Tyres And Inner Tubes; Dealing With A Flat Tyre - Flyer C SERIE Originalbetriebsanleitung

12.2 Tyres and inner tubes

Tyres, like many other parts, are subject
to wear and tear. Check the profile
depth, tyre pressure and state of the lat-
eral tyre surfaces at regular intervals
and take note of signs of brittleness or
wear.
Do not exceed the maximum tyre pres-
sure recommended when inflating the
tyres. Otherwise this could lead to a tyre
exploding.
The tyres must be pumped up with at
least the stated minimum tyre pressure.
The tyre might detach from the rim if the
tyre pressure is too low.
The values for the permitted maximum
and minimum pressure are imprinted on
the lateral tyre surface.
Tyres may only be changed for identi-
cal, original tyres. The bicycle's handling
could otherwise be negatively affected.
This may lead to accidents.
You should only replace damaged parts
with original spare parts.
Most FLYERS use car-type
valves or Schrader valves. This
valve type allows you to top
up the tyre pressure of your
FLYER
stations. Specialist retailers will
let you know which type of air
pump fits your car-type valves.
Tubes may only be changed for
identical, original tubes.

12.3 Dealing with a flat tyre

Correct and safe repair of a flat tyre requires
specialised e-bike knowledge and special tools.
Have technical defects and flat tyres exclusively
repaired by your FLYER specialist retailer.
Repairing a tire puncture involves having
to adjust safety-relevant components.
Incorrect mounting of the wheels and
brakes can lead to severe falls and inju-
ries. We strongly advise you not to repair
a tire puncture alone. Ask your FLYER
retailer to fix the tire puncture for you.

Get thorough instructions from your
FLYER specialist dealer and practise
changing the wheels and tyres under
their supervision if you plan to repair
your own flat tyres. The system must be
switched off and the battery must be re-
moved before changing a tyre or wheel.
You need the following equipment to repair a tire
puncture:
• Plastic tire lever
• Patches
• Rubber cement
• Sandpaper
• Open-ended spanner or wrench (for wheels
without quick release skewers)
• Air pump
• Spare tube
If your FLYER is equipped with a rim brake as a
V-brake, proceed to open the brakes as follows:
• Hold the wheel with one hand.
• Press the brake arms together against the rim
• Hang the bowden cable of the brake or the out-
er sheath of the bowden cable over one of the
brake arms
When removing the front and rear wheel,
make sure the pull cable is loosened.
If your bike is equipped with hydraulic rim
brakes, proceed to remove the brakes as follows:
• If you have quick releases for the brakes, you
can demount a brake unit according as in-
structed in manufacturer's instructions. (See
also p. 156)
• If you do not have a brake quick release, de-
flate all of the air out of the tyre.
If your FLYER is equipped with a disc brake, you
can remove the wheel without further preparation.
Please note: when fitting the wheel, the disk must
be slotted between the brake linings of the brake
calliper and ultimately be centred without contact.
In the case of back pedal brakes, the screws
on the brake arm of the chain stay have to be
opened.
2. Removing the Wheel
• If your bicycle has quick-release levers or ax-
les, open them.
• If your bicycle has hexagonal bolts, then loos-
en them in anti-clockwise direction with a fitting
ring spanner or box-end wrench.
