When the speed sensor 34 detects that the speed of the electric bicycle is slower than the limited value without rotating the 43 and the second unidirectional gear 23, the storage battery 15 is energized again, and if it is repeated, the energy saving effect is achieved and the brake. When the U-shaped iron seal 10 is pressed, the right side of the U-shaped iron seal 10 is pushed, the generator 50 is connected to the storage battery 15, and the first rotating shaft 44 rotates the second umbrella gear 45 to rotate the first umbrella gear 46. Then, the second drive shaft 48 rotates to rotate the generator 50, the generator 50 generates power, the storage battery 15 is charged by the rectifier 12, and resistance is generated in the process of generating power, so that the electric bicycle is stopped.

The above is merely a specific embodiment of the present invention, and the scope of protection of the present invention is not limited to this.
