With a vehicle comprising a motor (5) and at least one rotatable element (1, 2; 10) which follows the ground, at least one rotatable element (1, 2; 10) is connected to a steering mechanism for controlling the direction of travel of the vehicle. The steering mechanism comprises means (11) for adjusting the momentary distance from the axis of rotation of at least a part of a rotatable element (1, 2; 1 0) to the ground or means for adjusting the momentary coefficient of friction of at least a part of a rotatable element (1, 2; 10). Thus, the vehicle has a simple steering mechanism. |
