The invention discloses a centrally-mounted motor and a power-assisted bicycle. The centrally-mounted motor comprises a shell; the motor module is arranged in the shell and used for generating torsion; the reduction gearbox module is connected with the motor module and is used for transmitting the torsion generated by the motor module; the controller module is connected with the reduction gearbox module and controls the motor module to start; wherein the motor module comprises a rotor, a motor stator and a motor shaft, the motor stator is formed by splicing a plurality of winding iron core single bodies, a cavity is formed in the middle of the motor stator, the rotor is embedded in the cavity of the motor stator, and the rotor is arranged on the motor shaft in a sleeving mode. The centrally-mounted motor provided by the invention adopts a modular design, and each module can be independently produced and manufactured, so that the whole motor is simple in structure and convenient to disassemble and assemble, and meanwhile, the spliced motor stator is adopted, so that winding processing is facilitated, and the purposes of reducing the production cost and improving the production efficiency and the maintenance efficiency are achieved.
