[0032] Working principle: When in use, first place the assisted bicycle on the placing base 1, support the frame of the assisted bicycle through the support plates 21 and the contact pads 22 to make it stand upright on the placing base 1. At the same time, the front wheel of the assisted bicycle is placed on the U-shaped placing frame 10. Then start the drive motor 16.

The bidirectional threaded rod 7 drives the other three bidirectional threaded rods 7 to rotate synchronously through the combination of the double-row synchronous pulley 11 and the first synchronous belt 12 and the single-row synchronous pulley 13 and the second synchronous belt 14.

Subsequently, the tester compares according to the rotation angle and the driving logic of the steering assist structure to realize its detection function.
