The lightest folding wheelchair in the world: http://quickie.sunrisemedical.eu/ligh...
From just 8.8kg and with a new unique crossbrace combined with the completely redesigned axle stem, the QUICKIE Xenon² is a ultralightweight wheelchair that’s easy to fold, lift and transport. It's been cleverly designed to create the kind of minimalistic style that you'd expect from a rigid, active wheelchair. With a fixedfront frame for a clean, streamlined design, and innovative technology, the Xenon² FF is the ideal match for those with a very active lifestyle who demand an ultralightweight yet stiff wheelchair for maximum driving performance.
