Motorcycles disguised as a "new type" of power-assisted bicycle are being sold to buyers who may not realise what they are, and police say this is creating safety risks on the streets. The Tokyo Metropolitan Police Department is warning people to check performance and specifications carefully before making a purchase. Some of these vehicles are not ordinary battery-assisted bicycles but fully electric motorcycles, sometimes referred to as mopeds.

A licence is not required for riding a power-assisted bicycle. That is not the case for these machines. Because they are effectively electric motorcycles, a licence is needed. Police also said some of the vehicles do not meet basic safety requirements. They were found without rear-view mirrors and licence plates, both of which are required for use on public roads in Japan.

An accident triggered an investigation into the nature of those vehicles. A pedal-equipped electric motorcycle sold by the company was involved in an accident with a taxi on a metropolitan road in Tokyo's Shinjuku Ward in June 2025. MPD officials said the man who was driving the motorcycle had no driver's license. He was quoted as telling investigators he believed he was riding a power-assisted bicycle. He received a summary indictment on charges of unlicensed driving and was fined 300,000 yen. Tokyo police said a bicycle look-alike can be a motorbike if, for example, it runs automatically without being pedaled or continues to be power-assisted past the legal maximum speed of 24 kph. They can also be configured with a smartphone app or through other means to exceed the legal assist ratio standard, or can be converted easily, including by installing a throttle, they said. Driving a vehicle that is not maintained properly and fails to meet safety standards could violate the Road Traffic Law.
