Zusammenfassung:The utility model relates to the field of transmissions, in particular to a two-gear speed change structure, and aims to solve the problems that an existing transmission is complex in structure and power interruption occurs during gear shifting. In order to achieve the purpose, the two-gear speed change structure comprises an input shaft, a first-gear driving gear, a second-gear driving gear, a first-gear transmission shaft, a second-gear transmission shaft and a second-gear transmission shaft, the intermediate shaft is provided with a first-gear driven gear meshed with the first-gear driving gear, a second-gear driven gear meshed with the second-gear driving gear and a main reduction driving gear; the centrifugal automatic clutch I is arranged between the first-gear driven gear and the intermediate shaft; the centrifugal automatic clutch II is arranged between the second-gear driven gear and the intermediate shaft; one of the centrifugal automatic clutch I and the centrifugal automatic clutch II is a normall
