A wheel chair that is also an all-terrain trike. The arms ratchet the wheel gears forward. It could use a motor on a Jack-shaft or two hub motors but you won't get any exercise that way. http://www.mountaintrike.com/

There are a lot of “concept” vehicles. Most never get funded because the designers have no knowledge of what it takes to actually build one. I would like to see more concepts deigned by engineers! http://www.lovethesepics.com/

This one is for people who still have the ability to use their legs? There’s a version of this wheelchair that is steered only with the arms, but we couldn’t find any images of it. http://www.customfaucets.com/services.html
