The invention provides a middle motor and a moped, and relates to the technical field of mopeds. The middle motor comprises a driving device with a driving shaft, a transmission device comprising a fixed gear ring, a movable gear ring, a sun gear and a plurality of planet gears, and an output device comprising an output shaft, a first rotating part, a second rotating part, a first clutch and a second clutch. The sun gear is connected with the driving shaft, the multiple planet gears are arranged in the circumferential direction of the sun gear at intervals, each planet gear is meshed with the sun gear, the fixed gear ring and the movable gear ring, the output shaft is connected with the movable gear ring, and the first rotating part rotationally penetrates through the driving shaft, the sun gear, the fixed gear ring, the movable gear ring, the output shaft and the second rotating part and is coaxially arranged. The first clutch is arranged between the first rotating piece and the output shaft, and the second clutch is arranged between the second rotating piece and the output shaft. According to the middle motor provided by the invention, a coaxial design and a planetary speed reduction structure are adopted, and large speed ratio, miniaturization and light weight are taken into account.
