The present invention relates to a freewheel hub for a bicycle, comprising a freewheel device which optionally allows relative rotation between a hub sleeve and a driver or couples the hub sleeve and the driver in a torque-transmitting manner. The freewheel device has at least one first clutch ring and at least one second clutch ring, wherein the first clutch ring is coupled or coupleable to the hub sleeve in a torque-transmitting manner, and wherein the second clutch ring is coupleable or coupled to the driver in a torque-transmitting manner, and wherein the first and the second clutch ring are displaceable axially relative to the hub axle between an engaged position and a freewheel position. Provision is made here for at least one magnet arrangement accommodated in apertures in the first clutch ring to keep the clutch rings in the engaged position.
