Pedelec (as described in ➠ Chapter 1 "Quick start").
› You can also remove the battery from the holder
and charge it in the docking station. This is recom-
mended if it is cold outside, in order to charge the
battery in a warm room. The battery can be
charged at temperatures between 0 and 45°C.

Learning cycle

After fully charging the battery for the first time and
thereafter roughly once every six months, you must
run the battery down until the system switches off.
This procedure (a so-called "learning cycle") is nec-
essary so that the battery management recognises
the changes in the capacity caused by age and wear
and tear, in other words, the performance level of
the battery. Afterwards, the capacity of the battery is
calculated anew and correctly represented. With this
procedure, you can prevent a sudden loss of electrical
assistance during an extended trip.
