NuVinci Harmony brings automatic shifting to e-bikes

Fallbrook Technologies released the NuVinci Continuously Variable (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. Last year, the company unveiled the NuVinci N360, which is smaller and lighter than the N170, yet has a wider range of ratios. This Tuesday, Fallbrook announced yet another incarnation of the technology – the NuVinci Harmony, which is an auto-shifting version of the N360.
