The invention discloses a differential driver of a double-drive bicycle. The differential driver comprises a driving shaft connected to the interior of a driving shaft shell in a rotary mode. The two ends of the driving shaft extend out of the driving shaft shell and are fixed to pedals respectively. A shaft sleeve is fixed to the portion, located in the driving shaft shell, of the driving shaft. A plurality of branch shafts perpendicular to the axis are arranged on the circumferential face of the shaft sleeve. Planetary gears are connected to the branch shafts in a rotary mode. Output shaft sleeves are coaxially arranged at the portions, located on the two sides of the shaft sleeve, of the driving shaft in a sleeving mode. A gear matched with each planetary gear is arranged at the end, facing the shaft sleeve, of the corresponding output shaft sleeve, and the other end of each output shaft sleeve extends out of the driving shaft shell to be fixed to a bicycle driving chain wheel. The bicycle driving chain wheels are in transmission connection with a front wheel and a back wheel of the bicycle respectively. By means of the structure, the differential driver of the double-drive bicycle has the advantages that the front wheel and the back wheel of the bicycle can provide driving force, and the riding capacity of the bicycle can be improved.
