The invention discloses a speed changing system of an intelligent bicycle. The speed changing system comprises a controller and a gear-shift chain prodding device connected with the controller. Pressure measuring devices are mounted on pedals of the bicycle. The pressure measuring devices detect the pedaling pressure of a rider and transmit pedaling pressure signals to the controller. The controller calculates out pedaling frequency according to the changing cycle of the pedaling pressure, and the current optimal riding gear is calculated out according to the pedaling frequency and the pedaling pressure. A chain is prodded by the gear-shift chain prodding device, and shifting of gears is realized. The speed changing system disclosed by the invention is high in gear shifting intelligent degree, accurate in gear shifting, and good in riding comfort.
