  • a device that uses this idea of regeneration of the energy developed in braking, in the compression of the ambient air and its storage once compressed in a tank, so that when it is necessary to overcome a greater resistance to the advance of the bicycle or an increase in speed, or both at the same time, the stored compressed air is expanded, in the compressor itself so that it now functions as a pneumatic motor, thus helping to increase the torque produced by the cyclist's pedaling.
