Four national standards for electric bicycle is the most main

Four national standards for electric bicycle is the most main: there must be a foot can realize human cycling; The highest design speed is not more than 20 km/h; The mass is not more than 40 kg; Motor output power is not more than 240 w. The national standard "electric bicycle general technical conditions" (GB17761-1999)Electric bicycle(electricbicycle) with battery as the auxiliary energy, has two wheels, can realize Cargo bike riding, electric or electric power-assist function of special bike.
Technical requirements:
1. The top speed: should be not more than 20 km/h; (" JiaoFa "article 58, electric cars at a top speed of not more than 15 km)
2. The vehicle quality: no more than 40 kg (including battery);
3. The foot driving ability: must have a good function of pedal cycling, 30 min pedal distance should be not less than 7 km;
4. Line continuation mileage: after a charge line continuation of mileage should not be less than 25 km;
5. The maximum cycling noise: when the top speed for electric bike at A constant speed (electric power-assist to 15 km/h ~ 18 km/h speed electric power-assist ride) the noise Three wheel bikes be no greater than 62 db (A); 100 km of power consumption should be not more than 1.2 kW · h;
6. Hundreds of kilometers of power consumption: by electric bike (electric power electric power-assist cycling), power consumption should be no greater than 100 km1.2 KWH
7. The motor power: rated continuous output power should be no greater than 240 w.
8. Braking performance: at the highest speed electric bike in the (electric power-assist at speed of 20 km/h electric power-assist cycling), dry state braking distance should be not more than 4 m, wet braking distance should be not more than 15 m.
