An electrical drive includes a housing mounted on a crank axle for partially receiving the axle. A driven ratchet base is rotatably mounted on a first end portion of the crank axle and includes a first end portion fixedly engaged with a chain wheel and a second end portion formed with a driven bevel gear. A drive bevel gear meshes with the driven bevel gear for rotating the driven ratchet base. A drive ratchet base is rotatably mounted on a mediate portion of the crank axle and includes a first end portion engaged with the second end portion of the driven ratchet base for rotating the driven ratchet base along one direction only, and a second end portion formed with a first engaging bevel gear. A ring element is fixedly mounted on the mediate portion of the crank axle to rotate therewith, and two pivot axles each extend from an outer wall of the ring element and each have a second engaging bevel gear rotatably mounted and meshing with the first engaging bevel gear. A retaining bevel gear meshes with each of the two second engaging bevel gears and is fixedly retained by an inner wall of the housing.
