The present invention relates to a two-gear transmission, and the purpose of the present invention is to provide a two-gear transmission which can be miniaturized due to the simple structure thereof and can rapidly transmit driving power of a power source to an output shaft without a loss of power. The present invention comprises: a power input unit having an input shaft to which driving power of a power source is transmitted and having a drive gear rotated integrally with the input shaft by a one-way bearing; a clutch unit connected to the input shaft of the power input unit and having a clutch gear connected on one side thereof; a rotation transmission unit rotated by selectively receiving torque from the clutch gear of the clutch unit or the drive gear of the power input unit; an output unit which receives driving power of the power source through the rotation transmission unit so as to rotate an output shaft; and a gear housing unit in which the power input unit, the clutch unit, the rotation transmission unit, and the output unit are installed, whereby two gear changes are performed according to whether the clutch unit is operated.
