<p>A two-wheeled vehicle has a two-wheeled vehicle body and a front and a rear wheel rotationally mounted in a front and a rear side of the two-wheeled vehicle body, wherein a front wheel is steered by a steering apparatus. The two-wheeled vehicle may comprise: an auxiliary wheel connected to a front wheel on both sides of the two-wheeled vehicle body and steered by the rotational center same as the front wheel in accordance with the steering apparatus steering the front wheel; a lifting apparatus vertically moving the auxiliary wheel for a vertical distance of the auxiliary wheel to be controlled from the ground; and a distance control apparatus laterally moving the auxiliary wheel for a lateral distance of the auxiliary wheel to be controlled from the two-wheeled vehicle body. When driving, the auxiliary wheel is spaced from the ground to prevent driving interference by the auxiliary wheel. An inclination of the two-wheeled vehicle body generated when rotationally driving is limited as the auxiliary wheel is in contact with the ground, thereby preventing the two-wheeled vehicle body from being inclined at more than a predetermined angle.</p> |
