This project is the design of a chainless bicycle. The bicycle designed in the project employs a drive shaft instead of chain to transmit power from the pedals to the wheel. Shaft driven bicycles are introduced using the advanced gear technology. In this project the Engine is connected to the front part of the vehicle and the shaft of the engine is connected to a long rod. The other side of the rod is connected with set of bevel gears. The bevel gears are used to rotate the shaft to 90 degrees. The back wheel of the bicycle is also connected with the bevel gear which rotates the back wheel in perpendicular to the gear shaft. This whole process is responsible for the forward movement of bicycle. The forward or the reverse movement of the bicycle depends on the motion of the engine. There is no requirement of chain or sprocket method. This project is useful as it reduces human efforts and power to drive a bicycle.
