The short answer
In Great Britain an electric bike is legal to ride like a pedal bike, with no licence, registration, tax or insurance, if it passes three tests: a motor rated at no more than 250W continuous, assistance that stops at 15.5mph, and pedals that drive it. You must be 14 or over, and you cannot ride it on the pavement (GOV.UK). Northern Ireland uses the same three numbers and the same minimum age (nidirect).
Fail any test and the law treats the bike as a motorcycle or moped: it must be registered, taxed and insured, you need a driving licence and a motorcycle helmet, and it can only go on the road. Since 29 June 2026 police in England and Wales no longer have to give a warning before seizing a motor vehicle used in an antisocial way.

The three numbers, and where they are written down
The legal name for a road-legal e-bike is an electrically assisted pedal cycle, or EAPC. GOV.UK sets out the tests:
- Power: the motor "must have a 'continuous rated power' output of no more than 250 watts".
- Speed: the motor "must not be able to propel the bike when it's travelling at more than 15.5 miles per hour". That is 25km/h, the figure most listings quote.
- Pedals: the bike must have pedals that can propel it. A bike that moves on the motor alone is in a different category (see throttles below).
The legal source is the Electrically Assisted Pedal Cycles Regulations 1983 as amended in 2015. The 2015 amendment set the limit as a "maximum continuous rated power which does not exceed 250 watts", raised the speed from 15 to 15.5, and removed the old weight limits (SI 2015/24).
"Continuous rated" matters. The test is the motor's continuous rating, not its peak, which is why a 250W-rated motor can still feel strong on a hill. A listing that gives its motor rating as 500W or 750W is describing a moped.
What must be marked on the bike
The markings must show the continuous rated power and the manufacturer, and either the battery's voltage or the maximum speed at which the motor assists (GOV.UK). If you cannot find these on the frame, ask the seller before you ride on a road.
Throttles and walk-assist
GOV.UK puts it plainly: an e-bike "can be propelled up to 15.5mph without pedalling but only if it's been approved". Approval "should have been done by the manufacturer or importer before you bought it", and an approved bike "will be marked with the approval number". If it has not been approved, the owner can apply for Motorcycle Single Vehicle Approval.
This is where most online listings go wrong. When we read the first 20 unsponsored Amazon UK listings for "folding electric bike" on 22 October 2026, 12 described a mode that moves the bike without pedalling, as a throttle or a "pure electric mode", and none mentioned approval (our folding e-bike audit). Three had "Unlockable Speed Limit" in the product title. In our earlier read of the top 20 general e-bike listings, 3 mentioned a throttle and none mentioned approval (our e-bike audit, 16 October 2026).
If your e-bike is not an EAPC, it is a moped in law
A bike that is more powerful than 250W, assists above 15.5mph, or runs without pedalling and has no approval, is treated as a motorcycle or moped. GOV.UK says you then need to:
- register and tax it, and insure it;
- hold a valid driving licence;
- wear a motorcycle helmet that meets British safety standards;
- ride it only on the road, not on cycle tracks or cycle lanes.
If you do not, "you may get a fine or your bike may be seized by the police" (GOV.UK).
What changed in 2026: seizure without a warning
Section 8 of the Crime and Policing Act 2026 changed police powers to seize motor vehicles "used in manner causing alarm, distress or annoyance". It repealed section 59(4) and (5) of the Police Reform Act 2002, which had made the power exercisable only after a warning (legislation.gov.uk). It applies in England and Wales and has been in force since 29 June 2026. The Home Office says it "will make it easier and quicker for police to seize vehicles being used anti-socially" (Home Office circular 004/2026).
Neither the Act nor the circular names e-bikes. The power covers motor vehicles, and GOV.UK treats an e-bike outside the EAPC rules as a motorcycle or moped, so the practical risk falls on non-compliant bikes. A legal EAPC is a pedal cycle in law.
On scale, Press Association freedom of information requests reported 7,049 e-bikes seized in the 12 months to 19 May 2026 by the 31 of 45 UK police forces that gave comparable figures, against 3,858 a year earlier (PA via Shropshire Star). That is news agency data, not an official statistic, and we have not found a Home Office or police source that publishes it.
Northern Ireland
nidirect sets the same limits: 250W maximum, no assistance above 15.5mph (25km/h), and a minimum age of 14. An EAPC needs no registration, licence or insurance there, and a bike that can be propelled without pedalling must be type approved (nidirect). The GB 2026 seizure change above applies in England and Wales only.
What did not change: 250W stays
The Department for Transport consulted on raising the power limit to 500W and on letting throttle-only e-bikes run without type approval. On 28 January 2025 it said "we will not take forward the proposals that were consulted upon", citing "a significant lack of evidence" (DfT consultation outcome). Anyone selling a more powerful bike as "about to be legal" is wrong as of 22 October 2026.
Conversion kits
The EAPC tests describe the finished bike, so a pedal bike converted with a kit has to meet the same 250W, 15.5mph and pedals tests to be ridden as a pedal cycle. Batteries for conversion kits are covered by the government's statutory guidelines on lithium-ion battery safety for e-bikes, which producers selling in Great Britain must take into account (OPSS). Fire risk is the bigger issue here: of 217 e-bike fires reported to the Office for Product Safety and Standards for 2025, 82 involved converted bikes (OPSS). See e-bike battery fire safety.
The questions that come up most
Do I need a licence or insurance for an e-bike? Not for an EAPC: GOV.UK says you do not need a licence, and it "does not need to be registered, taxed or insured". Insurance against theft or third-party claims is optional and often worth pricing.
Is a 750W e-bike legal in the UK? Not as a pedal cycle. Above 250W continuous it is a motorcycle or moped in law, with registration, tax, insurance, a licence and a motorcycle helmet.
What age can you ride an e-bike? 14 or over, in both Great Britain and Northern Ireland.
Can I ride an e-bike on the pavement? No. An EAPC can go on cycle paths and anywhere else pedal bikes are allowed, but not pavements.
Can I ride an e-bike if I am banned from driving? A legal EAPC needs no licence under GOV.UK's rules. A bike that is not an EAPC needs a licence, so a disqualified rider cannot legally use one on the road. Take advice for your own case.
Do I need lights? The lighting rules for pedal cycles apply after dark. Our bike lights guide covers the Highway Code rule, including the reflectors most sets leave out.
Is a private e-scooter the same? No. GOV.UK says "it is against the law to use a privately owned electric scooter on public land". See e-bike vs e-scooter.
Before you buy: five checks
- Does the listing state 250W continuous, not a peak figure or nothing?
- Does it state assistance stops at 15.5mph or 25km/h?
- Does it describe a throttle, "pure electric" or "electric mode"? If so, is there an approval number?
- Does it advertise an unlockable or adjustable speed limit? If so, walk away.
- Will the frame carry the markings: power, maker, and voltage or top assisted speed?
Our best electric bikes guide and best folding electric bikes guide only pick listings that state 250W and leave out any that advertise an unapproved no-pedal mode or an unlockable speed. Where a pick does not state the cut-off speed, the guide says so.
