DESIGN AND FABRICATION OF COMPRESSED AIR BIKE

Abstract

For years, the transportation industries have been aiming at newer concepts of vehicles that has less dependency on fossil fuels for its fuel; zero emissions at a considerably lower cost. Bikes have known to been the eco-friendliest mode of transportation at a relatively lower cost, independent from using fuel to facilitate its movement. The mechanism too is much less I 0 complicated than other vehicles, but a lot of mechanical effort is required to create motion. This can be effectively reduced to a minimum effort by employing a gearing mechanism which is actuated by a piston-cylinder controlled by compressed air cylinder. The use of fresh air to drive a vehicle can be considered as the eco-friendliest fuel, as it is available in abundance and the air which is released by the vehicle is in the same form as it is being taken in and there is no harm to the environment.
