A drive apparatus for an electric bike includes a hollow housing body, an internal ring gear fixed to the housing body, and a main shaft. At least two motor units are mounted in the housing body. Each motor unit includes a support bracket and a number of motors mounted on the support bracket. Each motor drives the internal gear through a transmission mechanism to rotate the housing body about the main shaft. The motors share one controller. Peaks of the motor cogging torque can be staggered.
