My idea is about more energy efficient bicycle. From the 18th century, we are following the same structure and principles in bicycle. I am proposing a simple change in bicycle; it runs almost 40 percent more efficiently than old models.
It is useful because it is a very simple method. It can be installed on any bicycle available in the market. This modification can reduce effort by 40 percent (less energy) for cycling. It uses a new principle. This new mechanism allows for more torque, so it will support a new gearbox system.
