A power generation device for bicycle (1) comprises a piezoelectric power generation piece (3), a built-in power storage unit (4) and a power output bus (5). The piezoelectric power generation piece (3) and the power storage unit (4) are electrically connected with the power output bus (5) respectively, and the piezoelectric power generation piece (3) induces the up and down vibration generated by the saddle (21) or the frame of the bicycle (2) during riding to generate power by itself. And the power transmission between the power storage unit (4) and the piezoelectric power generation piece (3) is wireless or wired, and the power is stored in the power storage unit (4). Furthermore, the power generation device for bicycle (1) provides power usage for external via the power output bus (5). The piezoelectric power generation piece (3) of the power generation device for bicycle (1) generates power by the up and down vibration generated by the saddle (21) during riding, and the power is outputted to supply the peripheral products of the bicycle (2) via the power output bus (5). |
