A novel multi-speed wheel hub having a housing, an input member, including a sun gear, disposed in the housing, a planet carrier, including a plurality of planet gears, disposed about the sung ear. There is also a ring gear disposed about the planet gears. The multi-speed wheel hub includes a shifting system including a piston. A first shift ring is mechanically coupled to the piston by a plurality of first push rods and a second shift ring is mechanically coupled to the first shift ring by a plurality of second push rods. The piston activates the first and second shift rings, such that, when the first shift ring is engaged and the second shift ring is disengaged, the ring gear is locked to the housing so that a torque is transmitted from the sun gear through the planet carrier to the wheel. When the first shift ring is disengaged and the second shift ring is engaged, the ring gear is unlocked from the stationary member and the planet carrier is locked to the input member so that torque is transmitted from the sun gear to the wheel. A return spring may also be provided to return the shifting system to its initial position.
