NuVinci Harmony brings automatic shifting to e-bikes
NuVinci Harmony brings automatic shifting to e-bikes: "Fallbrook Technologies released the NuVinci Continuously Variable Planetary (CVP) N170 transmission for bicycles in 2007. The rear hub-based system does away with distinct, defined gears, it's sealed against dirt and other contaminants (unlike a derailleur), and it allows riders to change drive transmission ratios even when standing still."
