Morph Wheels
From: Noted at RESNA exhibit

The folding wheel was originally conceptualized as a folding bicycle wheel by
Duncan Fitzsimmons when he was a graduate student at the Royal College of
Arts in London. After receiving public attention and calls from the
wheelchair community telling him that this concept would be invaluable to
wheelchair users, he redesigned it as a wheelchair wheel.

Maddak further developed the wheel after careful consultation with the
community, and are happy to introduce MORPH Wheels - the world's first ever
foldable wheelchair wheel!
