Automatic shifting for e-bikes

Fallbrook Technologies has announced it’s latest incarnation of their ‘transmission for bicycles’ technology – the NuVinci Harmony – which is an auto-shifting version of the N360 aimed specifically at e-bikes.

The Harmony, which is intended for use with 12-48 volt e-bike systems, automatically adjusts the drive ratio in order to maintain the cyclist’s preferred pedalling cadence. If you’re going up a hill, for instance, it will shift into a lower ratio, so that it’s no more difficult to turn the pedals than it was on the flats.

There are two handlebar-mounted controllers available for the system. The Base Controller simply allows riders to chose between three speeds of automatically-maintained cadence, with the push of a button. These will be preset by the e-bike manufacturer itself, as dictated by the gearing and other parameters of the bike. Typically, however, the cadence choices would consist of fast, medium and slow.
