.5mph as motor vehicles. Where the supplied configuration or required approval has not been verified, do not use the bike on public roads or cycle paths as an ordinary EAPC. Use only on suitable private land with permission unless the applicable road-use requirements are met. Read the official EAPC and throttle guidance.
If you're buying an electric bike in the UK, the single most important thing to understand before you ride is whether it counts as an EAPC — an Electrically Assisted Pedal Cycle. Get this right and you can ride on the road and cycle paths like any other bicycle, with no licence, insurance, registration or age restriction beyond 14. Get it wrong, and you could be riding what the law treats as a motor vehicle without the paperwork to go with it.
What counts as an EAPC?
To qualify as an EAPC under UK law, an electric bike must meet all of the following:
- Pedals that can be used to propel it
- An electric motor with a maximum continuous rated power of 250W
- Motor assistance that cuts out once the bike reaches 15.5mph (25km/h)
- A label showing the motor's power output and the bike's top assisted speed (or the manufacturer/importer's details)
If a bike meets all four points, it's treated the same as a regular pedal bicycle. You don't need a licence, number plate, insurance or MOT, and there's no minimum age beyond 14 to ride one on a public road.
What happens if a bike exceeds these limits?
A cycle exceeding the 250W maximum continuous motor rating or 15.5mph assistance limit does not qualify as an ordinary EAPC. Throttle propulsion beyond walk-assist speed is a separate approval question: a properly approved twist-and-go cycle can remain an EAPC if it meets the other requirements. A non-EAPC is treated as a motor vehicle for public-road use.
Electric dirt bikes and high-power fat tyre bikes
Electric dirt bikes and performance fat tyre bikes with motors well above 250W (some of the models we stock go up to 3500W) are enormous fun, but they are not EAPCs and are not legal to ride on public roads, pavements or bridleways in the UK. They're intended for private land with the landowner's permission, or licensed off-road riding sites. Always check the specific product listing — check each bike's exact supplied specification and any required approval; a 250W collection label is not certification of road legality.
Where can a road-legal EAPC be ridden?
A compliant EAPC can go anywhere a normal pedal bike can: on the road, in cycle lanes, and on bridleways or byways where cycling is permitted. It cannot be ridden on footpaths that exclude cyclists, or anywhere ordinary bicycles aren't allowed.
Adjustable or "derestricted" e-bikes
A selectable mode capable of motor propulsion above 15.5mph affects the cycle's classification even if the rider leaves it unused. Department for Transport guidance treats cycles with such an off-road mode as motor vehicles. Keeping a display in a lower setting does not establish EAPC compliance.
Quick checklist before you buy
- Do you need the bike for road commuting, or off-road riding on private land?
- If it's for the road, confirm the listing states UK road legal / EAPC compliant
- If it's a higher-power or dirt bike model, plan where you'll actually be allowed to ride it
- Check the manufacturer's label for motor power and assisted top speed
