Recently, due to advancements in internal gear technology, a small number of modern how to drive a bike with gear pdf-driven bicycles have been introduced. The use of bevel gears allows the axis of the drive torque from the pedals to be turned through 90 degrees. The drive shaft then has another bevel gear near the rear wheel hub which meshes with a bevel gear on the hub where the rear sprocket would be on a conventional bike, and canceling out the first drive torque change of axis. The first shaft drives for cycles appear to have been invented independently in 1890 in the United States and Britain.
Fearnhead, of 354 Caledonian Road, North London developed one in 1890 and received a patent in October 1891. In the United States, Walter Stillman filed for a patent on a shaft-driven bicycle on Dec. 10, 1890 which was granted on July 21, 1891. The shaft drive was not well accepted in Britain, so in 1894 Fearnhead took it to the USA where Colonel Pope of the Columbia firm bought the exclusive American rights. 1896 book “Bicycles and Tricycles”, he writes “The Fearnhead Gear. In the USA, they had been made by the League Cycle Company as early as 1893. Soon after, the French company Metropole marketed their Acatane.
