The bicycle is only one of the many man-developed lever systems for land transport, but it is the sole remaining type that has a limited propulsive power. Millions of people around the world still rely on their trusty clunkers for cheap and efficient transportation. In fact, the global fleet approaches a billion, with the vast majority circulating in developing countries like Cuba and China where automobiles remain a luxury. Recreational riders continue to take to their wheels for exercise, adventure, and companionship. The Lever Driven Bicycle consists of the following parts: mounting plate, torsion spring and oscillating lever. The lever is pivoted at a point on the mounting plate which is fixed to the bicycle frame and a torsion spring is present in between the mounting plate and the lever. The end of the lever contains a gear sector which is in mesh with the free wheel. This changes the existing conventional driving mechanism by the oscillating motion of a lever into rotatory motion of the wheel. The downward motion of the lever is powered by the human leg and the return or the upward movement of the lever is achieved by the use of torsion spring. The main objectives of this project work is to reduce the effort which is required for cycling and provides a means of transportation to peoples with small disability to his or her legs (i.e. a person with a leg shorter than the other), reduced maintenance which is regularly required for a conventional bicycle (lubrication and tightening of the chain, freewheel and crank set), provides a way of transportation by applying effort only on a single lever and a new way for cycling to the cycling enthusiasts.
