The invention discloses a hub motor and an electric bicycle, the hub motor comprises a main shaft, a casing, a motor, a multi-stage planetary reducing mechanism and a clutch, the casing is rotatably mounted on the main shaft, the motor is arranged in the casing, the multi-stage planetary reducing mechanism is provided with an input end and an output end, the input end is fixedly connected with a rotor, and the clutch comprises a driving part and a driven part. The driving part is fixedly connected with the output end, the driven part is fixedly connected with the machine shell, the output end rotates in the first direction relative to the machine shell so that the driving part can be connected with the driven part, and the output end rotates in the second direction relative to the machine shell so that the driving part can be separated from the driven part. According to the wheel hub motor, speed reduction is carried out through the multi-stage planetary speed reduction mechanism, so that a large speed reduct
