Therefore please always carefully switch into
the lowest gear or the largest rear sprocket if
you want to avoid damage.
21.1 Chain gears
This operating manual describes the use of
common commercial gear components on a
pedelec as an example.
If your components are different, you will
find specific information in the respective op-
erating manual or on the website of the manu-
facturer.
If you have any questions about assembling,
maintaining, setting up or operating the gears,
please contact your pedelec specialist retailer.
Contact your specialist retailer
if you have any of the following
problems:
• The chain comes off the sprockets or
the chain rings.
• Chain links, chain rings or sprockets
are broken or worn out.
• Changing gears does not work com-
pletely correctly.
Do not pedal backwards while
changing gears as this could
damage the gear system.
Changes to the setup of your gears
should only be made in small steps
and with the greatest of care. Incorrect
setup work can lead to the chain coming
off the sprockets and causing a fall. If
you are at all unsure, contact a special-
ist retailer who can set this up for you.
Despite a perfectly set up
chain gear system, a bike chain
crossing at an angle can lead to
noises during riding. These noises are
normal and do not cause any damage to
the gear components. With less angled
running of the chain in a different gear,
this noise will no longer appear.
• The rear derailleur or other gear shift-
ing components appear to be dam-
aged or loose.
• Unusual noises occur while changing
gear or riding.
21. Bicycle gears
Using faulty, incorrectly set up
and worn gear components is
dangerous and can lead to falls.
Therefore if there is any uncertainty,
please have the gears checked by a spe-
cialist and set up again if required.
The use of spoke guards is re-
quired. Otherwise, only minor
setup errors could lead to the
chain or the entire rear derailleur falling
between the sprockets and the spokes.
