I like how the Swincar has a roll-cage.

Even if the "Not a wheelchair" has a lower speed, and less off-road capabilities than the Swincar, it still seems like roll protection could be a useful safety system.

I guess they're relying on the light[er] weight?

Your comment reminded me of a motorcycle racer I knew who was paralyzed from the waist down. He had a few funny stories about coming off his bike and having his legs broken and bent like a pretzel. The track martials would come over and just about faint at the sight of it, he often had to calm them down. He'd get looked over by the medics and drive himself to the hospital to get a cast put on.

That really can't be healthy for him, can it??

It's not something you should do deliberately for sure. Because he wasn't able to move his body weight on the bike the bike had to lean even further than any other rider so he was often very close to the edge. He also always had to start from the back because he had to have people to launch him.

They might be able to sell a roll cage as an add-on. Probably most people won't need that but might be good for some. It looks like the frame would be simple to mount to.
