Operational range
and its factors
The range that can be attained with a fully
charged battery is dependent upon additional
factors such as incline, headwind, condition of
road surface, tyre pressure, use of gears as well
as the pedal assistance and the weight of the
driver.
Typical distance with an average use of pedal
assistance and a fully charged battery ranges
between 30 and 60 km according to the mode
selected.
It is practically impossible to provide absolute
data regarding the range as various factors
influence the assistance performance. To begin
with, the battery must be optimally charged. This
can be ensured by using the original charger,
through sufficient charging time, the age of the
battery as well as its continuous maintenance.
If all
these factors are favourable, i.e. the operating
temperature is also between 5 and 35 °C and a
full charge has taken place, then 37V x 8.8Ah =
325 Wh of stored energy should be available to
begin driving.
With the battery’s increasing age, the maximum
amount of stored energy can sink by a third and
in so doing the running distance too. On the
whole, lithium-ion batteries can experience up
to 500 full charge cycles, but through aging the
capacity will sink in due course down to 85 - 65
%. Providing good maintenance is taken, then
a life expectancy of approximately 3 – 5 years is
possible. The capacity will decrease slowly but
steadily.
Riding in rough terrain under extreme condition
may further reduce the range of travel. The
rechargeable battery can last through an approx.
90-minute trip under “full load”.
Opti-Range
To optimise the use of the battery capacity,
the mode will change automatically to the next
lower driving mode. This is based on the battery
voltage and it protects the cells against high
load. The higher mode is available after charging
the battery again. For e-bikes with Opti Range
the display will indicate “Battery Low”. The
remaining capacity is sufficient for approximately
2 hours to bike lights (LED lighting). After
charging the battery, all riding modes are usable
again. When attempted mode change N to S or
E to N at pedelec display the message “Opti-
range active”. If the battery is nearly empty the
engine switches off automatically.
