MODEL RELEASED. Pavement-mounting wheelchair. (Image 2 of 2). View of a man in a pavement- mounting wheelchair. The wheelchair was brought up until the curved bar on its front was pressed against the pavement. Then, using a hand-operated switch, the front wheels have been lifted onto the pavement while the wheelchair rests on this bar and its back wheels. This is a motorised or powered wheelchair.
