Electric bikes

Are electric bikes legal in the UK?

Most electric bikes sold by mainstream brands in the UK are road legal as they come. The ones that cause trouble are converted, imported or modified, and from the pavement they look much the same. Here is the line the law actually draws, and how to check which side of it a second-hand bike sits on.

The short answer

An electric bike is legal to ride on UK roads and cycle paths, with no licence, tax or insurance needed, if it meets the rules for an electrically assisted pedal cycle (EAPC): a motor with a continuous rated power output of no more than 250 watts, motor assistance that stops at 15.5mph, pedals that can be used to propel it, and a rider aged 14 or over. An electric bike that misses any of those is legally a motorcycle, and using it on the road without registration, tax, insurance, a driving licence and a motorcycle helmet is an offence.

The test

Four conditions, all of which have to be met

Meet all four and the bike is an electrically assisted pedal cycle, treated in law as a bicycle. Miss any one of them and it is not, however close it gets.

  1. 01

    A motor rated at 250 watts or less

    The figure that matters is continuous rated power, not peak output. A motor sold as “250W nominal, 700W peak” can still be compliant, because peak is a burst rating. A motor rated at 500W or 1000W continuous is not compliant, no matter what a switchable “road mode” claims on the listing.

  2. 02

    Assistance that cuts out at 15.5mph

    The motor must not be able to propel the bike when it is travelling faster than 15.5mph. You are free to pedal faster than that under your own power. The motor simply stops helping once you reach it.

  3. 03

    Pedals that can propel it

    It must have pedals that can be used to drive the bike. A machine that only moves under power is not a bicycle in law, whatever it looks like from across the street.

  4. 04

    A rider aged 14 or over

    You can ride an electric bike on the road if you are 14 or over. There is no upper age limit, no licence and no test.

What changes if it does not qualify

An electric bike that falls outside the rules is not simply a bike with a technical problem. It is a different class of vehicle, with everything that follows from that.

Meets the rules

Treated as a pedal cycle

  • No licence, registration, tax or insurance needed.
  • Ride it on cycle paths and anywhere else pedal bikes are allowed.
  • No helmet requirement in law, though one is sensible.
  • Not on pavements.

Does not meet the rules

Treated as a motorcycle or moped

  • Must be registered and taxed to use on the road.
  • You need a valid driving licence.
  • You must wear a motorcycle helmet meeting British safety standards.
  • It must be insured.
  • Road only. No cycle tracks, no cycle lanes.

In practice most converted or over-powered electric bikes cannot realistically be registered as motor vehicles at all, so the honest position is that they are for private land with the landowner’s permission. That is a legitimate thing to own and a legitimate thing to sell. It is not a legitimate thing to describe as road legal.

The throttle question

This is the detail most often got wrong, including by people selling e-bikes. gov.uk states that an electric bike can be propelled up to 15.5mph without pedalling only if it has been approved, and gives twist-and-go as the example of the kind of bike that needs that approval.

So a throttle is not automatically fatal, but it is not a free feature either. A bike can have a 250 watt motor and a correct 15.5mph cut-off and still sit outside the rules because of how the throttle works. If a used listing advertises one, that is a question to settle before you travel to see the bike, not a bonus to be pleased about.

You will find confident claims online about throttles being fine on anything built before a particular date. We have left those out deliberately, because gov.uk does not say it and we are not going to restate a rule we cannot source.

Before you buy

Checking a second-hand electric bike

A private seller is not required to know the law, and plenty do not. These are the questions that separate a compliant bike from one you will regret, and all of them can be asked before you get in the car.

  • Find the label before you find the bike

    An EAPC has to carry markings showing the continuous rated power output and the manufacturer, plus either the battery voltage or the maximum speed the motor can propel the bike. Ask the seller to photograph it. A label that has been peeled off, painted over or was never there is a reason to ask more questions, not fewer.

  • Read the motor rating, not the marketing

    Listings quote whichever number sounds best. Get the continuous rated figure in writing. If a seller can only tell you the peak, or answers in miles per hour rather than watts, they may not know what they are selling.

  • Ask directly whether it has a throttle

    A throttle that moves the bike without pedalling is the most common thing that quietly takes an otherwise sensible e-bike outside the rules. It is worth one plain question before you travel to see it.

  • Treat a conversion kit as a question

    A retro-fitted motor on an ordinary frame is the usual route to a non-compliant bike, because the kit’s rating and the cut-off are whatever the fitter chose. Ask which kit, what it is rated at, and who fitted it.

  • Be wary of “derestricted”, “unlocked”, “tuned” or “dongle”

    These words are sometimes used as selling points. They describe a bike that can be made to assist beyond 15.5mph, and while it is in that state it is not an EAPC. A bike advertised as switchable is still a bike that switches.

  • Check the frame number while you are at it

    Legality and provenance are separate questions with the same answer time. Run the frame number through a stolen-bike register before you hand over money.

  • Keep the answers in writing

    Ask through the platform’s messages rather than on the phone. If the bike later turns out not to be what you were told, a written description is worth considerably more than a recollection.

Sellers on Cyclesite can declare whether an electric bike is road legal, and where they have, it appears on the listing. Where they have not, ask. A seller who is happy to answer is telling you something useful either way. Check the frame number while you are asking.

Why this is worth an hour of your attention

Enforcement has changed sharply through 2026, and it is cutting in both directions.

  • The Metropolitan Police seized more than 2,500 illegal e-bikes and e-scooters in the first seven months of 2026, passing the 2,241 seized in the whole of 2025.

    Police Professional
  • YouGov polling for the Bicycle Association and the Association of Cycle Traders found 84% of people were not confident they could tell a legal electric bike from one that has been illegally altered.

    BikeBiz
  • West Midlands Police seized and destroyed a road-legal Tern cargo bike, then accepted the roadside test its officers used was not accurate, dropped the prosecution and agreed to pay compensation.

    Cycling Weekly
  • The Bicycle Association and the Association of Cycle Traders have launched an E-Bike Positive trust mark covering 33 brands and more than 600 stores, intended to identify road-legal e-bikes and the retailers who sell them.

    Cycling Industry News

The last of those is the one worth sitting with. A rider on a perfectly legal cargo bike lost it to a roadside test the force later accepted was wrong. Knowing what your bike is, and being able to show it, is not only about staying on the right side of the rules. It is also how you argue when someone else gets it wrong.

Common questions

Are electric bikes legal in the UK?
Yes, provided the bike meets the EAPC rules: a motor with a continuous rated power output of no more than 250 watts, assistance that stops at 15.5mph, working pedals, and a rider aged 14 or over. A bike meeting those rules is treated as a pedal cycle. You do not need a licence, and it does not need to be registered, taxed or insured.
Do I need a licence or insurance for an electric bike?
Not for an EAPC. gov.uk is explicit that you do not need a licence to ride one and that it does not need to be registered, taxed or insured. If the bike falls outside the EAPC rules then it is treated as a motorcycle or moped, and it must be registered, taxed and insured, with a valid driving licence and a motorcycle helmet meeting British safety standards.
How fast can a legal e-bike go?
The motor must not be able to propel the bike above 15.5mph. That is a limit on the assistance, not on you. You can pedal a legal e-bike faster than 15.5mph downhill or under your own effort, and doing so is fine. The bike is only outside the rules if the motor itself keeps driving it past that speed.
Is 250W the peak power or the continuous power?
Continuous rated power. This is the detail most often got wrong. A motor advertised as “250W nominal, 700W peak” is describing a continuous rating of 250W and a short burst capability, and can be compliant. A motor with a continuous rating above 250W is not, however it is marketed.
Are throttles legal on UK e-bikes?
Only in limited circumstances. gov.uk states that an electric bike can be propelled up to 15.5mph without pedalling only if it has been approved, and lists twist-and-go as an example of the kind of bike that needs that approval. In practice, if a used listing advertises a throttle, treat it as something to resolve before buying rather than a bonus feature.
Where can I ride an electric bike?
An EAPC can be ridden on cycle paths and anywhere else pedal bikes are allowed. You cannot ride it on pavements. A bike that does not meet the EAPC rules can only be used on the road, and cannot be ridden on cycle tracks or cycle lanes, which in practice means most non-compliant e-bikes have nowhere legal to go unless they are registered as motor vehicles.
What happens if my e-bike is not road legal?
It is classed as a motorcycle or moped. Using it on a public road means registering and taxing it, holding a valid driving licence, wearing a motorcycle helmet that meets British safety standards, and insuring it. Police forces are seizing non-compliant machines in significant numbers, and a seized bike can be destroyed rather than returned.
Can I still sell an e-bike that is not road legal?
Yes, but it should be described honestly as off-road or private-land use rather than presented as road legal. On Cyclesite, sellers can declare an e-bike’s road-legal status and it is shown on the listing, so buyers know what they are looking at before they travel. Describing a non-compliant bike as road legal is the thing that causes real harm to a buyer.
How do I check whether a used e-bike is legal before I buy it?
Ask for a photograph of the markings, which must show the continuous rated power output and the manufacturer plus either battery voltage or maximum assisted speed. Get the continuous power rating in writing. Ask whether it has a throttle and whether the motor was fitted at the factory or retro-fitted as a conversion kit. Treat “derestricted”, “unlocked” or “tuned” as a warning rather than a feature.
Do e-bike rules apply to electric mountain bikes and cargo bikes?
Yes. The EAPC rules are about power, assisted speed, pedals and rider age, not about the shape of the bike. A factory electric mountain bike or cargo bike from a mainstream brand is normally built to the 250W and 15.5mph limits for the UK and European markets, which is why most of them are compliant as sold.
