China Standard for Electric Bicycles

The four main national standards for electric bicycles are: there must be pedals to enable human riding; the maximum design speed is not more than 20km/h; the mass of the vehicle is not more than 40kg; the motor output power is not more than 240w;

National Standard "General Technical Requirements for Electric Bicycles" (GB17761—1999)

Electric bicycle

Special bicycles that use storage batteries as auxiliary energy sources and have two wheels that can realize human riding, electric or electric assist functions.

skills requirement:

1. Maximum speed: should not exceed 20km/h; (Article 58 of the Traffic Law stipulates that the maximum speed of electric vehicles should not exceed 15 kilometers per hour)

2. Whole vehicle mass: not more than 40kg (including battery);

3. Pedal driving ability: Must have a good pedal riding function, and the pedaling 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 240W;

8. Braking performance: When riding electric at the highest speed (electrically assisted riding at a speed of 20km/h), the dry braking distance should not exceed 4m, and the wet braking distance should not exceed 15m.

According to the relevant regulations on the design maximum speed, empty vehicle quality, and external dimensions of the national general standards formulated in 1999, electric bicycles belong to the category of non-motorized vehicle management and should have the following five characteristics: they must have pedal driving function, and the battery is only used as Auxiliary energy; must have two wheels; the design speed is not more than 20 km/h; the weight of the vehicle is not more than 40 kg; the tire width (in-tire) is not more than 54 mm.

The model of electric bicycle is named TD (electric bicycle of special bicycle type). Although it has the appearance characteristics of ordinary bicycles (even the appearance characteristics of motorcycles), the main thing is that it is installed on the basis of ordinary bicycles with motor, controller, storage battery, turning handle and other operating parts and displays. The mechatronics of the instrument system is a personal vehicle.
