The invention discloses an electric bicycle drive axle. An assistance ring, a spring and a resistance ring are also mounted on a first-level gear shaft; the assistance ring, the spring and the resistance ring are connected from left to right in sequence; limit sheets are respectively mounted on the left side and the right side of each of the assistance ring and the resistance ring; and the assistance ring and the resistance ring are in key connection with the first-level gear shaft. The electric bicycle drive axle has the beneficial effects that resistance is provided during braking, so that the braking efficiency is improved; meanwhile, the mechanical energy of an electric bicycle is changed into elastic potential energy for storage, then the elastic potential energy is released again during acceleration so as to provide power for the electric bicycle; and not only is energy saved, but also braking and accelerating efficiencies are improved.
