A two-stage speed-change output device includes a main axle (100), on which a motor assembly (10) and first and second speed-change assemblies (20, 30) are mounted. The first and second speed-change assemblies (20, 30) are mounted inside an output shell (40) by first and second one-way clutching elements (29, 34), both operating in a forward direction. The motor assembly (10) is operable to rotate backward to drive the first one-way clutching element (29) to drive the output shell (40) to rotate in the forward direction, while the second one-way clutching element (34) idles. The motor assembly (10) is also operable to rotate forward to drive the second one-way clutching element (34) to drive the output shell (40) to rotate in the forward direction, while the first one-way clutching element (29) idles. The device realizes speed change for two stages to drive the output shell (40) in the same direction with forward and backward rotations of the motor assembly (10).
