The invention relates to a middle motor power-assisted multi-gear speed change mechanism which comprises a shell, a first main shaft, a second main shaft, a treading shaft, an automatic centrifugal speed change mechanism, a power output wheel, a machine core assembly and a treading piece, the treading shaft is arranged on the shell and can rotate relative to the shell, the automatic centrifugal speed change mechanism is arranged on the first main shaft in a sleeving mode, and the automatic centrifugal speed change mechanism is arranged on the second main shaft in a sleeving mode. The automatic centrifugal speed change mechanism comprises a speed change mechanism input part, a speed change mechanism output part, at least two sets of planetary transmissions and at least two sets of automatic centrifugal gear shifting assemblies, and the speed change mechanism output part protrudes out of the shell. The power output wheel is arranged on the portion, protruding out of the shell, of the speed change mechanism output piece, the machine core assembly is provided with a machine core assembly output piece, and the treading shaft and the machine core assembly output piece are in transmission connection with the speed change mechanism input piece, so that the structure of the speed change mechanism is greatly simplified, and the manufacturing difficulty of the speed change mechanism is reduced.
