The invention discloses an electric motorcycle power assembly which comprises a shell, a battery, a motor and a controller, the battery, the motor and the controller are all arranged in the shell, and the battery is connected with the motor through the controller; the power assembly further comprises a water cooling system, the water cooling system comprises a heat conduction plate, a radiator, cooling liquid and a water pump, a water tank is formed in the inner wall of the shell, the heat conduction plate is installed on the inner wall of the shell and covers the water tank, so that a first flow channel and a second flow channel with two open ends are formed in the inner wall of the shell, and the motor comprises a machine shell and a rotor rotationally connected in the machine shell. A third flow channel is arranged in the wall of the machine shell. A cooling loop is formed among the first flow channel, the second flow channel, the third flow channel, the radiator and the water pump, and cooling liquid is arranged in the cooling loop. According to the electric motorcycle power assembly, the integration degree is higher, the safety of a battery is improved, a water cooling system is lighter, and a controller and a motor are convenient to maintain or replace.
