Good point. I've known about NuVinci for quite a while.

Based on the operating principle, it seems to me the NuVinci would be
draggy, and online comments hint that it is. This site

claims only 83.5% efficiency (although I don't see the NuVinci curve in
their graph). 83.5% is really low.

Has anyone here ridden one?
