In our project bicycle is driven with a series of spur gears which will increase the speed of bicycle and also the bicycles becomes more efficient than a conventional sprocket driven bicycle. Spur gears are used in series to transmit power from the pedal to the rear wheel of the bicycle. This bicycle enables us to put less effort for pedaling. For a very low input effort, we can get maximum output. Distance covered by this gear driven bicycle for few minutes of pedaling will also be 3-4 times more than that of the ordinary sprocket driven bicycle.
