The freewheel includes a driven member, a drive body, an inner freewheel ball bearing and an outer freewheel slide bearing. The driven member is fixed to the hub shell to rotate therewith, while the drive body is operatively coupled to the driven member by a one-way clutch mechanism. The inner freewheel ball bearing is disposed between the driven member and the drive body to rotatably support an inner end of the drive body on the driven member. The outer freewheel slide bearing is disposed between the driven member and the drive body to rotatably support an outer end of the drive body on the driven member.
