Harmony intelligent drivetrain features the choice of two controller versions — Base and Advanced — to optimize the ride with increased comfort, safety and fun.
For riders who do not like shifting or for those who just prefer simplicity, the Harmony Base Controller intelligently manages the ride by automatically maintaining the pedaling cadence the rider chooses, with push button (automatic-only) shifting with three cadence settings (typically slow – medium – fast). e-Bike manufacturers will pre-set the cadence choices reflecting their bike and gearing specifications.
The Harmony Advanced Controller offers both fully automatic and manual shifting options. In "Automatic" mode, Harmony automatically and continuously adjusts the drive ratio to maintain the rider's preferred cadence. The rider is able to select and seamlessly maintain a cadence set-point by twisting the shifter. Pressing a "mode" button switches to "Manual" operation. The rider is then able to directly control the NuVinci CVP ratio manually. The Harmony Advanced Controller provides an attractive visual display of mode and setting similar to that of the NuVinci N360 controller.
