Chainless Bicycle

Abstract

This project is developed for the users to rotate the rear wheel of a two-wheeler using propeller shaft. Power transmission through chain drive is the oldest and widest used method in case of bicycle. In this paper we implemented the chainless transmission to the bicycle to overcome the various disadvantages of chain drive. Shaft drives were introduced over a century ago, but were mostly supplanted by chain-driven bicycles due to the gear ranges possible with sprockets and derailleur.

Recently, due to advancements in internal gear technology, a small number of modern shaft-driven bicycles have been introduced.  Usually in two wheelers, chain and sprocket method is used to drive the back wheel. The shaft drive only needs periodic lubrication using a grease gun to keep the gears running quiet and smooth.
