[0002] Currently, existing electric motorcycles typically have a mounting bracket welded to the bottom of the frame to secure the battery assembly. For example, Chinese utility model patent CN201922269317.6, entitled "A High-Performance Electric Motorcycle Chassis Structure," discloses a high-performance electric motorcycle chassis structure, including a frame. The frame includes a frame body, a front fork mechanism, and a rear fork mechanism. The frame body is a dual-tube structure, including a middle frame, a head tube, a lower frame, a rear frame, and a mounting bracket. A shock-absorbing spring is provided between the rear fork mechanism and the frame body, tilted forward and upward. The two ends of the shock-absorbing spring are hinged to the rear fork mechanism and the frame body, respectively.
