The invention provides a two-gear transmission for a pure electric vehicle and the pure electric vehicle. The two-gear transmission comprises an input shaft, a mechanical transmission mechanism, a differential assembly, a brake and a clutch, and the input shaft is connected with a driving motor of the pure electric vehicle; the mechanical transmission mechanism is assembled on the input shaft; the differential assembly is connected with the mechanical transmission mechanism; the brake is connected to the transmission shell and further connected with the mechanical transmission mechanism and has a free state and a locking state. The clutch is connected between the input shaft and the mechanical transmission mechanism and has a combined state and a disengaged state; when the pure electric vehicle runs at a first gear, the brake is in a locking state and the clutch is in a disengaged state, when the pure electric vehicle runs at a second gear, the brake is in a free state and the clutch is in a combined state, and when the pure electric vehicle runs at a reverse gear, the brake is in a locking state and the clutch is in a disengaged state. Therefore, the power performance of the whole vehicle can be greatly improved under the condition of increasing a small amount of cost and weight.
