Hub for at least partially muscle operated vehicles

The hub (1) has a toothed disk freewheel (5) with two engagement components (6, 7) i.e. toothed disks, which co-act with one another and are provided with axial toothings. The toothings are biased to an engaging position via a biasing device, which is formed as a compression spring and a pulling force device that pulls the toothings toward one another. The components are provided with magnetic devices that are connected with the toothings such that a south pole of the magnetic device of one of the toothings is arranged adjacent to a north pole of the magnetic device of the other toothing.
