A two-stage speed-change output device includes a main axle, on which a motor assembly and first and second speed-change assemblies are mounted. The first and second speed-change assemblies are mounted inside an output shell by first and second one-way clutching elements, both operating in a forward direction. The motor assembly is operable to rotate backward to drive the first one-way clutching element to drive the output shell to rotate in the forward direction, while the second one-way clutching element idles. The motor assembly is also operable to rotate forward to drive the second one-way clutching element to drive the output shell to rotate in the forward direction, while the first one-way clutching element idles. The device realizes speed change for two stages to drive the output shell in the same direction with forward and backward rotations of the motor assembly.
