The utility model discloses a speed reducing mechanism, a hub motor and an electric bicycle, the speed reducing mechanism comprises a first-stage speed reducing assembly, a second-stage speed reducing assembly, a third-stage speed reducing assembly, a one-way clutch and an inner gear ring, and the first-stage speed reducing assembly, the second-stage speed reducing assembly and the third-stage speed reducing assembly are sequentially installed in the inner gear ring. The first-stage planet gear is meshed with the first-stage sun gear and the inner gear ring at the same time; the second-stage planet gear is meshed with the second-stage sun gear and the inner gear ring at the same time, the third-stage planet gear is meshed with the third-stage sun gear and the inner gear ring at the same time, power is transmitted to the inner gear ring to be output through a third-stage planet gear transmission structure, and the forward torque amplification effect and the speed reduction effect are achieved. Power can be out
