The chain may only be tightened once
the electrical system has been switched
off and the battery has been remo ed. f
the chain of your FLYER e-bike has fall-
en off the chain ring or sprocket, it is es
-
sential to switch off the electrical system
and remove the battery before placing
the chain back on the gear wheels.
16. Brake
1. Brakes are safety components. Have
the setting and maintenance work per-
formed by your FLYER specialist re-
tailer. Only original spare parts may be
used. Otherwise it is possible that the
functionality of your FLYER e-bike may
be impacted or damaged. No modifica
-
tions of the brake system are permitted.
2.
The braking effect of modern brakes is
very strong. You must get used to the
braking performance of the new brakes.
Activate the brake carefully. You should
practise emergency braking in a safe,
tra c-free area so that you can safely
handle your FLYER even during very
intense braking manoeuvres.
3. On long downward sloping sections
you should not brake gently all the
time as this can cause the brakes to
overheat, thus causing braking per-
formance to fade or fail altogether.
Alternate between applying the front
and back brake on long and steep
downhill sections to allow the other
brake to cool. It is preferable to brake
sharply for a shorter time before tak-
ing bends or if you are riding too fast.
This allows the brakes to cool down
in the meantime. This preserves your
braking power. The only exception is if
you are cycling in slippery conditions
such as on sand or a smooth surface.
You should then exercise great care,
slowing yourself down using the rear
brake. Otherwise there is the risk of
the front wheel slipping out to the
side and causing a fall. Take regular
breaks during long downhill sections
to gi e the brakes su cient time to
cool down. Do not touch the brakes
for at least 30 minutes after riding as
they can become very hot.
4. Almost all modern brakes provide
considerably more braking power
than was available for bicycles in the
past. Carefully familiarise yourself

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. 000 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 ump off the gears and lead to a fall.
The axle nuts and the brake anchor
plate of back pedal brakes must be cor-
rectly fastened after each chain adjust-
ment process.
