The invention discloses a motor electric control two-gear new energy speed reducer integrated assembly. An input shaft is directly matched with a driving motor through a spline to conduct torque transmission, and a first-stage driving gear and a second-stage driving gear are installed on the input shaft; a first-stage driven gear, a synchronizer, a second-stage driven gear and a main reduction driving gear are installed on an intermediate shaft, the first-stage driven gear and the first-stage driving gear are engaged to form a large-torque low-speed high-speed ratio, the synchronizer is located between the first-stage driven gear and the second-stage driven gear, and the second-stage driven gear is engaged with the second-stage driving gear to form a small-torque high-speed low-speed ratio. A shifting fork is connected with an integrated gear shifting motor and matched with the synchronizer. A main reduction bull gear is engaged with the main reduction driving gear and is connected with a differential mechani
