The invention discloses a double-drive bicycle with a variable front drive structure, and belongs to the technical field of bicycles. The bicycle mainly comprises a frame (14), a front wheel, a rear wheel, a saddle and pedals (15). The bicycle is characterized in that the upper part of the front end of the frame (14) is connected with a cylinder (1) through a cross rod (13); a T-shaped cylinder (5) is arranged at the front end of the frame (14); a primary transmission device (4) is arranged between the left side of the cylinder (1) and the T-shaped cylinder (5); and a secondary transmission device (8) is arranged between the right side of the T-shaped cylinder (5) and the front wheel hub. The front wheel drive and the rear wheel drive can be carried out at the same time and can also be carried out independently, lactic acid released by anaerobic movement in the riding process is avoided, and the drive capacity and practicability of the bicycle are greatly improved.
