UK EAPC rules: what a legal e-bike can do

A US Class 2 commuter is not an EAPC because the shop called it an e-bike. In Great Britain the legal product is narrower: 250 watts, assist that dies at 15.5 mph, and pedals that can actually move the bike.

This page is the UK brief we will use before we ever put a British shop on a shortlist. It is not legal advice. Northern Ireland and some local path rules can differ. Confirm on GOV.UK before you ride.

The 20-second version

To be treated as an electrically assisted pedal cycle (EAPC) in Great Britain you typically need all of this:

  • Pedals that can propel the bike
  • A motor of 250 watts continuous or less
  • Motor assistance that cuts out at 15.5 mph (25 km/h)
  • No throttle that drives the bike at road speed without pedaling (a walk-assist around 6 km/h is the usual exception)

If it meets the EAPC definition you do not register it, tax it, MOT it, or hold a motorcycle licence to ride it on public roads. That is the whole point of the category.

If it does not meet the definition, it is not “a fast e-bike.” It is a motor vehicle the DVLA and the police already have a box for.

EAPC is not Class 1 / 2 / 3

The US three-class sticker does not travel.

US labelTypical US assistEAPC?
Class 1Pedal assist to 20 mphNo — 20 mph is already over 15.5
Class 2Throttle to 20 mphNo
Class 3Pedal assist to 28 mphNo

A Velotric Discover set to 20 or 28 mph is a US commuter. Importing it to London and calling it an EAPC is how people buy a moped without the paperwork.

Our US shortlist is not a UK shortlist. Lankeleisi.fr is closer to the EU 25 km/h cap, but a French storefront is still not a UK retailer and not an automatic EAPC certificate.

Power: 250W continuous, not the Amazon peak

Listings love “1,000W peak.” EAPC language cares about the continuous 250W ceiling.

A motor that can be unlocked past 15.5 mph, or that is honestly 500–750W continuous, is outside the category even if the listing still says “electric bicycle.”

Throttle and walk mode

A throttle that pulls you to 15.5 mph without pedaling is the feature that turns a lot of imported “Class 2” bikes into vehicles. Walk mode at walking pace is the limited extra most riders can expect on a true EAPC.

If the seller’s demo video is throttle-only down a high street at 20 mph, you are not shopping for an EAPC.

Helmet, insurance, paths

EAPC riders are not required by the national EAPC rules to wear a helmet or to hold bike insurance. Paths, estates, and employers can still set their own rules. A forest trail can ban every motor. That is the same logic as the US page: the product rule is not the path rule.

How The Ride Brief will use this

We will not list a US Class 3 bike as a “UK commuter.” When we add a UK shop, the spec sheet must show 250W / 15.5 mph (or the retailer must sell a locked EAPC version). Until that checkout path exists, this page stays a law brief, not a shopping grid.

Read with: US e-bike classes (so you see the contrast), real-world range, commuter shortlist (US/EU only for now).

Check the current wording on GOV.UK: “Electric bikes: licensing, tax and insurance.” Statutes change; this brief tracks the EAPC idea, not every amendment date.
