Air bubbles in hydraulic disc brakes
Avoid permanently braking for long
periods, as can be the case during
long, steep descents. Otherwise,
bubbles may form and a total failure of the
braking system may occur. Severe falls and
injuries may result.
The brake lever may not be applied
if the pedelec is on its
side or upside down. Otherwise air
bubbles can enter the hydraulic system
which could cause the brakes to fail. After
transporting the pedelec, check if the pres-
sure point of the brakes seems softer than
before. Then slowly apply the brake a few
times. By doing this, air can be discharged
from the brake system. If the pressure point
remains soft, please do not use your pedelec
and ask a specialist to remove the air from
the brake.

You can avoid this problem by ap-
plying the brake lever before trans-
porting your pedelec and then fixing
it in this position using a strap. This prevents
air from entering into the hydraulic system.

Gear change

This operating manual describes
the use of common commercial
gear components on a pedelec as
an example. If your components are differ-
ent, you will find specific information in the
respective operating manual or on the web-
site of the manufacturer.
If you have any questions about as-
sembling, maintaining, setting up or
operating the gears, please contact
your specialist retailer.
The gear shifters regulate the necessary cycling
power and speed. Using lower gears makes cy-
cling uphill easier and reduces physical exertion
when pedalling. While riding in higher gears,
more physical exertion is needed to pedal, allow-
ing you to reach higher speeds with lower pedal-
ling cadence.
In general, you should strive to ride at a higher
pedalling frequency and in lower gears.
Modern pedelecs can be equipped with a variety
of different gear systems.
