The invention discloses a lateral-hung bow disk type two-gear self-adaption automatic speed change driving assembly for an electric motorcycle. The lateral-hung bow disk type two-gear self-adaption automatic speed change driving assembly comprises a box body and a transmitting shaft; the box body comprises an installing portion which is laterally hung and installed on the hub side; and the lateral-hung bow disk type two-gear self-adaption automatic speed change driving assembly further comprises a slow-gear transmitting mechanism and a mechanical intelligent self-adaption speed change assembly arranged on the transmitting shaft. An annular groove is formed in an axial end face of an outer ring of an overrunning clutch of the slow-gear transmitting mechanism, an inner ring is arranged in the annular groove in a rotary and matched manner, and a meshed space is formed between the outer circle of the inner ring and the inner wall of the axial outer side of the annular groove. The lateral-hung bow disk type two-gear self-adaption automatic speed change driving assembly avoids a traditional structure that an inner ring directly supports the transmitting shaft and also solves the problem that transmitting errors are amplified on the overrunning clutch. Furthermore, the whole stability of the overrunning clutch is guaranteed, the stable support of the speed changer can be still guaranteed after a long-time operation, the operating noise is reduced, the running comfortableness is guaranteed, the transmitting efficiency is improved, and the energy consumption is reduced. In addition, the service life is prolonged, the operation accuracy is improved, and the lateral-hung bow disk type two-gear self-adaption automatic speed change driving assembly is suitable for the heavy-load using environment and the high-speed using environment.
