An electronic gear shifting multi-gear transmission assembly for a tricycle comprises a shell and a transmission device. The transmission device comprises an input gear shaft, a first transmission shaft and a second transmission shaft; a second-gear and third-gear shifting mechanism is arranged between the second-gear driving tooth and the third-gear driving tooth on the first transmission shaft and used for being connected with the second-gear driving tooth or the third-gear driving tooth, and a first-gear shifting mechanism is arranged on the second transmission shaft and used for being connected with the first-gear driven tooth; the first-gear shifting mechanism and the second-third-gear shifting mechanism are connected with the shifting fork driving mechanism through shifting forks respectively, the shifting fork driving mechanism comprises a shifting fork supporting shaft, at least two U-shaped supports and a shifting hub, the shifting fork supporting shaft is a fixed shaft, the U-shaped supports and the shifting forks are both arranged on the shifting fork supporting shaft in a sliding fit mode, the shifting forks and the U-shaped supports are axially positioned through positioning pins, and the shifting forks are arranged on the shifting fork supporting shaft. The gear shifting hub is provided with a guide cam groove extending in the circumferential direction, guide pins arranged at the top ends of the U-shaped supports are in sliding fit with the guide cam groove, the gear shifting hub is fixed to a rotating shaft, and the rotating shaft is driven by a gear shifting motor.
