13. Bicycle Gears

Ask for detailed instructions regarding
the operation and the special features of
the e-bike's gear system from your
FLYER specialist retailer, even if you are
an experienced cyclist. Practise on an
even and safe terrain. If you have any
questions about assembling, maintain-
ing, setting up or operating the gears,
please contact your FLYER specialist
retailer. Read the operating instructions
on the website of the respective manu-
facturer.
1. Despite a perfectly set up chain gear
system, a bike chain crossing at an an-
gle can lead to noises during riding.
These noises are normal and do not
cause any damage to the gear compo-
nents.
2. Do not pedal backwards while chang-
ing gears, as this may damage the gear
system.
Using faulty, incorrectly set-up or worn
gear components is dangerous and can
lead to falls. If you are concerned, have
components checked and readjusted as
required by a FLYER specialist retailer.

13.1 Electronic gear system

The electronic gear system differs from a me-
chanical system in, among other things, its main-
tenance and settings and its different program-
mable modes. To familiarise yourself with all of
the possibilities offered by this gear system, ap-
proach your FLYER dealer for in-depth informa-
tion. To be able to use and make the most of all of
the advantages of this modern gear system, also
read the enclosed operating instructions provided
by the component manufacturer.

Bicycle chain maintenance
Bike chains become worn with use. The degree of
wear varies considerably. Have the chain of your
FLYER regularly checked by your FLYER spe-
cialist retailer.
• Hub gears: approx. 3000 km
• Chain gears: 1500-2000 km
A worn bike chain can break and cause
very serious falls. Worn bicycle chains
must therefore immediately be changed
by your FLYER specialist retailer.
Regularly care for your bicycle chain by cleaning
and greasing it. These measures reduce prema-
ture wear.
To ensure that the chain and gears can
work safely, the chain must have a cer-
tain level of tension. Chain gear systems
tense the chain automatically. In the
case of hub gears, chains which are too
loose must be tightened. It might other-
wise jump off the gears and lead to a fall.
