E-bike rules: is my e-bike legal?

E-bike laws in the UK: the EAPC rules

In England, Scotland and Wales an electrically assisted pedal cycle (EAPC) is treated like a bicycle. As GOV.UK set the rules out on 5 November 2026:

• It must have pedals that can be used to propel it.
• The motor’s continuous rated power must be no more than 250 W, and it must not be able to propel the bike above 15.5 mph. Those figures came in with the 2015 amendment to the EAPC Regulations 1983 (in force from 6 April 2015).
• The bike must show its power output and maker, and either the battery voltage or the top assisted speed.
• A bike that can be propelled without pedalling (a “twist and go” throttle) is only allowed if it has been approved.
• You must be 14 or over. You don’t need a licence, and the bike doesn’t need to be registered, taxed or insured. You can use cycle paths and anywhere else bikes are allowed, but not pavements.

A bike that breaks any of these rules is classed as a motorcycle or moped. It has to be registered, taxed and insured, you need a driving licence and a motorcycle helmet, and it can only be ridden on the road, not in cycle lanes or on cycle tracks. Without insurance, the police can fine you or seize the bike. Northern Ireland has its own rules, which this page doesn’t cover.

E-bike classes explained (US)

The US three-class system started as model legislation published by the US cycling organisation PeopleForBikes (our copy is dated January 2020). It’s a template that states adapt, not a law in itself. In the model, an electric bicycle has fully operable pedals, a saddle and a motor of less than 750 W, and falls into one of three classes:

Class	How the motor helps	Assistance stops at
Class 1	Only while you pedal	20 mph (32 km/h)
Class 2	Can propel the bike alone (throttle)	20 mph (32 km/h)
Class 3	Only while you pedal	28 mph (45 km/h)

The model also asks for a label showing the class, top assisted speed and motor wattage, bans tampering that changes the speed or engagement unless the label is changed, and for class 3 sets a minimum age of 16, a helmet and a speedometer. Each state’s statute is what actually applies, and they differ. Two examples:

• New York (Vehicle and Traffic Law § 102-c): under 750 W, no more than 36 inches wide, with operable pedals. Classes 1 and 2 stop at 20 mph, but class 3 may use a throttle and assists to 25 mph, and only within a city of a million people or more, which means New York City.
• Washington (RCW 46.04.169): a motor of no more than 750 W, classes 1–3 as in the model, class 3 with a speedometer. Bikes that can exceed 20 mph on the motor alone are excluded. Class 3 bikes may not use shared-use paths unless the local authority allows it (RCW 46.61.710).

Separately, federal product-safety law (15 U.S.C. § 2085) defines a “low-speed electric bicycle” as one with fully operable pedals, a motor under 750 W and a top speed under 20 mph on the motor alone (with a 170 lb rider). That definition decides which product rules a bike is sold under; road rules are still up to each state.

EU: where an e-bike ends and a moped begins

EU Regulation 168/2013 sets the type-approval rules for light motor vehicles. Article 2(2)(h) leaves out pedal cycles whose motor has a maximum continuous rated power of 250 W or less, cuts out when you stop pedalling, and is progressively reduced and cut off before 25 km/h. Those are ordinary e-bikes. Anything more powerful or faster falls into the regulation: a “powered cycle” (L1e-A) has pedal assistance up to 1,000 W cut off by 25 km/h, and a two-wheel moped (L1e-B) goes up to 4,000 W and 45 km/h. Both need type approval. Each country’s road rules then decide where and how they may be ridden.

Is my e-bike legal? How to check

1. Find the label or plate on the frame. Note the continuous rated power (the peak power in an advert is a different, bigger number) and the top assisted speed.
2. Check how the motor responds: does it help only while you pedal, or will it move the bike when you press a button or twist a grip?
3. Enter the figures in the checker, then follow the source link for your country or state.

De-restricted and modified e-bikes

“De-restricting” an e-bike (with a chip, a dongle or settings that lift the assistance limit), or fitting a stronger motor, changes what it is in law. In Great Britain it stops being an EAPC and becomes a moped or motorcycle, with registration, tax, insurance, a licence and a motorcycle helmet, and it’s banned from cycle lanes and tracks. The US model law forbids tampering that changes the speed or engagement of the motor unless the class label is changed too. London Fire Brigade also warns that conversion kits can increase the risk of battery fires if they’re poorly installed or use incompatible parts.

Battery and charging safety

London Fire Brigade says that, on average, there’s a fire from a lithium-ion battery in an e-bike or e-scooter every two days in London (its e-bike safety page, checked 5 November 2026), and that these fires spread rapidly and give off toxic smoke. Official advice from the Brigade and from the US Consumer Product Safety Commission (CPSC) comes down to a few habits:

• Buy from reputable retailers or manufacturers. Be wary of unusually low prices, missing CE or UKCA markings and counterfeit labels, and second-hand or damaged batteries.
• Charge only with the charger provided or recommended by the manufacturer.
• Be there while it charges. The CPSC says never to charge while you’re asleep or out of the house.

If there’s an e-bike under the tree on Friday 25 December 2026, read its label before the first ride: in Great Britain the rider must be at least 14. Then set its tire pressure for the extra weight, and check the bike lights law for dark commutes.

Common mistakes

• Reading the peak power. The laws use continuous rated power; adverts often quote a bigger peak.
• Assuming US classes apply everywhere. A class 2 throttle bike legal in Washington needs approval in Great Britain.
• Treating a 25 km/h EU e-bike and a 28 mph class 3 bike as the same thing. The second is a motor vehicle in Great Britain and far outside the e-bike exclusion in the EU.
• Charging overnight. The CPSC says never to charge while you’re asleep or away from home.
