Abstract

An electric auxiliary wheel is mounted on the rear wheel of a bicycle. The electric auxiliary wheel comprises an assembly structure and an electric auxiliary wheel frame. The electric auxiliary wheel frame is connected to the bicycle rear wheel through the assembly structure. The assembly structure comprises a positioning plate that can be detachably mounted on the axle of the bicycle rear wheel, allowing users to mount the electric auxiliary wheel on any bicycle. In addition, the assembly structure features two telescopic components that are mounted on the positioning plate and connected to a T-shaped suspension mounting seat. The T-shaped suspension mounting seat is connected to the electric auxiliary wheel frame by two suspension relief plates, thereby assembling the frame with the assembly structure. The present disclosure evenly distributes the vibrations generated by an auxiliary wheel and an electric hub, thereby enhancing the stability of the structure.
