Ensure you very carefully check the carbon
frame for damage after a fall or an accident
involving your carbon FLYER. If you are not ab-
solutely certain that the frame is undamaged,
please have the bike checked by a specialist.

28.3 Visual checks
28.4 Carbon frame
Transition area of the threaded bushing of
the drink holder, slot of the dropouts, bearing
areas in full-suspension frame, suspension
mounting elements on the main frame and
rear suspension, seat clamp, derailleur hang-
er, derailleur clamp area, disc brake mounting
or brake boss, press-fit area of the headset as
well as the threads of the bottom bracket cups.
The torque for securely
fastening carbon com-
ponents on the carbon
frame can be lower than metal compo-
nents. If the torques are too high, this
can lead to hidden damage which can-
not be identified from the outside. It can
cause the frame to break or change,
which could in turn cause falls. You
therefore always have to adhere to the
enclosed information from the manu-
facturer or ask a specialist. Always use
a torque spanner to fit parts with the
correct torque.
28. Carbon components
As a special material, carbon (carbon fibre)
requires special handling and care. This
applies for the design of the pedelec, the
maintenance, the riding style as well as the
transport and storage.
28.1 Properties
Carbon parts may not be bent,
dented or misshapen after an
accident or fall. Fibres could
be destroyed in some cases or have
loosened without being visible from the
outside. Carbon parts can already
be damaged from past falls.
These parts could suddenly
fail and trigger serious accidents.
That is why carbon add-on parts as
well as carbon frames should be thor-
oughly inspected at regular intervals.
• Check if individual layers such as
paint, finish or fibres, come off.
• Look for changes to the carbon sur-
face or splintering, deep scratches
and holes.
• Check if the components feel less se-
cure or stiff than usual.
If you believe that one or more compo-
nents are not in perfect working order,
these should be replaced immediately
before the pedelec is used again.
The following components are areas
which should be regularly checked (at
least every 100 km) for irregularities
such as cracks, breaks or changes to
the surface, as well as after a fall or ac-
cident:
