The invention discloses a motor and an electric bicycle, the motor comprises a shell, a stator, a rotor and a speed reducing mechanism, the stator is fixed in the shell, the rotor is rotatably installed in the stator, the center position of the rotor is provided with a center hole penetrating in the axial direction, the speed reducing mechanism is connected with the rotor and used for outputting power, the speed reducing mechanism is at least partially located in the center hole. According to the motor, at least part of the speed reducing mechanism is arranged in the center hole of the rotor in the axial direction of the rotor, so that the overall axial size of the motor can be reduced, the space occupied by the motor is reduced, the motor structure is more compact, light weight and miniaturization of the motor are facilitated, and the motor can adapt to more application scenes.

    本发明公开了电机及电动自行车,其中电机包括外壳、定子、转子和减速机构,定子固定于外壳内,转子可转动安装于定子内,转子的中心位置具有沿轴向贯穿的中心孔,减速机构与转子连接,用于输出动力,其中,沿转子的轴向,减速机构至少部分位于中心孔内。该电机通过在转子的轴向上,将至少部分减速机构设于转子的中心孔内,从而能够减少电机整体的轴向尺寸,减少电机占用的空间,从而使得电机结构更为紧凑,有利于实现电机的轻量化和小型化,使得电机能够适应更多的应用场景。
