An auxiliary power device adapted for use with a bicycle includes a drive unit (20), first and second one-way transmissions (32, 60) that are adapted to be mounted in a bike frame (10) of the bicycle, a crankshaft (41) and a transmission sprocket (50). The first one-way transmission (32) is connected between the drive unit (20) and the transmission sprocket (50) . The second one-way transmission (60) is mounted between the crankshaft (41) and the transmission sprocket (50). When rotation of the transmission sprocket (50) is driven by the drive unit (20) via the first one-way transmission (32), the second one-way transmission (60) is idling. When rotation of the transmission sprocket (50) is driven by the crankshaft (41) via the second one-way transmission (60), the first one-way transmission is idling (32).
