A man in a wheelchair shows his AMAZING invention !

The introduction of the wheelchair, dated no earlier than the 15th century, has certainly revolutionized the lives of people with mobility problems, but much more can be done in terms of freedom of movement; very different floors in fact require the use of specific wheels, and the man you see in the video knows it well: he obtained a patent during the Abilities Expo 2011. Thanks to an additional wheel easy to assemble and store, you may have the opportunity to venture on places that would be inaccessible with ordinary small wheels .
