SuperFour-Prototype   SuperFour - can't fly

The SuperFour is the first outdoor wheel-chair featuring all-wheel-drive and all-wheel-steering. Otto Bock GmbH succeeded to redefine the autonomy and individual freedom for people with limited mobility. The SuperFour features four-wheel-drive powered by hybrid technology which enables an enormous climbing ability and a very wide range. All-wheel-steering, a navigation system, single-wheel suspension, automatic seat-tilt, seat-position adjustment, halogen lights and weather protection help to improve the comfort of wheel-chair user. Urs Schönauer, the designer of the SuperFour, managed to integrate all these features in an elegant appearance. ESORO was responsible for the development and manufacturing of this fully functional concept chair and realized the SuperFour in only 3 months. The SuperFour was presented to public during the Reha Care 2004 in Düsseldorf.
