Abstract
A bicycle is equipped with an auxiliary power system to provide extra power for driving the bicycle forward. The auxiliary power system includes a base fixed to a frame of the bicycle, a power storage device connected to the base, and a ratchet device connecting the power storage device and a main transmission system of the bicycle. When pedals of the bicycle are turned in a forward direction, it may drive the bicycle forward but not the power storage device through the ratchet device. When the pedals are turned in a rearward direction, it may drive the power storage device through the ratchet device to store extra power in the power storage device. A rider may release the power stored in the power storage device to drive the bicycle forward through the ratchet device and the main transmission system.
