Setting the assistance level

sistance you want the eBike drive to provide you with
while pedalling. The assistance level can be changed
at any time, even while cycling.
Note: In some models, the assistance level may be
preset and cannot be changed. There may also be
fewer assistance levels available than stated here.
The following assistance levels are available as a max-
imum:

can just be moved by pedaling, as with a normal bi-
cycle. The push assistance cannot be activated at
this assistance level.
– ECO: Effective assistance with maximum efficiency,
for maximum range
– TOUR: Steady assistance, long range for touring
