Fixtures are attached to or integrally formed with the junction blocks for mounting of wheels or other conveyances or components to the frame assembly. A support structure is attached to the frame assembly to support a load such as a human or cargo or both. In a folded configuration, the frame members are moved into a generally parallel arrangement and the junction blocks and conveyances attached to the junction blocks or frame members are drawn together.
