8.2 Manual mode
Set the desired pedalling cadence using the twist-grip
shifter. You can choose between 12 different pedalling ca-
dences. The further forward you move the twist-grip shift-
er, the faster the pedalling cadence becomes. The number
of boxes lit up in orange increases. The further back you
move the twist-grip shifter, the slower the pedalling ca-
dence becomes. The number of boxes lit up in orange de-
creases. The orange LEDs indicate the exact setting.
You cannot shift through the entire gear ratio range
of the NuVinci Harmony gears when the bike is sta-
tionary. If you shift between gear ratios with a large
differential when the bike is stationary, the Harmony
system will wait for the pedals or the bike to move.
Automatic selection of the pedalling cadence
Manual selection of the pedalling cadence
Now decide whether you prefer manual or automatic
operation of the NuVinci Harmony gears. Press the mode
button to switch to the desired mode.
We recommend the automatic mode for riding in the
ERGO power-assist mode. Because as soon as you
start to ride in manual mode, you have to shift gear
manually to ensure that you do not exceed your target
heart rate.
8.1 Automatic mode
Set the desired pedalling cadence using the twist-grip
shifter.
The pedalling cadence is the number of crank revolu-
tions within a specific period of time when riding.
You can choose between 12 different pedalling cadences.
The further forward you move the twist-grip shifter, the
faster the pedalling cadence becomes. The number of
boxes lit up in blue increases. The further back you move
the twist-grip shifter, the slower the pedalling cadence be-
comes. The number of boxes lit up in blue decreases. The
blue LEDs indicate the exact setting. Once you have found
your ideal pedalling cadence, you can ride without even
having to change gear once. The automatic mode adapts
the gear ratio to the rider’s preferred pedalling cadence.
