Power-assist modes

You can choose between the power-assist modes ERGO,
POWER, SPORT and ECO ( Chapter 5.1.4 "Display of the
power-assist mode").
In the power-assist mode ERGO, the assistance provided
depends on your heart rate.
In the power-assist modes POWER and SPORT, the as-
sistance works with a high or medium level of efort. Of
course, the range is reduced as a consequence.
The ECO mode provides you with harmonic, gentle as-
sistance and a long range. It is advisable for beginners or
inexperienced riders to start with this mode.
If you wish to make any urther adjustments to the
ride characteristics of your bike, please consult your
specialist cycle shop.

Range

The distance you can travel using the power assist with
the battery ully charged depends on several factors:
• Selected assist level
If you want to cover a large distance with power
assist, select the smaller gears, i.e. the ones that
are easier to pedal. Also select a low assist level
(ECO).
• Handling
If you are riding in gears that are harder to pedal
and select a high assist level, the motor will pro-
duce plenty of power to help you along. However,
just as with driving a car at high speed, this leads
to higher consumption. You will therefore have
to recharge the battery sooner. You can conserve
energy by keeping the load on the pedals even
throughout the entire crank revolution.
• Ambient temperature
If it is colder, you will travel a shorter distance
with the same battery charge.
To maximise the distance you can travel, keep the
battery in a heated room so that it is at room tem-
perature when you it it on your Pedelec.
As the battery discharges when the motor is in use,
it generates enough heat to not lose too much of
its power at low ambient temperatures. The bat-
tery cells can discharge at temperatures of -15 to
+60°C. This is also the temperature range within
which you can use your battery.
• Technical condition of your Pedelec
Make sure the tyre pressure is correct. If you ride
your bike with too little air in the tyres, this can
signiicantly increase the rolling resistance. This
applies to smooth surfaces in particular, e.g. tar-
mac. If the ground is uneven, as on a country path
or gravel track, a somewhat reduced tyre pressure
can lead to less rolling resistance. This also in-
creases the risk of a puncture. Please consult your
specialist cycle shop about this. The distance you
can travel also decreases if the brakes are rubbing.
• Battery capacity
The current battery capacity
( Chapter 8.4.2 "Checking the battery capacity").
• Topography
You pedal harder when riding uphill. This is de-
tected by the power sensor which then allows the
motor to work harder.
Under ideal conditions, the range may reach 120 km with
the 11 Ah battery and 205 km with the 17 Ah battery.
These ranges have been achieved under the conditions
listed below.
