From the article:

> When I first heard about this, it sounded awesome and a bit far-fetched. It’s hard to find a pair of quality wheelchair wheels for less than $500. Same with a rigid backrest. How were they going to offer both, plus a custom wheelchair frame without compromising on quality?

I have no idea though. Maybe there are sort of like… different classes of wheelchair, and they are trying to make not-terrible one? Like technically $5 headphones exist but not from a hobbyist point of view.
