A coaxial two-wheel vehicle with which a rider stably travels without the upper body being swayed left and right in a riding state of the center of gravity being positioned high. The coaxial two-wheel vehicle includes: a step plate for a driver to ride; a vehicle body that supports the step plate to be capable of changing a posture in a roll direction of rotating around a roll axis as the center, when a traveling direction is made the roll axis; a pair of wheels with one wheel disposed on each side of the body on the same axis in the direction orthogonal to the traveling direction of the vehicle body and rotatably supported by the vehicle body; a pair of wheel drive means to drive and rotate the pair of wheels independently; and a handle for directly changing a posture of the step plate or indirectly changing the posture through the vehicle body.
