Common structure of electric bicycle

Most electric bicycles use hub motors to directly drive the front or rear wheels to rotate. These in-wheel motors are matched with wheels of different wheel diameters according to different output speeds to drive the whole vehicle at a speed of up to 20km/h. Although the shape of these electric vehicles and the installation position of the battery are not the same, there are commonalities in their driving and control principles. This type of electric bicycle is the mainstream of electric vehicle products.
