When we want to ride bicycle, it requires a lot of energy for us to move the pedal in order to move the bicycle. This system can store energy while we stop the bicycle, help us to convert the stored energy into kinetic energy, and then help us to move the bicycle. Bicycle riding will be much easier with this system.
