To improve cooling efficiency of an electric motor in an electric two-wheel vehicle compared to the prior art.SOLUTION: A wheel drive mechanism is configured to drive wheels with an electric motor such that the wheels rotate. An output shaft of the electric motor and an axle of the wheels are in an orthogonal relation. The output shaft and the axle are connected by using a predetermined power transmission mechanism. A drive circuit that electrically drives the electric motor is disposed at an upstream side of the electric motor in the flow direction of travel wind.SELECTED DRAWING: Figure 2
