The invention discloses an automatic three-gear variable-speed motor structure for a bicycle and a variable-speed method thereof, relates to the technical field of bicycle gear shifting, and aims to solve the problem that the manufacturing cost is increased due to the fact that the overall structure of an existing bicycle variable-speed structure cannot support three-gear variable speed in a small space. According to the technical scheme, the three-gear speed change mechanism is characterized by comprising a center shaft, a three-gear speed change structure and a motor shell assembly used for outputting power, and the three-gear speed change structure internally comprises a centrifugal clutch gear shifting mechanism used for converting output modes and a composite planetary gear ring used for being matched with the centrifugal clutch gear shifting mechanism to achieve partial gear shifting; a first-stage transmission mechanism, a second-stage transmission mechanism and a third-stage transmission mechanism which are used for achieving overall multi-stage speed change are further arranged in the three-gear speed change structure, and the centrifugal clutch gear shifting mechanism is used for switching the first-stage transmission mechanism, the second-stage transmission mechanism and the third-stage transmission mechanism to conduct transmission in different modes. The effects of simplifying the structure, compressing the structure space, improving the transmission efficiency and reducing the cost are achieved.
