12 VI User Manual | Impulse Ergo Pedelec
› Riding steadily for extended periods allows the
ERGO system to learn how you handle the bike
and adapt better to your own personal handling
style and the behaviour of your heart rate. It may
take some time to do so and the system must
“learn” these behaviours all over again if the
ERGO settings are readjusted.
› If you have run the battery all the way down
to empty, the system switches o completely.
When this occurs, the NuVinci Harmony gears
no longer nction either. Aer ve minutes, the
battery will have recovered and you can switch
the system back on again. The display nctions
once more. From now on, please only ride in the
mode “no assistance/stand by”. At this point
you can also operate the gears once more. In this
way, you can ride for another hour until the bat-
tery nally switches o. Attention: The battery
switches o as soon as you begin to ride using
the power-assist mode once more.
Observe the following points to avoid major short-
term variations in your heart rate:
› Pedal evenly with a constant level of eort.
› If you come to a hill, do not try to maintain the
same speed. But do try to maintain the same
level of physical eort. Of course, your speed
decreases as the incline becomes steeper
› Do not sprint when riding.
