I don't know why you are getting down-votes. If you've spent any time around a motorized wheelchair you would see they are still pretty bad tech.

The wheelchair companies were not the ones who managed to produce the e-bikes and e-scooters, even though they seemed well placed to do so.

It's actually taking an e-bike and turning it into a wheelchair that looks a lot more like the future and not a "dongle" (plus the creator has first-hand knowledge of disability): https://www.youtube.com/watch?v=vuMg0QwKAGI
