What are the technical requirements for electric bicycles?

Electric bicycles are special bicycles that use batteries as auxiliary energy sources and have two wheels that can realize human riding, electric or electric assist functions.
1. Maximum speed: should not exceed 25km/h; (Article 58 of the Traffic Law stipulates that the maximum speed of electric vehicles shall not exceed 15 kilometers per hour)
2. Whole vehicle mass: no more than 55kg (including battery);
3. Pedal driving ability: Must have a good pedal riding function, and the pedal driving distance of 30 minutes should be no less than 7km;
4. Continuation mileage: the continuation mileage after one charge should not be less than 25km;
5. Maximum riding noise: When the highest vehicle speed is used for electric uniform riding (electrically assisted riding at a speed of 15km/h～18km/h), the noise should not exceed 62dB(A); the power consumption of 100km should not exceed 1.2kW·h;
6. Electricity consumption per hundred kilometers: electric riding (electric-assisted riding with electric assist), the electric energy consumption of 100km should not be greater than 1.2KWH
7. Motor power: the rated continuous output power should not be greater than 400W;
8. Braking performance: When electric riding at the highest speed (electrically assisted riding at a speed of 20km/h), the dry braking distance should be no more than 4m, and the wet braking distance should be no more than 15m.
