A DC motor with a one-way bearing applicable for driving various different electrical products includes a chassis, a motor shaft, a front output shaft and a rear output shaft. Front and rear one-way bearings are installed between the front end of the motor shaft and the inner end of the front output shaft and between the rear end of the motor shaft and the inner end of the rear output shaft and they are rotated in opposite directions. In a power output mode, the forward rotation of the motor shaft drives the front output shaft to rotate in a forward direction synchronously while the rear output shaft remains still, or the reverse rotation of the motor shaft drives the rear output shaft to rotate in a reverse direction synchronously while the front output shaft remains still.
