Wear
Warning
Excessive wear, material fatigue or loose screw connections can cause
functional impairments that may lead to accidents or falls.
Risk of accident and injury!
►
Regularly inspect the pedelec for wear.
► Do not use the pedelec if there are deformations, cracks and changes
in colour.
► Do not use the pedelec if there is excessive wear or loose screw con
-
nections.
►
If you discover any excessive wear, loose screw connections, cracks,
deformations or discolouration, have the pedelec inspected immediately
by a bicycle dealer.
Like all mechanical components, the pedelec is subject to wear and high loads. Different
materials react to wear or abrasion caused by stress in different ways. Any type of crack,
scratch or discolouration indicates that the useful life of the component is coming to an
end. Worn components must be replaced.
Only a bicycle dealer can assess the wear on components made from aluminium, carbon
or composite materials. Components made of composite materials are sensitive to high
temperatures (e.g. thermal radiation) and can be damaged as a result.
Heavy impacts, bumps and distortion are detrimental to frames, forks and wheels made
of carbon and composite materials. This has a detrimental effect on the internal structure
of the material without this being outwardly visible.
→ Ask a bicycle dealer for advice about the wear components on your pedelec.
→
Check the condition of all wear parts at regular intervals.
→
Maintain wear parts regularly.
