Abstract: A vehicle and in particular a scooter in which there is present a first and a second element separated from each other and movable relative to a base frame, the elements defining respective actuating surfaces disposed substantially in side by side relationship with each other with respect to a longitudinal extension axis of the vehicle; an alternated operation of the first and second movable elements (6, 7) allows a motion-transmitting unit (8) to convert the reciprocating motion into a rotatory motion imparted to one of the scooter wheels thereby causing advancing of the vehicle. The particular positioning and configuration of the movable elements (6, 7) allows a steady and efficient use of the scooter.
