The invention provides a two-gear speed changing and gear shifting structure of an electric two-wheeled motorcycle with a back-pushing function, which comprises a motor shaft, an output shaft, a low-speed gear disc gear and a low-speed gear secondary input gear, the low-speed gear disc gear and the low-speed gear secondary input gear are coaxially and fixedly connected, and the motor shaft is coaxially and fixedly connected with a low-speed gear input gear and movably sleeved with a high-speed gear input gear. The low-speed gear input gear is meshed with the low-speed gear disc gear, the motor shaft is further connected with a clutch capable of being meshed with or separated from the high-speed gear input gear, the output shaft is connected with a low-speed gear output gear, the low-speed gear output gear is meshed with the low-speed gear secondary input gear, and the high-speed gear output gear is meshed with the high-speed gear input gear. Any one of the low-speed gear disc gear, the low-speed gear secondary input gear, the low-speed gear input gear and the low-speed gear output gear is a one-way gear, and any one of the high-speed gear input gear and the high-speed gear output gear is a one-way gear. The two-gear speed changing and gear shifting structure is beneficial to rapid gear shifting of high and low gears of the electric two-wheeled motorcycle and reverse pushing of the motorcycle.
