● 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.
● Check play on the hub axle (see image 37 ). Hub bearings can
develop play due to wear. Excessive hub play can affect brake
performance, it can cause other mechanical problems as well
as affect the handling of the bike. Contact your Urban Arrow
dealer in case you detect play on the hub axle.

● Check play on the steering linkage (see image 4 ): the steering
input of the handlebar needs to be transferred to the front
wheel. This action is provided for by the steering linkage. The
linkage consists of a vertical head tube 18 and a horizontal
head tube 38 . The steering column is connected to the
steering rod with hingeable pivot joint. The steering rod is
linked to the front fork with a ball joint.

A malfunctioning steering linkage during cycling may lead
to loss of control of the bike. This can potentially be fatal.
Always contact your Urban Arrow dealer in case the steering
linkage feels loose or encounters excessive resistance. Never
continue to ride the bike when there is no response from the
front wheel after you give steering input.
