A crank-lever bicycle is a bicycle that uses a drive crank instead of a chain to transmit power from the effort arm to the rear wheel.
In this chainless bicycle the origin of pedal has been changed, usually it is near chain wheel, but in this chain less bicycle the pedal
is placed at the back frame, it is fabricated in such a manner that it is above the rear wheel center. The pedal which is an effort arm
is attached with a bush which is then bolted with the frame with a bearing so it can transmit the motion smoothly, and locked by a
circlip so that it is prevented from moving away from the centre
