Some embodiments are directed to a foldable vehicle for use as a vehicle if being unfolded, and for use as a trolley if being folded. The vehicle in its folded configuration may also be placed in an upright parking position. The vehicle includes a first side frame coupled to a first wheel, a second side frame coupled to a second wheel and a coupling frame. The coupling frame includes a hinge joint between a first end and a second end of the coupling frame. The first end is hinged to the first side frame and the second end is hinged to the second side frame. When the first wheel translates towards the second wheel, the hinge joint moves from one side of the second wheel to the other side of the second wheel.
