A wheelchair with adjustable wheels build for production at a wheelchair factory in Guatemala. Applied Modeling Exam, 48 h, spring 2012. The rubber tires are the same as the ones used in off-road bikes, and when angled makes the chair suitable for use in sports. Users can change the angle of the seating by moving the support wheel at the back forwards or backwards. I made the CAD-model made in SolidWorks based a concept sketch.
