Portable transportation assembly

A portable transportation assembly comprising an assembly having a frame and wherein said frame having a certain width;

• a pair wheels;
• a pair of dissimilar axles which are attached to said frame in a spatially offset manner;
• a pair of members which are each connected to said pair of dissimilar axles and which are further connected to said pair of wheels;
• and an assembly which is coupled to one of said pair of dissimilar axles and which selectively rotates said one of said pair of dissimilar axles from a first position to a second position, effective to move said pair of wheels from a first operative and low position to a second raised and storage position, wherein said frame includes a selectively movable back bumper assembly and wherein said selectively movable back bumper assembly includes an L-shaped bracket member having a first planar portion coupled to and positioned upon a flat surface of said frame and wherein said first planar portion is parallel to said flat surface, and a second planar portion which is orthogonally positioned to said first planar portion and wherein said second planar portion having an aperture;
• a pair of substantially identical first and second hinges which are coupled to said frame and which protrude outwardly from said frame;
• an L-shaped back member which is linearly coextensive to said certain width and having a pair of substantially identical and orthogonally protruding third and fourth hinges;
• an axle which is coupled to said pair of substantially identical third and fourth hinges, and wherein said first hinge is coupled to said third hinge by said axle and wherein said axle traverses and extends through said first and said third hinges, and wherein said second hinge is coupled to said fourth hinge by said axle and wherein said axle traverses and extends through said second and said fourth hinges, thereby allowing said back member to be movable from a first open position to a second closed position;
• a pin member which is coupled to said back member by a spring member and which is adapted to be received by said aperture.
