[0038] The middle part of the driving wheel 1 is provided with a handlebar connection through hole 11. The driven wheel 2 is located behind the driving wheel 1 and meshed with the driving wheel 1. The rotating shaft 3 is connected to the driven wheel 2. The rotation of the driving wheel 1 drives the driven wheel 2 to rotate, thereby driving the rotating shaft 3 to rotate. The base 4 is connected to the rotating shaft 3 through the bearing 6. The angle sensor 5 is arranged on the base 4 and sleeved on the outside of the rotating shaft 3. The angle sensor 5 is used to detect the rotation angle of the driven wheel. In specific implementation, the middle hole of the angle sensor 5 is usually a D-shaped hole, and the D-shaped hole in the middle of the angle sensor 5 can be rotated by a certain angle to realize the angle monitoring function. The connection part between the rotating shaft 3 and the angle sensor 5 also forms a D-shaped shaft structure. The rotating shaft 3 is inserted into the D-shaped hole of the angle sensor 5, thereby driving the D-shaped hole of the angle sensor 5 to rotate, thereby realizing the function of monitoring the angle.
