The UK Office for Product Safety and Standards published guidance on November 11 explaining how existing product safety rules apply to kits that add electric assistance to pedal bicycles. The guidance introduces no new legal obligations.

Kits with an electric motor are covered even if they are sold without a battery or charger. The regulator reminds suppliers to provide the required product information, user instructions and markings. It also warns that incompatible batteries and chargers can increase the risk of fire.

The regulator says a converted bicycle that exceeds the 250-watt continuous rated power limit or the 15.5 mph limit for motor assistance falls under the rules for motor vehicles. The guidance covers these kits too.
