CARGO HYBRID
6.2.3 Checking the spokes
1.
Check
the spokes on the front and rear wheel
regularly.
All spokes must be tight and undamaged.
Even individual spokes that have become
loose or damaged can cause consequential
damage.
Do not
use
your Cargo Hybrid if spokes
have become
loose
or
damaged
or if
spokes are missing
!
2. Consult your bicycle dealer if spokes have
become loose or damaged.
6.2.4 Checking the tyres
WARNING!
Risk of a burst tyre or sudden
loss of pressure!
If the valves are tilted, the valve foot
can break off while cycling, which
causes a sudden loss of pressure
in the tyre.
Incorrect tyre pressure reduces
cycling comfort and in the worst
case the tyre can burst at full speed.
Î
Check the tyres of your Cargo Hybrid
regularly as described here.
Î
Only carry out the work on the tyres
mentioned here yourself if you have
the necessary expertise.
Î
If you do not have the necessary
expertise for certain work or are unsure,
contact your bicycle dealer.
1.
Check
the
valve position
.
The valves must point towards the centre
of the wheel. Tear off diagonally positioned
valves while cycling, so that there is a sudden
loss of pressure in the tyre (= the air escapes
abruptly, high risk of accident/fall).
Correct inclined valves if necessary if you
have the necessary expertise or consult your
specialist bicycle dealer.
2.
Check
the
air pressure
.
The
optimum air pressure
depends on
the
type of tyre
with which your Cargo
Hybrid is equipped.
As a rule, you will find an indication of
the
maximum permissible air pressure
directly on the
rims
(sticker) and
tyres
(tyre pressure).
If you are unsure, ask your specialist
bicycle dealer.
Some air pressure values are given in “psi.”
You can use the following table to convert
the values.

The higher the body weight, the higher
the tyre pressure must be.
• Check the air pressure with a tyre pressure
gauge. Simple devices are often accompa-
nied by bicycle inner tubes, high-quality
devices are available in specialist shops.
• Observe the relevant operating instructions
for handling the tyre pressure gauge or
have your specialist bicycle dealer show
you how to use it.
3. If necessary:
Correct
the
air pressure
, taking
into account the maximum permissible air
pressure for rims and tyres.
• Excessively
low air pressure
: Increase the
air pressure with a suitable pump.
• Excessively
high air pressure
: Release an
appropriate amount of air through the
valve and then check the air pressure again.
• Using a
bicycle pump with pressure
gauge
, you can check the air pressure
while inflating: First let some air out of the
tyre and then increase the air pressure to
the desired level.
