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.
이륜차체, 이륜차체의 전후방에 회전 가능하게 장착되는 전방바퀴 및 후방바퀴를 가지며, 조향장치에 의해서 전방바퀴가 조향되는 이륜차는, 이륜차체의 양측에서 전방바퀴에 연결되며, 전방바퀴를 조향하는 조향장치에 의해서 전방바퀴와 동일한 회전 중심으로 함께 조향되는 보조바퀴, 지면으로부터 보조바퀴의 상하간격을 조절하도록 보조바퀴를 상하 이동시키는 승강장치, 및 이륜차체로부터 보조바퀴의 좌우간격을 조절하도록 보조바퀴를 좌우 이동시키는 간격조절장치를 포함할 수 있으며, 주행 시 보조바퀴가 지면에서 이격되어 보조바퀴에 의한 주행 방해를 막고, 회전 주행 시 발생하는 이륜차체의 기울기는 보조바퀴가 지면에 접지되면서 제한되어 이륜차체가 일정 각도 이상 기우는 것이 방지된다.
