FREEWHEELING HUB FOR A BICYCLE

The present invention relates to a freewheel hub for a bicycle comprising: - a hub axle, - a hub shell that is rotatably mounted on the hub axle via a bearing assembly, - a driver that is rotatably mounted on the hub axle and can be connected to at least one sprocket assembly, - a freewheel device that is arranged between the hub shell and the driver and selectively permits relative rotation between the hub shell and the driver or couples the hub shell and the driver in a torque-transmitting manner, wherein the freewheel device comprises at least a first clutch ring and at least a second clutch ring, wherein the first clutch ring is coupled or can be coupled to the hub shell in a torque-transmitting manner, and wherein the second clutch ring can be coupled or is coupled to the driver in a torque-transmitting manner, wherein the two clutch rings have mutually facing teeth, and wherein the first and second clutch rings are axially displaceable relative to the hub axle between an engaged position in which the teeth mesh with each other in a torque-transmitting manner and a freewheel position in which the teeth do not mesh with each other. It is provided that at least one magnetic assembly received in openings in the first clutch ring holds the clutch rings in the engaged position, wherein the openings for receiving the magnetic assembly in the first clutch ring are arranged and designed such that upon relative rotation between the first and second clutch rings the clutch rings can be transferred in the axial direction from the engaged position into the freewheel position and back.
