A bicycle without chain is a bicycle that transmits energy to the driven wheel through a mechanism other than a metal chain. A bicycle powered by the axle is a bicycle that uses a transmission shaft instead of a chain to transmit energy from the pedals to the wheel. Axle transmissions were introduced more than a century ago, but were mostly supplanted by chain bikes due to the possible gear ranges with pinions and derailleur. Recently, due to advances in internal gear technology, a small number of modern bikes driven by the axle have been introduced.
Axle driven bikes have a large conical gear where a conventional bike would have its chain ring. This meshes with another bevel gear mounted on the drive shaft. The use of bevel gears allows the pedal drive shaft to be rotated 90 degrees. The drive shaft then has another conical gear close to the hub of the rear wheel engaging a conical gear in the hub where the rear sprocket would be on a conventional bicycle, and overriding the first drive torque change of the shaft.
