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 shit 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
shiter.
The pedalling cadence is the number of crank revolu-
tions within a speciic period of time when riding.
You can choose between 12 diferent pedalling cadences.
The urther forward you move the twist-grip shiter, the
faster the pedalling cadence becomes. The number of
boxes lit up in blue increases. The urther back you move
the twist-grip shiter, 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.

8.2 Manual mode
Set the desired pedalling cadence using the twist-grip
shiter. You can choose between 12 diferent pedalling ca-
dences. The urther forward you move the twist-grip shit-
er, the faster the pedalling cadence becomes. The number
of boxes lit up in orange increases. The urther back you
move the twist-grip shiter, the slower the pedalling ca-
dence becomes. The number of boxes lit up in orange de-
creases. The orange LEDs indicate the exact setting.
Manual selection of the pedalling cadence
You cannot shit through the entire gear ratio range
of the NuVinci Harmony gears when the bike is sta-
tionary. If you shit between gear ratios with a large
diferential when the bike is stationary, the Harmony
system will wait for the pedals or the bike to move.
