POLICE are reminding riders to check that their electric bikes comply with UK law amid growing concerns about illegal and modified e-bikes being used on public roads, cycle lanes and shared spaces.

To be classed as a legal Electrically Assisted Pedal Cycle (EAPC), an e-bike must have pedals that can be used to propel it, a motor with a maximum continuous rated power of 250 watts, and must not provide assistance once the bike reaches 15.5mph (25km/h).

It must also meet UK EAPC regulations.

Police say an e-bike may be illegal if it can be powered without pedalling (outside of permitted walk-assist modes), has been modified to exceed speed limits, or uses a motor above the legal power limit.

Riders may also be breaking the law if they use non-compliant bikes on public roads without the required registration, insurance, or licence.

Illegal e-bikes can be seized by police and may result in fines, penalties, or prosecution linked to dangerous riding and road traffic offences.

Officers are urging riders to buy from reputable retailers, avoid modifications, and ensure their e-bike meets UK regulations before use.
