Safety
After an accident
on page 30, and “Wheels” on page 24
of this manual.
Check that handlebars and stem are nei-
ther bent nor broken and that they are
level and upright. Make sure the stem
is firmly fixed on the fork by trying to
turn the handlebars relative to the front
wheel. Briefly lean on the brake levers
to make sure the handlebars are firmly
fixed in the stem.
Realign the components, if necessary,
and carefully tighten the bolts to ensure reli-
able clamping of the components. The max-
imum torque values are printed directly on
the components or specified in the enclosed
operating instructions.
For more information see the section
discussing “Fit” on page 18, especially
“Handlebar height and angle” on page 21.
Check whether the chain still runs on the
chainrings and the sprockets. If your bike
fell over to the chain side, check that the
gears function properly. Ask somebody
to lift the bike by the saddle and carefully
shift through all the gears. Pay particular
attention when shifting to the small gears
and make sure the rear derailleur does
not get too close to the spokes as the
chain climbs onto the larger sprockets.
If the rear derailleur or the dropouts/
derailleur hanger are bent, the rear derail-
leur may collide with the spokes. This can
result in damage to the rear derailleur, the
rear wheel and the frame. Check the func
-
tion of the front derailleur, as a displaced
front derailleur can throw off the chain, thus
suddenly interrupting the drive of the bike.
For more information, see”Shifting gears”
on page 33.
Make sure the saddle is not out of align-
ment, using the top tube or the bottom
bracket shell as a reference. If necessary,
open the clamp, realign the saddle and
re-tighten the clamp.
For more information, see “Seatpost cam
action clamp” on page 29 and “Saddle
position” on page 19.
Let your bike bounce on the ground from
a low height. If there is any rattling, see
where it comes from. Check the bear
-
ings, the bolts and the proper seating
of the battery and the connectors, as
necessary.
Check the display. Are all the values dis-
played as usual? Do not use your bike if
the display shows an error message or
a warning. If necessary, switch off the
system and wait at least 10 seconds
before checking it again.
Do not set off on your bike with drive
assistance if the control element shows a
warning. In such a case contact your bicy
-
cle dealer immediately.
You can find further information in the
corresponding chapter of the system man-
ual of the drive manufacturer.
Finally, take a good look at the whole
bike to detect any deformation, color
changes or cracks. Ride back very care-
fully by taking the shortest route possible,
only if your bike went through this check
without any problems. Do not acceler
-
ate or brake hard and do not ride your
bicycle out of the saddle. If you are in
doubt about the performance of your
bike, have yourself picked up by car,
instead of taking any risks.
