11. Bicycle weight
Information
If you want to know the precise weight of your bicycle,
we recommend having it weighed by your specialist
workshop. Most bicycle dealers have a professional and
accurate cycle weighing scale.
Pedelec: The maximum weight of your Pedelec
is given on the type plate  10.4 Pedelec: type plate
Page EN-16.
12. Permissible total weight
Warning
Serious falls and accidents caused by component
failure.
▪ Do not exceed the total permissible weight of the
bicycle, as this can lead to the breakage or failure
of important safety components. In addition, the
braking system is only designed for the permitted
total weight of the bicycle.
Total weight = weight of the bicycle + weight of the
rider + weight of the trailer + weight of the child
seat + weight of luggage and/or child.

13. Tightening torques for threaded
connections
Warnings
Serious falls and accidents caused by detached
or broken components.
▪ Have all assembly and adjustment work done in a
specialist workshop. If you must attach anything
yourself, use an appropriate
torque wrench and be sure to
comply with the specied
tightening torques.
Insuciently tightened
screws/nuts can loosen, tear
o or break. Excessively
tightened screws/nuts can
damage the components. The
tightening torques are
marked on the components
and in the operating
instructions. Tightening
torques provided by a
component manufacturer shall take precedence over
torque values given in these operating instructions
 5. Component guides Page EN-10.
▪ Observe the minimum screw-in depth. For hard
aluminium alloys, this is at least 1.4 times the
diameter of the screw.
▪ Carbon: Some carbon components require lower
tightening torques than metal components for secure
fastening. Excessive torques can lead to hidden
damage which may not be visible from the outside.
▪ Carbon: Carbon parts must be assembled using
a special assembly paste. You should also note
any other, diering information or markings for
recommended torques for carbon components.
