Abstract

The present invention relates to a motor drive apparatus comprising a housing, a bottom housing and a crank rotatably mounted in an open end of the housing, and a mounting cavity formed between the housing and the bottom housing, the first end of the crank being rotatably mounted to the housing One end of the bottom case includes a middle shaft extending along the axial direction of the bottom case and passing through the bottom case, and an eccentric motor, a cycloidal gear reduction mechanism, a first clutch mechanism and a second clutch mechanism disposed in the installation cavity; The first end of the central shaft extends into the mounting cavity and is mounted into the first end of the crank; the two ends of the eccentric motor are rotatably mounted to the outer casing and the bottom casing respectively; the cycloid gear reduction mechanism is sleeved to the outer circumference of the eccentric motor; A clutch mechanism is rotatably mounted to the outer casing and can drive the outer casing to rotate; the second clutch mechanism is sleeved to the outer periphery of the first end of the central shaft and mounted to the outer casing. The invention can be installed at the axial position of an existing bicycle frame.
