4. Routine Maintenance Check and Lubrication
WARNING! As with all mechanical components, your bicycle is subjected
to wear and stress. Different materials and components may react to wear or
fatigue in different ways. If the design life of a component has been exceeded
it may suddenly fail, possibly causing injuries to the rider. Any types of cracks,
scratches, or change of coloring in highly stressed areas indicate that the life of
the component has been reached and it should be replaced immediately.
Always inspect your bicycle before every ride.
WARNING! Use only genuine replacement parts, particularly for safety-
critical components, installed by a professional bicycle mechanic. To keep your
electric bicycle functioning well, the following routine maintenance lubrication is
necessary (refer to Fig. 5):
Half-Yearly: Remove,
clean, and lubricate chain,
derailleur(s), cog set, and all
cables. Check and replace
as required.
Weekly (or as needed):
Wash bicycle with warm
soapy water. Dry with a
soft, nonabrasive cloth. Do
not use strong chemicals
or abrasives. Do not use
a high-pressure washer.
Inspect your bicycle while
cleaning.
WARNING! Every six months, your pedal electric assistance bicycle should be
professionally checked to ensure that it is in correct and safe working order. It
is the responsibility of the rider to ensure all parts are in working order prior to
riding.
