The invention discloses a chain plate speed changer of a bicycle central shaft. The chain plate speed changer is arranged on the bicycle central shaft and used for replacing a common chain plate. The torque input by the central shaft is output to a chain after being processed by a gear change structure inside the chain plate speed changer, the input/output transmission ratio is determined by matching of different gears of the gear speed change structure; in the whole transmission process, the chain is always kept connected with an output fluted disk, so that separation or bouncing does not occur.
