<p>Disclosed are an apparatus for replenishing energy in a flywheel battery when a bicycle is going downhill and a method of use. The bicycle is provided with a manual engaging and disengaging device and a motive power assembly (2), wherein the manual engaging and disengaging device controls whether to replenish energy in a flywheel battery (3) according to the state of travel of the bicycle; and the motive power assembly receives the driving force of a bicycle rear wheel (72) and replenishes energy in the flywheel battery. The benefit is that in the case of no power source, the bicycle can be used to replenish kinetic energy in the flywheel battery. Manually controlling the time for replenishment of energy in the flywheel battery lightens the manpower load. Thus, when the bicycle is going downhill, the apparatus couples with the bicycle to provide kinetic energy to the flywheel (31); and when the bicycle is going uphill or travelling along a flat, the apparatus separates from the bicycle to lighten the manpower load. Using the principle of centrifugal force means that after stopping driving, a drive mechanism can automatically separate from the flywheel to prevent unnecessary wastage of energy from the flywheel.</p> |
