The invention discloses a bow disc type two-gear self-adaption automatic speed change drive assembly of an inner rotor motor of an electric motorcycle. The assembly comprises a drive motor, a box and a transmission shaft, wherein the drive motor is an inner rotor motor. The assembly further comprises a slow-gear transmission mechanism, and a mechanical intelligent self-adaption speed change assembly arranged on the transmission shaft; the axial end surface of an outer ring of an overrunning clutch of the slow-gear transmission mechanism is formed to an annular recess; an inner ring is rotationally matched in the annular recessp; and an engagement space is formed between the outer circle of the inner ring and the inner wall of the radial outer side of the annular recess. The assembly prevents an inner ring on a traditional structure from being directly supported on the transmission shaft, and prevents the problem of increment of a transmission error on the overrunning clutch, so that the whole stability of the overrunning clutch is guaranteed, the stable support is still guaranteed in long-time operation of a transmission, the operation noise is reduced, the operation comfort is guaranteed, the transmission efficiency is improved, and the energy consumption is reduced; and the assembly prolongs the service life, improves the operation precision, and is suitable for use environments of heavy load and high speed.
