  • Patent number: 10597104
    Abstract: A scooter has a foot rest arrangement with a left foot rest surface and a right foot rest surface, a steerable front wheel guide mounted in a head tube so as to be rotatable about a first axis of rotation, and a steering column that can be rotated about a second axis of rotation. The steering column and the front wheel guide are spaced apart from each other and are operatively coupled to each other to transfer a steering movement. The second axis of rotation intersects the foot rest arrangement at an intersection point in such a way that the left and right foot rest surfaces are arranged on either side of the intersection point.
