15. Brake
1. Brakes are safety components. Have
the setting and maintenance work per-
formed by your FLYER specialist retail-
er. 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,
traffic-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 condi-
tions such as on sand or a smooth
surface. You should then exercise
great care, slowing yourself down us-
ing 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 give the brakes sufficient
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 your-
self with the brakes, practising using
them and practise emergency brak-
ing, starting on safe ground with no
traffic before setting out into the traf-
fic. Look ahead while riding. Only use
original replacement parts. Otherwise
it is possible that the functionality of
your FLYER e-bike may be impacted
or damaged. Adjust the brake lever to
ensure that it does not touch the han-
dlebars when pulled hard.
Only original spare parts may be used
when changing the brakes.
Disc brake
Disc brakes must be installed and ser-
viced by a FLYER specialist retailer. In-
correctly set up brakes can cause acci-
dents and serious injuries.
A brake test is required before each drive and
particularly after each brake adjustment. Braking
behaviour may vary, in particular after exchanging
the brake pads. Disc brakes require a bedding-
in time to wear in the discs and pads. The brake
does not deliver its full braking performance until
after around 10 heavy braking operations under-
taken at 30 km/h. The braking force increases
during this time. Consider this during the entire
duration of the wearing-in period.
This wearing-in period is also required after re-
placing the brake pads or discs.
Pay attention to any unusual noise when brak-
ing, as this could be a sign that the brake pads
have worn down to the wear limit. Check the
thickness of the brake pads once the brakes have
cooled down. If necessary, have the brake pads
replaced.
Please do not touch the brake disc while
it is rotating. You can suffer serious inju-
ries if your finger is caught in the gaps of
a rotating disc brake. The brake calliper
and disc may get hot during braking. You
could suffer burns if you touch this part
during or directly after braking.
