An electric motorcycle in which the disposition space of a motor is downsized, the number of components is reduced, and the power transmission efficiency is improved. In an electric motorcycle, a swing arm is swingably supported by a vehicle body frame and supports a power generating motor. A driving shaft of the power generating motor and a rear wheel axle of a rear wheel are coupled together. A driving force of the power generating motor is transmitted to the rear wheel. In the electric motorcycle, the driving shaft of the power generating motor is disposed generally in parallel to the rear wheel axle of the rear wheel. A driving gear is provided on the driving shaft. A driving gear is in meshing engagement with a reduction gear provided on the rear wheel axle. The driving gear has a smaller diameter than that of the reduction gear. A driving force of the power generating motor is transmitted to the rear wheel axle through a reduction.
