A heat dissipation structure of an axle shaft for a power wheel of an electronic motorcycle comprising: a shaft body (10) and a thermal conduction element (20). The shaft body (10) is a hollow tube, a first end of the shaft body (10) is in connection with a frame unit of the electronic motorcycle, the thermal conduction element (20) is fitted with a second end of the shaft body (10), and the shaft body (10) is connected with of a support rack (32) of a stator of a hub motor. The support rack (32) has a bushing (322) formed on a central axle thereof and configured to accommodate the shaft body (10). The thermal conduction element (20) is made of thermal conductive metal and includes a first tubular section (22) and a second tubular section (24) connecting with the first tubular section (22) by using a connection portion (26). The shaft body (10) is connected with the first tubular section (22) via the second tubular section (24), and the second tubular section (24) is fitted into the bushing (322)
