To provide a two-wheeled vehicle enhancing responsiveness during acceleration/deceleration.
The two-wheeled vehicle 1 comprises a vehicle body 2, and wheels 3A, 3B (the wheel 3B is not shown) arranged coaxially on right and left sides of the vehicle body 2, and the center of gravity G of the vehicle is located below the center S of the wheels 3A, 3B. Two driving motors for rotating the wheels 3A, 3B, a front auxiliary wheel 8, and a rear auxiliary wheel 10 not brought into ground contact with a road surface R in a normal condition, and auxiliary wheel ground contact motors 11, 12 for vertically moving the front auxiliary wheel 8 and the rear auxiliary wheel 10 are provided on the vehicle body 2. The two-wheeled vehicle 1 has an ECU which controls the auxiliary wheel ground contact motor 12 so that the rear auxiliary wheel 10 is moved downwardly during the sudden acceleration and brought into ground contact with the road surface R based on the detection value of an accelerator opening sensor, and also controls the auxiliary wheel ground contact motor 11 so that the front auxiliary wheel 8 is moved downwardly during the sudden deceleration and brought into ground contact with the road surface R.
