I
met these four young fellows sharing one wheelchair, and they had
already redesigned that wheelchair. They had ridden it so hard that it
had broken in 20 different places. They had reinforced it, welded it
all back together, and made it much stronger than it had been. And they
knew so much about good wheelchair design. It was clear they were the
people I was looking for to help me, and I could help them as well, so
we’ve been working together ever since. (Hotchkiss, 2011)
