Checking The Spokes; Checking The Tyres; Incorrect Tyre Pressure Reduces Cycling Comfort And In The Worst - Cube CARGO HYBRID 2020 Originalbetriebsanleitung

6.2.3 Checking the spokes

Check the spokes on the front and rear wheel
1.
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.
Check the tyres of your Cargo Hybrid
Î
regularly as described here.
Only carry out the work on the tyres
Î
mentioned here yourself if you have
the necessary expertise.
If you do not have the necessary
Î
expertise for certain work or are unsure,
contact your bicycle dealer.
Check the valve position.
1.
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.
Check the air pressure.
2.
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.
psi 30 40
bar 2.1 2.8
psi
90 100
bar
6.2 6.9
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.
If necessary: Correct the air pressure, taking
3.
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.
