● Check tyres for wear and damage: A worn tyre can be
recognized by checking the tread pattern. If the pattern has
disappeared in the middle of the tread (difference between
lowered and raised material cannot be distinguished) the tyre
is worn and should be replaced (see image 33). If you notice
long or deep tears the tyre should be replaced even if the
tread hasn't worn out yet. Contact your Urban Arrow dealer
for the correct spare part.

● Check tyre pressure: Riding a too low tyre pressure damages
the tyre. In the sidewalls tears will appear that cannot be
repaired. Sometimes a few hundred km's at too low pressure
is enough to ruin the tyres. The correct tyre pressure is as
follows:
a. Front wheel: 2.4-3.5 bar
b. Rear wheel: 3-4 bar

● Wheel trueness : If a wheel is out of true it will wobble while
spinning. You can check this by putting the bike on its stand
and giving the wheels a spin (see image 34). If the wheel is
spinning look at the rim and tyre separately. An incorrectly
fi tted tyre can also cause a wobble. A new wheel needs to
settle and will require its trueness being checked more often.
Contact your Urban Arrow dealer in case your wheel wobbles
to have your wheel fi xed.

● Check the rim for damage. Damage can take the form of dents
and cracks in the rim surfaces and around the spoke holes.
Always check the rim after hitting a solid object or pothole
at speed or after you rode with a fl at tyre. A damaged rim
may damage the tyre and could make the wheel go out of
true. Contact your Urban Arrow dealer in case you detect rim
damage.
