CHANGING A PUNCTURED INNER TUBE
You might eventually experience a
sudden or slow loss of air pressure from
a wheel. It may come from rolling over
sharp objects such as broken glass,
thorns, etc. or hitting an obstacle with
insufficient air pressure. In both cases, the
inner tube has been punctured and will
need to be fixed or replaced.
It is normal for a wheel to lose air
pressure after some time. You may
notice after a long period of storage
that the tires are almost completely
at. That doesn’t mean you need to
change the inner tube. Re-inate
your tire to the recommended tire
pressure from time to time to avoid
puncture.
We strongly recommend replacing
a punctured inner tube by a new
one instead of attempting to patch
repair an old tube. The reason is
that a tube repair is often weak,
and air can often leak from a
repaired tube. A new tube is a time
saving, rather cheap and safe
solution. Don’t worry, your old tube
will get recycled if you leave it at a
bike shop. Alternatively, it is also
possible to use it as an attachment
strap.
For a front wheel at or tire
replacement on a model equipped
with an electrical power assistance
system, the front wheel will have to
be removed with the motor. Only a
Trivel-trained person is qualied to
perform this work without causing
damages. It is thus strongly
recommended that the owner
contact an authorized Trivel
representative to have the work
performed. Should this not be done,
the owner shall not hold the
company liable for any damages
caused by an improper procedure
by a person who is unqualied and
not authorized by Trivel.
