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 40 and 80 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.
