Brief: Electric-assisted bicycles, as an excellent alternative to traditional bicycles, are becoming more and more popular in Japan and many other countries/ regions around the world. In order to regulate product quality and ensure road traffic safety, the Japanese government stipulates that electric-assisted bicycles shall be supervised by the National Public Safety Commission, and go through the type approval certification in accordance with Article 39-3 of the Japanese Road Traffic Law Implementation Rules. Companies/factories that produce, assemble, or sell electric-assisted bicycles should be noted that their products shall be certificated before entering into the Japanese market.
SPECIAL TECHNICAL REQUIREMENTS FOR ELECTRIC-ASSISTED BICYCLE
In addition to meeting the technical requirements as the traditional bicycles, such as frame durability, wheel durability, handlebar fatigue performance and pedal wear resistance, electric-assisted bicycles also have a special requirements of power ratio between electric power and human power (hereinafter referred to as Power Ratio) requirements. When the speed of the electric-assisted bicycles does not exceed 24km/h, electric power can be used. The Power Ratio requirements are as follows: When the speed is less than 10km/h, the ratio=2; when the speed is 10km/h or more and below 24km/h, the ratio=2-( the speed -10)/7. When the speed of the electric bicycle is greater than 24km/h, the use of electric assist must be prohibited.
