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.
Manual selection of the pedalling cadence
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.
