6.2 Manual mode
Set the desired pedalling cadence using the twist-grip
shier. You can choose between 12 dierent pedalling ca-
dences. The rther forward you move the twist-grip shi-
er, the faster the pedalling cadence becomes. The number
of boxes lit up in orange increases. The rther back you
move the twist-grip shier, 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 shi through the entire gear ratio range
of the NuVinci Harmony gears when the bike is sta-
tionary. If you shi between gear ratios with a large
dierential when the bike is stationary, the Harmony
system will wait for the pedals or the bike to move.
