5.2.4.2 Warning heart rate

Under the sub-item "Warning heart rate", you can set your
optimal warning heart rate. You can set this to a value of
between "Target heart rate + 5" and "Target heart rate +
20" by using the two arrow buttons on the control panel.
Pressing the Set button confirms your selection and then
takes you back to the menu sub-item display.
With a target heart rate in the range of the basic
endurance, a warning heart rate of 10 beats (target
heart rate + 10) is recommended. This means: If the
target heart rate is exceeded by 10 beats, an acoustic
warning signal sounds immediately, which repeats
every six seconds. If the target heart rate is exceeded
by 15 beats, two acoustic warning signals sound,
which repeat every five seconds. If the target heart
rate is exceeded by a minimum of 20 beats, three
acoustic warning signals sound, which repeat every
four seconds.

As soon as you operate the twist-grip shifter or start
riding, the NuVinci Harmony gears switch on. Now decide

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.
6.1 Automatic mode
Set the desired pedalling cadence using the twist-grip
shifter. 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 becomes. The number of boxes lit up in blue de-
creases. 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 pedal-
ling cadence.
