1. Power and speed are different. In terms of power, the power of electric motorcycles is greater than that of electric bicycles; In terms of speed, the speed of electric motorcycles is faster than that of electric bicycles.

2. The weight and volume are different. In terms of weight, electric motorcycles are generally heavier than electric bicycles; In terms of volume, the volume of electric scooters is larger than that of electric bicycles.

3. The motor power is different. The motor power of electric motorcycles is above 500W, while the motor power of electric bicycles is below 500W, so the motor power of electric bicycles is smaller than that of electric motorcycles; But electric bicycles are relatively lightweight, so they are more fuel-efficient and have stronger range.
