7. Pressing the Set button will take you back to the menu
sub-items.
8. Now you can adjust the settings further under the
other menu sub-items (➠ Chapter 5.2 "Setting and pro-
gramming the display") or navigate to the item "Back"
using the arrow buttons.
Pressing the Set button takes you back to the main
menu.
9. Now switch your NuVinci Harmony gears to automatic
mode. As soon as you move the twist-grip shifter, the
gears switch on. Press the motor symbol on the mode
button.
Automatic selection of the pedalling cadence
In order to effectively maintain a steady heart rate
whilst riding, we recommend the automatic 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.
10. Set the desired pedalling cadence using the twist-grip
shifter. 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 decreases. 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 pedalling cadence you have set.
When the bike is stationary, you cannot switch from
minimum to maximum pedalling cadence, or vice
versa. You can only do this whilst riding.
11. You can now ride off just as you would if you were
riding a normal bike. The motor starts providing assis-
tance as soon as you begin to pedal.
From the first moment on, you have full assistance.
This is unfamiliar but comfortable. Practice starting
up in a safe location before venturing into the road
traffic.
› As you begin your ride, it is highly probable that
your actual heart rate is below your target heart
rate. You receive very little assistance from the
drive or none at all. You move your Pedelec ei-
ther totally or almost exclusively by means of
your own effort. As a result, your heart rate rises
and you keep moving closer to your target heart
rate. If you have reached your target heart rate
or even exceeded it, the motor provides assis-
tance according to the riding situation. You can
call up the output delivered by your motor in the
information area ➠ Chapter 5.1 "Basic functions".
