Abstract
A combination structure of bicycle frame and motor hub includes a bicycle frame, a motor hub, and an elongated axle. One can extend, from one side of the bicycle frame, the elongated axle through a through hole of the bicycle frame and the motor hub, and then with one hand, a tail end of the elongated axle can be fastened into an internal thread hole of the bicycle frame. This will facilitate assembly of the components of the motor hub and the bicycle frame. Besides, when screwing or unscrewing the elongated axle, since the elongated axle has passed through the through hole and the internal thread hole opposing each other at the bicycle frame, the motor hub will not fall accidentally, and convenience can be assured for maintenance staff during proceeding of maintenance work.
