Title: BICYCLE WITH REAR WHEEL QUICK MOUNTING/DISMOUNTING MECHANISM
Abstract:
The present invention concerns a bicycle with a rear wheel quick mounting/dismounting mechanism. It essentially consists of transferring and attaching the sprocket cassette onto a seat stay of the rear part of the frame of a bicycle while keeping the freewheel mechanism housed in the rear wheel, housing a push/pull coupler on the end of the hollow shaft of the cassette, i.e. in the attachment nut that forms the fixed part of the coupler, coupling the freewheel mechanism and the cassette by shape fitting, and mechanically locking a pin forming the axis of rotation of the rear wheel with the coupler, then tightening the wheel with a cam mechanism attached to the pin.
