Rocker Arm Bike

What it does?

The Rocker Arm Bike is an efficient tandem bicycle that uses an alternate 3-Pin 1-Slider mechanism for its propulsion. As a result, the pedalling action is oscillatory instead of rotatory. This decreases the strain on the knees of the rider and also provides a mechanical advantage. The mechanism used is biomechanically efficient, wherein a given amount of energy input by the user results in a greater distance moved by the bicycle than would have been in the case of the conventional system. Here, the up and down motion of the lever is converted into rotatory motion of the wheels. It is sufficient for the user to apply force on the lever for a small angle rather than cranking the pedal in the existing circular way. The rider in the front uses the alternate mechanism and the rider at the back uses the conventional mechanism.
