I read this on Wired the other day and it doesn't seem to have been picked up by the cycling press. Could be interesting if they can get the weight down further...
Breezer Uptown Infinity
But the Breezer has an ace up its sleeve. At the back end of the drivetrain sits a Fallbrook Technologies NuVinci N360 “seamless shifting” hub.This thing is a marvel. It’s a continuously variable transmission hub. Instead of offering a fixed selection of gear ratios that you mechanically shift between — as in other multispeed hubs — the NuVinci just glides up and down through the range of the transmission as you twist the grip shifter. It uses a circuit of freely rotating spheres instead of a standard planetary-gear system.
