|Road Legal Electric-Assist Bicycle|
The Tokyo Bureau of Citizens and Cultural Affairs purchased 5 different types of the electric power-assisted bikes, ranging from 30,000 to 60,000 yen, for testing. They sourced the bicycles from both highly recommended online retailers, and retailers who had received a high number of consumer complaints. Of those tested one was equipped with a throttle in a clear violation of the road traffic act and three of the five continued running after the rider had stopped pedalling. More alarmingly was that under Japanese regulations power assisted bicycle motors are designed to stop running once the rider reaches 24 kilometres per hour, but four out of the five bicycles tested continued to accelerate to even higher speeds.
Personally I've noticed an increase of throttle controlled electric bicycles in the Higashi Shinjuku and Shin Okubo districts near my office. Such a sharp increase that I thought maybe the law had been changed to make such bicycles legal. I've seen these bicycle in use within full view of police officers none of whom have so much as even warned the cyclist. If officials don't act soon their use will become commonplace and the police will lose the power to act as they have in so many other areas of Japanese cycling regulation.
Bicycle buyers are advised to check safety inspection marks including the Traffic Safety mark from the Japan Traffic Management Technology Association, Bicycle Association Approved mark from the Bicycle Association of Japan and the Safe Goods mark of the Consumer Product Safety Association.
