I bought one and ended up not even making a wheel from it. It was brutally heavy and just playing around with it I could see it would be power-robbing. On that bike I stuck with my shimano 7 speed internal gear hub.
For high-end mountain bikes, makers are actually experimenting with removing gears from internal gear hubs[1] because for less mass, they want to keep the full range of gears but use less in the middle.
[1] They are not very common but there are some high end downhill bikes that use an internal gear hub, located near the bottom bracket. They are simply too heavy and expensive to appear on other types of bikes.
- Xylakant 4y agoI had an electric cargo bike with a nuvinci, since it was the only option with a belt drive. It works for that application, shifting under load is a nice thing when going up the hill with a heavy bike. But the downsides are pretty big. It’s lossy, so riding the bike without assist was tedious. The gear range is tidy, so I was always missing some on the upper end. I picked a different combination for the next bike.
