Don't Worry About Shifting:
The Harmony System Will Do It for You          

The Harmony product groups (Harmony 330 and Harmony 380) add an additional element of comfort to the technology of the continuously variable transmission. This is because the Harmony system offers the first automatic continuously variable shifting system to those who'd rather not worry about shifting at all. You set your preferred cadence, and the transmission is controlled automatically so that you can always pedal at the same pace, even up or down hill. The gear ratio is always at the optimum setting, which also extends the range of your e-bike battery.  

You have a choice: Using the small, easy-to-operate H3 controller, you can choose between three preset cadences (slow, medium, and fast). The H8 controller (only available for the N380 hub) allows you to set the cadence yourself (with stepless shifting, naturally) using the impressive LED display. If you want to take over, you can turn off the automatic shifting with the press of a button. 

Features of Harmony 330 and Harmony 380:

Stepless shifting 
Effortless shifting, even under load
Greater gear ratio range than many conventional shifting systems
Comfortable pedaling at your desired preset cadence
Improved range for the motor of your e-bike
