E-bike law

E-bike laws in the UK

An e-bike rides like a pedal bike in the UK only if it meets the electrically assisted pedal cycle (EAPC) rules. Anything else is, in law, a moped or a motorcycle.

This page explains the rules in plain English and is not legal advice. Laws change and local rules can be stricter, so check the official source for where you ride before you buy or ride.

In short

  • An EAPC must have pedals that can propel it, a motor of no more than 250 W continuous rated power, and no motor assistance above 15.5 mph (25 km/h). GOV.UK 1GOV.UK 2SI 2015/24
  • You can ride one from 14, with no licence, registration, tax or insurance, on cycle paths and anywhere else pedal bikes are allowed, but not on pavements. GOV.UK 1
  • A throttle that moves the bike without pedalling is allowed only up to 6 km/h (3.7 mph). Beyond that the bike needs type approval. GOV.UK 2GOV.UK 5
  • The government consulted in 2024 on a 500 W limit and on throttles up to 15.5 mph, and said it will not take the proposals forward. GOV.UK 6

What counts as a bicycle

The class here: Electrically assisted pedal cycle (EAPC). An e-bike rides like a bicycle only if it stays inside every limit below.

RuleLimitWhat the law says
Motor power250 W continuous ratedThe motor's continuous rated power must not exceed 250 W. GOV.UK 1SI 2015/24
Assisted speed15.5 mph (25 km/h)The motor must not be able to propel the bike when it is travelling faster than 15.5 mph (25 km/h). GOV.UK 1SI 2015/24
ThrottleTo 6 km/h (3.7 mph) onlyPower without pedalling is exempt from type approval only up to 6 km/h (3.7 mph), to help you start. A 'twist and go' bike that goes faster on the throttle must be type approved, or individually approved as a 250 W low-powered moped. GOV.UK 5GOV.UK 2
Minimum age14You must be 14 or over to ride an EAPC. GOV.UK 1
HelmetAdvised, not part of the EAPC rulesHighway Code rule 59 advises cyclists to wear a cycle helmet that conforms to current regulations, fits and is fastened. Highway CodeOn a bike that fails the EAPC rules, a motorcycle helmet is required. GOV.UK 1
Licence, registration, insuranceNoneNo licence, and the bike does not need to be registered, taxed or insured. GOV.UK 1

What falls outside the bicycle class

  • Motor assistance above 15.5 mph, continuous rated power above 250 W, or no pedals that can propel it: the bike is not an EAPC. GOV.UK 2
  • Such a bike is classed as a motorcycle or moped. It must be registered, taxed and insured, and you need a driving licence and a motorcycle helmet to ride it. GOV.UK 1GOV.UK 2
  • 'Twist and go' e-bikes placed on the market or entering into service after 1 January 2016 have to meet technical requirements, typically shown by type approval, before they can be used on the road. Walk assist that stays at or below 3.7 mph (6 km/h) is outside type approval. GOV.UK 2
  • A bike with an 'off road' mode that lets the motor propel it above 15.5 mph does not, in the Department for Transport's view, comply with the EAPC rules, and is treated as a motor vehicle. GOV.UK 2

Where the rules vary

Only the regions we checked against an official source are listed here. Rules elsewhere can differ.

Northern Ireland

  • The same limits apply: 250 W, no assistance above 15.5 mph (25 km/h), and riders aged 14 or over. An EAPC does not need to be registered, licensed or insured, and the rider does not need a driving licence. nidirect
  • Northern Ireland has its own regulations for this: the Electrically Assisted Pedal Cycles (Construction and Use) Regulations (Northern Ireland) 2020. NISR 2020/31

Recent and coming changes

  • 2024 to 2025The Department for Transport consulted in 2024 on two changes: raising the limit to 500 W, and allowing throttles up to 15.5 mph (25 km/h) without type approval. Its published outcome says it will not take the proposals forward, so the 250 W and 15.5 mph rules stand. GOV.UK 5GOV.UK 6

Background

What the bike must be marked with

Markings on the bike must show the continuous rated power output and the manufacturer, and either the battery voltage or the maximum speed the motor can propel the bike. GOV.UK 1

Where the rules come from

The definition is in the Electrically Assisted Pedal Cycles Regulations 1983, amended in 2015 to the current 250 W and 15.5 mph figures. SI 1983/1168SI 2015/24

Under assimilated EU Regulation 168/2013, throttle assistance above 6 km/h (3.73 mph) requires type approval. GOV.UK 5

What this means when buying

230 bikes in our catalogue are listed as sold in the United Kingdom. By the figures we hold, 184 are within the bicycle-class limits, 46 are over them, and 0 lack the data to say.

How we count

We compare each bike's listed top speed, and its throttle and fast-class flags, with the class above: a listed speed over 15.5 mph (25 km/h) counts as over the limit. A throttle counts as not enough data, because a listing does not say whether it stops at 6 km/h. We do not hold rated motor power for every bike yet, so a bike within the limit on speed can still be over it on power. Where a store listed no top speed, our importer recorded 25 km/h, so a bike listed at exactly 25 km/h is weaker evidence than it looks.

A listing is not a legal classification. Check the label on the bike and the rules where you ride.

Questions people ask

Is a 500 W e-bike legal on UK roads?

Not as an EAPC: the limit is 250 W continuous rated power. A bike over it is treated as a moped or motorcycle, with registration, tax, insurance, a licence and a motorcycle helmet. The government consulted on 500 W in 2024 and said it will not take the change forward. GOV.UK 1GOV.UK 6

Can a UK e-bike have a throttle?

Only for start-up help up to 6 km/h (3.7 mph) without type approval. A 'twist and go' bike that goes faster without pedalling must be type approved, or individually approved as a 250 W low-powered moped. GOV.UK 5GOV.UK 2
