The present invention provides a mid-motor drive system for an electric bicycle, which includes a left shell (1), a right shell (2), a motor assembly (3), a gear reduction apparatus (4), a torque sensor (5), a central shaft (7), a controller (8), and a crankset (9), and further includes a planetary gear increase apparatus (6). The gear reduction apparatus is connected to the motor assembly, the planetary gear increase apparatus, and the crankset, the planetary gear increase apparatus is connected to the torque sensor and the central shaft, the torque sensor is connected to the controller, and the controller is connected to the motor assembly. The present invention can allocate an assist ratio of a motor more accurately, so as to achieve the objectives of comfortable riding, energy conservation, and environmental friendliness; meanwhile, a planetary gear increase apparatus is built inside a motor drive system, thereby making a mid-motor drive system more stable and extending a service life.
