A vehicle operable to move by inverted pendulum control, comprising: a rider seat on which a rider can ride: a chassis disposed below the rider seat: a wheel rotatably attached to the chassis; a first drive unit operable to rotationally drive the wheel; characterised by a first rotationally movable bar protruding forward beyond the chassis; a second drive unit operable to rotationally drive the first rotationally movable bar with respect to the chassis; a footstep rotatably supported on the first rotationally movable bar, on which a foot of the rider can be put; a second rotationally movable bar protruding backward beyond the chassis; a third drive unit operable to rotationally drive the second rotationally movable bar; and a control unit operable to control the second and third drive units, wherein the vehicle is operable to move in an inverted state in which the footstep and the second rotationally movable bar are away from the ground and the wheel is in contact with the ground, wherein the rider can get on/off the vehicle in a stable state in which the footstep, the second rotationally movable bar and the wheel are in contact with the ground, wherein the control unit is operable to change the vehicle to the inverted state from the stable state by raising the footstep so that the footstep moves away from a ground, or to change the vehicle to the stable state from the inverted state by lowering the footstep so that the footstep touches the ground, and wherein in at least one of a situation where the vehicle is changed to the inverted state from the stable state and a situation where the vehicle is changed to the stable state from the inverted state, the second and third drive units are driven in synchronization with each other so that the first and second rotationally movable bars are simultaneously rotated. a rider seat on which a rider can ride: a chassis disposed below the rider seat: a wheel rotatably attached to the chassis;
