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.
