The new national standard refers to the "Safety Technical specifications for electric bicycles". China is the world's largest electric bicycle production and sales country, in order to regulate the development of the industry, to ensure the safety of users' lives and property, the new national standard for the maximum speed of electric bicycles, vehicle weight, battery voltage and so on have made provisions. According to the requirements of the new national standard, the maximum design speed of the electric bicycle does not exceed 25 kilometers per hour and shall not be modified, the nominal voltage of the battery does not exceed 48V, and the motor power is adjusted from 240W to 400W compared with the old national standard of the electric bicycle. The vehicle mass (including battery) is adjusted from 40kg to 55kg, and the pedal riding function is mandatory, and the unique vehicle code (15 digits) is required to be permanently marked on the surface of the eye-catching part of the frame body that cannot be separated. Related content: After the implementation of the new national standard, there are three types of electric two-wheeled vehicles that are qualified, namely electric bicycles, electric mopeds and electric motorcycles. Of course, the premise is that the three types of cars meet their respective standards. Among them, electric bicycles need to have pedal riding function, maximum speed ≤25km/h, motor power ≤400w, battery voltage ≤48v, vehicle mass ≤55kg, belong to non-motor vehicles, (some provinces) allowed to carry a child under 12 years old. The maximum speed of electric mopeds is less than 50km/h, the battery specifications are not limited, the mass of the vehicle can be ≥55kg, which is a motor vehicle and is not allowed to carry people. The maximum speed of the electric motorcycle can be >50km/h, the battery specifications are not limited, the mass of the vehicle can be ≥55kg, which is a motor vehicle, allowing people to be carried, and can carry an adult.
