ABSTRACT:
A doubly convertible bicycle wheel hub assembly has an axle housing containing sealed dustproof precision bearings with the axle journalled therein, the ends of the axle housing having annular retainers thereon either one of which can be replaced by a specialized retainer-freewheel mount element which, when the freewheel mechanism is mounted thereto, converts the hub assembly for use on the rear wheel of a bicycle. The freewheel assembly itself utilizes an annular sprocket element for the bicycle chain drive which is very simply removable and replaceable by removing a threaded retainer ring such that the chain drive ratio can be altered without replacing the entire freewheel mechanism.
