Disclosed in the present application are a wheel hub motor and a power-assisted electric bicycle. The wheel hub motor comprises a main shaft (100), a motor casing (200), a motor (300), a multi-stage planetary speed reduction mechanism (400) and a clutch (500). The motor casing (200) is rotatably mounted on the main shaft (100). The motor (300) is arranged in the motor casing (200). The multi-stage planetary speed reduction mechanism (400) is provided with an input end and an output end, and the input end is fixedly connected to a rotor (310). The clutch (500) comprises a driving portion (510) and a driven portion (520), the driving portion (510) is fixedly connected to the output end, and the driven portion (520) is fixedly connected to the motor casing (200), wherein the output end rotates in the first direction relative to the motor casing (200), so that the driving portion (510) is engaged with the driven portion (520), and the output end rotates in the second direction relative to the motor casing (200),
