Do you need a helmet for an e-bike in the UK?

What the law says

An electrically assisted pedal cycle, with a 250 W rated motor and assistance that cuts out at 15.5 mph, is not a motor vehicle in Great Britain. The gov.uk electric bike rules confirm that you do not need a licence, registration, tax or insurance to ride one. There is no law requiring cyclists, including EAPC riders, to wear a helmet.

Rule 59 of the Highway Code recommends wearing a cycle helmet that conforms to current regulations, is the correct size and is securely fastened. It is advice, not a legal requirement, but insurers and courts may take it into account after an accident.

Faster e-bikes are different

If a bike's motor is rated above 250 W, it assists above 15.5 mph or it has a throttle that drives it beyond walking pace, it is not an EAPC. It is treated as a moped or motorcycle, and the rider must wear a motorcycle helmet that meets the legal standard, as well as having a licence, registration, tax and insurance. Most such bikes sold online cannot be registered at all.

The same applies to a legal bike that has been derestricted. A cycle helmet does not satisfy the motorcycle helmet law. Our UK e-bike law explained and how fast does an e-bike go explain where the line falls.

Choosing a helmet for e-bike riding

Some helmets are sold as e-bike helmets with more coverage at the back and sides. They can suit commuters who ride near the 15.5 mph limit, though any helmet that meets a recognised cycle standard and fits well is suitable for an EAPC.

• A recognised cycle helmet safety standard, shown on the label inside.
• Correct size: measure your head circumference just above the eyebrows.
• A snug fit with no rocking, adjusted with the rear dial and straps.
• Good ventilation for warm days and longer rides.
• Integrated lights or reflective details for winter commuting.
• Optional: helmets tested to the Dutch NTA 8776 standard, designed for speed pedelecs, give extra coverage.

Fitting and caring for a helmet

Replace a helmet after any significant impact, even if no damage is visible, and follow the maker's guidance on replacement age. Store it away from heat and solvents.

1. 1

   Place the helmet level on your head, about two finger widths above your eyebrows.

2. 2

   Tighten the rear adjuster until it is snug but comfortable.

3. 3

   Adjust the side straps so they meet just below each ear.

4. 4

   Fasten the chin strap with room for about one finger underneath.

5. 5

   Shake your head: the helmet should not move independently.

Note:A helmet reduces some risks but does not prevent accidents. Ride at a speed that suits the conditions, use lights after dark and follow the Highway Code.

Other safety kit worth considering

Lights are required by law after dark: a white front light, a red rear light and a red rear reflector, plus pedal reflectors on bikes made after 1985. Many e-bikes have lights powered by the main battery. Bright or reflective clothing, gloves and glasses add comfort and visibility.

Security is another priority, as e-bikes are a common theft target. Our e-bike lock guide covers high-security locks, and our electric hybrid guide notes which models come with integrated lights.
