Fallbrook Technologies have introduced some pretty successful e-bike shifting systems over the past few years. The newest system from Fallbrook Technology is pretty impressive, and much better compared to its predecessors. It is called the NuVinci Harmony, which is an automatic shifting system designed for electric bike technology.

The NuVinci Harmony operates with the NuVinci’s N360 Continously Variable Planetary (CVP) drivetrain. The Harmony is built as a separate unit and mounts inside the rear dropout, pulling power from any electric bike battery from12-48 volts DC. For those e-bikers who tend to leave their bikes in one constant gear, which can overwork the electric motor, this automatic shifting system is just the solution.

 

There are two NuVinci Harmony models – advanced rider and basic rider. With the advanced rider controller, you are able to find exact cadences and set the cadence of your liking. Then, the system will make adjustments according to the wind changes or terrain so that the cadence can be maintained. Riders also have the option to switch to manual mode to adjust the ratio manually. On the other hand, controller for the basic rider is of a much simpler set-up, and there are 3 programmable settings – slow, medium and fast, that can be pre-set.

The hub interface of the Harmony system weighs around 250 grams, with a quick-release attachment to enable easy wheel removal. You will be seeing the NuVinci Harmony CVP system on electric bikes early next year, with a price range of EUR 2,000 and above.
