The invention provides a two-gear dual-motor hybrid power system, a hybrid power assembly and a vehicle. The two-gear dual-motor hybrid power system comprises an engine, a generator, a driving motor and a transmission. The transmission is provided with an input shaft and an output shaft which are arranged in parallel, the input shaft comprises a first input shaft body and a second input shaft body arranged on the first input shaft body in a sleeving mode, and power transmission units are arranged between the first input shaft body and the output shaft and between the second input shaft body and the output shaft. And the driving motor is arranged on the output shaft. A power output shaft of the engine, the generator and the input shaft are sequentially in transmission connection, and double clutches are arranged between the generator and the input shaft so as to transmit power from the engine to the first input shaft or the second input shaft. According to the two-gear dual-motor hybrid power system, the transmission efficiency in a pure electric driving mode can be improved, and the situation of power interruption existing in the gear shifting process of the system is improved.
