1. System Functionality

The Automatic system provides automatic shifting for the rider at all times. It can be utilized with either the 3-button option, which makes automatic shifting as simple as pressing a button (2,3,4) to choose your pedal cadence or the grip shifter, which offers both fully automatic and manual shifting options. With the grip shifter the rider has the option to switch between “manual” and “automatic” modes by pressing the “mode” button (6) on the controller housing. The NuVinci Optimized™ internal gear hub can not be shifted completely through the ratio range while stationary. The Automatic system will intelligently wait for pedaling or wheel movement if wide ratio ranges are commanded while stationary.

2. Setup

[F] 3-BUTTON CONTROLLER

On the 3-button controller the pre-settings are completed through the desktop software at the retailer. Typically the 3-buttons are assigned (slow (4), medium (3), and (2) fast (2)) according to the bike type and gearing specification.

[F] + [G] GRIP SHIFTER

In automatic mode the system automatcally adjusts the ratio to maintain the rider´s preferred cadence.
The rider can shoose their ideal cadence setting by rotating the grip (1). The blue LED “RPM” display
indicates the cadence setting (9). In manual mode the rider is able to shift on their own electronically. Like the manual controller the steeper the “hill” on the LED display (8), the lower the ratio for climbing.

3. Calibration

On the first set up or after system maintenance or incorrect functionality the system has to be
calibrated.

[H] 3-BUTTON CONTROLLER

1. Turn system power on.
2. Pedal the bicycle lightly through the entire calibration process (preferable on a stand with the rear heel off the ground).
3. On the 3-button controller (1), press and hold the top (2) and bottom (4) buttons simultaneously until the rear hub begins shifting (5-7 seconds), then release the buttons.
4. Continue to pedal lightly through the entire calibration procedure, while the system shifts from “low” to “high” ratio multiple times and completes calibration.

[I] GRIP SHIFTER

1. Turn system power on.
2. On the Grip shifter controller (5), press and hold the “mode” button (6) until the rear hub begins shifting (5-7 seconds), then release the button. 3. Pedal the bicycle lightly through the entire calibration procedure (preferable on a stand with the rear wheel off the ground), while the system shifts from “low” to “high” ratio multiple times and completes calibration.
