Wheels can be fastened with a quick release
mounting and therefor they are susceptible to
theft. For this reason always lock the wheels
along with the frame to a solid object when
you park your bicycle somewhere.
Please pay attention to the instructions about
quick release levers on page 9.
Danger!
Check your tires for dam-
age on a regular basis. You should ex-
change tires with worn threads or dam-
aged sidewalls. Damaged rim tapes have to
be exchanged immediately. Damages at the
tires may lead to a sudden burst of the tire
and thus result in a serious fall and injury.
Repairing a flat tire
An unseated tire can rupture unexpectedly
and cause serious injury or death. Be sure the
tire is properly seated when inflating the tube.
To fix a flat tire start with removing wheel
from tricycle. Deflate tire completely.
Then squeeze the tire beads into the center
of the rim. Use a tricycle tire lever set to pry
the tire bead up and out of the rim. Start left
and right from the valve. Repeat around the
wheel until one bead is off the rim.
Then remove tube and, if you want to change
it, the tire.
Carefully inspect inside of the rim and tire for
the cause of the flat.
By inflating the tube a little bit it will be easier
to place it inside the tire.
Insert the valve stem through valve stem hole
in rim and fix it with the valve nut.
Start at the valve stem when installing the first
bead on the rim by pushing it over the rim
flange with the thumbs.
Repeat for the second bead. Take care that
the tube will not be damaged by tools or by
pinching between tire and rim.
Slowly inflate the tire, checking the tire is
seated properly and not pinched as the tire is
inflated.
Inflate the tire to the recommended pressure
(see tire sidewall).
Spokes
The spokes of the wheels connect the rim to
the hub. They transmit the braking power of
the disc brakes, and in addition they transmit
the pedal forces at the rear wheel.
Attention!
To true up the wheels
you need special skills, please have this
work done by an experienced bicycle me-
chanic.
Danger!
Take care that your spokes
are always in perfect condition and the
spoke tension is balanced. Do not ride
with wheels that run untrue or wheels
with loose or missing spokes. These faults
may lead to a total failure of the wheel
while braking and result in a serious fall!
Rims
The flanges of the rims wear out by braking
with rim brakes.

rims come with indicators
that show the condition of the flange.
As long as you can see the slot that is en-
graved on the flange where the brake pads get
in contact, the rims are fine.
As soon as you can not see the slot any more,
you must not ride the bike until you changed
the rims.
Please contact your special dealer for more
information.
