Geared Front Driver Circa 1893
The Geared Front Driver was one of the last bicycles of the high wheel type. The G.F.D. usually incorporates a Crypto or epicyclic gear to drive the front hub. This allowed a smaller diameter wheel to be geared up. This machine may be a "patent model" or prototype. It uses a 36" drive wheel geared up by a unique drive mechanism. Its 2 to 1 ratio provides a 72" gear. It is believed to be one of a kind.
