Wheels4U is a low-cost do-it-yourself wheelchair for disabled children in the developing world. The project reuses daily objects like plastic washbasins and recycles discarded children’s bicycles and locally available materials. Its parts come in a box that acts as an instruction manual for the do-it-yourself creation of Wheels4U. The black outlines on the box indicate to users which additional components they’ll need to complete the product. By following the included instruction book, the parents of disabled children can easily assemble, adjust and repair their own wheelchairs by hand.
