To ensure that the chain and gears can
work safely, the chain must have a cer-
tain level of tension . Derailleur gears
tension 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.
10-15 mm
The axle nuts must be correctly fastened
after each chain adjustment process .
Work may only be performed on the
chain once the electrical system has
been switched off and the battery has
been removed . If the chain of your
FLYER e-bike has fallen off the chain
ring or sprocket, it is essential to switch
off the electrical system and remove the
battery before placing the chain back on
the gear wheels .
Chain care
The drive chain must be cleaned and lubricated
regularly in order to ensure that it functions well
(see section "Inspection plan") .
Dirt can simply be washed off. You can also clean
the chain by wiping it with an oil-soaked cloth .
Once it is clean, it must be lubricated at the joints
with a suitable lubricant . After leaving for a short
while, wipe off the excess lubricant.
Belt drive
The Gates Carbon Drive belt is very durable and
long-lasting. However, you must take extreme
care before and during assembly to ensure that
no damage is caused to the carbon fibres that
make up the strength of the drive belt. Extreme
bending and twisting causes tears that can lead to
faults in the belt if subjected to high stress .

Follow the instructions for handling the Gates
Carbon Drive System belt and observe the provi-
sions in the user manual .

The carbon fibres inside the drive belt may also
be damaged . If the drive belt slips through, take it
to a specialist to be checked .
If the tension of the drive belt is too high, bearings
and seals in the wheel hub can become dam-
aged . The wear and friction losses on the entire
drive are therefore also higher .

Adjusting the tension and alignment of
the belt requires a great deal of experi-
ence . Improper handling can cause acci-
dents and severe falls . Always let your
FLYER specialist retailer perform this
activity .
If the tension of the drive belt is too low,
this can cause it to slip on the toothed
pulley . This may result in accidents or
severe falls .
The carbon fibres inside the drive belt
may also be damaged . If the drive belt
slips through, take it to a specialist to be
checked over .
If the tension of the drive belt is too high,
bearings and seals in the wheel hub can
become damaged . The wear and friction
losses on the entire drive are therefore
also higher .
