Duncan Fitzsimons has designed an incredibly innovative wheelchair which greatly enhances it’s portability. In a previous line of work my main clients were in various types of wheelchairs and moving them in and out of vehicles was a logistical nightmare. Each wheel would have to come off and then all the pieces put into the trunk like a game of tetris. The biggest issue of course was the large wheels which not only took up a lot of space, but were often dirty from the winter roads.
Here we have a new design where the wheel collapses, and apparently is the same weight as a solid wheel. I’d be curious to know what type of tire is on the chair? I would assume an inflatable one would not work so maybe it is a solid rubber compound?
