5Before using for the first
time
RISK OF PERSONAL INJURY AND
MATERIAL DAMAGE!
An unroadworthy bike can lead to dan-
gerous riding situations, falling, accidents
and material damage This same danger
exists if you are not yet familiar with
your new bike and its controls.
Familiarise yourself with this bicycle
before you first ride it. In particu-
larcheck with brake lever operates
the front brake and which the rear –
see Section 7.7.
Modern brakes have a very power-
ful braking effect. Excessively strong
operation of the brake levers can
cause the respective wheel to lock
and can therefore lead to afall.
Familiarise yourself slowly with the
braking effect on your bike in a safe
area of land.
With new rim brakes and after re-
placing brake blocks the full braking
effect only develops after a certain
run-in period. Please note there-
fore your initially greater braking
distances.
Disc brakes need to be initially run
in. Full braking efficiency only de-
velops after the running-in process.
Please note the enclosed brake
manufacturer‘s running-in instruc-
tions.
A rule of thumb is: Ride 1 km with
permanent razing brakes, following
2hard braking procedures from a
speed of approximately 30 KPH ( ...
19 miles per hour)
If your bike is fitted with optional
click-in pedals which firmly connect
the shoe with the pedal:
Practice using them by mounting and
dismounting.
Click-in pedals are not safety ped-
als.
If after purchasing you remove
the saddle support and front and/

RISK OF PERSONAL INJURY AND
MATERIAL DAMAGE!
An unroadworthy bike can lead to dan-
gerous riding situations, falling, accidents
and material damage
Also consider the possibility that your
bike may have fallen over when unat-
tended or that someone might have
tampered with it.
Check that your bike is roadworthy
before every trip.
Memorise your bike‘s correct condi-
tion when new so that you will lat-
er be able to recognise deviations
from the correct condition (photos
you take yourself can be a valu-
able aid).
Contact your dealer immediately if
you discover that your bike‘s condi-
tion is different from normal.
Only ride the bike again after it has
been properly readjusted by the
dealer.
1. Visually inspect the whole bike:
Check all fixing screws for correct
tightness (see Chapter 1.2.4)
Check the entire bike for dents, ruptures,
deep scratches and other forms of
mechanical damage.
Contact your dealer if visual inspections shows
defects of any description.
6.1 Check the wheels
Front and rear wheels are both called
wheels.
A wheel consists of
the hub,
On the rear wheel hub only Sprocket or
sprocket cassette,
Brake disk, if fitted,
Spokes
Rim and the
Tyre equipment, which in turn consists of
—Tyre casings,
—Tube and
—Rim tape insert.
Many bikes are fitted with tubeless tyre road
wheels. On these tyres with no tube are fitted on
special rims. A tube can also be fitted however.
On StVZO-equipped bikes rim reflectors may be
fitted.
6.1.1 Check fitting
1. Shake both wheels at right angles to the
direction of travel.
The wheels must not move in the forks.
There must be no audible creaking or
rattling sounds.
Contact your dealer if this check shows defects of
any description.
6.1.2 Check the rims
RISK OF PERSONAL INJURY AND
MATERIAL DAMAGE!
Worn rims and/or substantial warping or
run-outs may lead to hazardous riding
situations, falling, accidents and mate-
rial damage.
Worn rims must be replaced and warping
or run-outs repaired!
RISK OF PERSONAL INJURY AND
MATERIAL DAMAGE!
With rim brakes: Dirty rims may reduce
braking efficiency.
Dirty rims must be cleaned immediately.

1. Check rims for wear:
Rims with wear indicators:
Visual check
Rims without wear indicators:
Visual check
Fingernail check: Run your fingernail
across the rim shoulder. No scoring
should be felt.
If the wear indicator is no longer visible or
if the rim has discernible scoring the rim
must be replaced.
2. Check rims for run-out:
Lift the bike up and spin first the front and
then the rear wheel.
Note the distance between the rim and
the brake shoes and on disk brakes the
distance between the rim and the frame
strut or fork leg.
Maximum permissible deviation per
revolution is 2 mm.
3. Check your rims for dirt, especially oil and
grease.
Dirty rims must be cleaned immediately (see
Chapter 11)
6.1.3 Check tyres
1. Check the valve position:
Does not apply to tubeless tyres.
RISK OF PERSONAL INJURY AND
MATERIAL DAMAGE!
In the event of angled valve the base of
the valve can rip off when riding which
causes sudden loss of tyre pressure.
This can lead to hazardous riding situ-
ations, falling, accidents and material
damage.
Have the tyre seating corrected by a
specialist workshop.
You can undertake this job yourself if
you are familiar with fitting and removing
the road wheels (see Chapter 10.1) and
replacing the tyre and tube.
Remove the valve nut.
Check the valve position:
The valves must point directly towards the
centre axis of the wheel.
mtb012, valve pointing directly towardsroad wheel
axis

BEFORE EVERY TRIP KIDS BMX |EN |15
mtb011, valve not pointing directly to wheel axis
2. Check the tyre pressure:
Determine your tyre type
Mountain bikes can be fitted with rac-
ing bike type tyres and racing bikes with
trekking tyres.
Rule of thumb:
Mountain bike tyres: Tyre width greater
than 40 mm
Trekking / Cross-country and Fitness bike
tires: Tyre width from 28 mm – 40 mm
Racing bike style tyres: Tyre width less
than 28 mm
Consult your dealer to determine your
tyre type.
Pressures:
Mountain bike tyres: 2.0 – 3.5 bar
Trekking bike tyres: 3.5 – 5.0 bar
Racing bike tyres 6.0 – 10.0 bar
RISK OF PERSONAL INJURY AND
MATERIAL DAMAGE!
Too low a tyre pressure leads to in-
creased likelihood of punctures but
mostly dangerous handling. The tyre can
come off the rim on bends and cause
wandering of the tyre on the rim. This
can lead to hazardous riding situations,
falling, accidents and material damage.
Inflate your tyres to the correct pres-
sure.
Many tyre pressures are given in “psi”.
Convert the pressure using the follow-
ing table.
psi 30 40 50 60 70 80 90 100 110 120 130 140
bar 2,1 2,8 3,5 4,1 4,8 5,5 6,2 6,9 7,6 8,3 9,0 9,7
The actual permissible tyre pressure can be found
in the tyre and rim manufacturer’s instructions. The
permissible tyre pressure is mostly embossed on
the tyre wall. Please consult your dealer.
The higher your body weight the higher
the tyre pressure needs to be.
Check the tyre pressure with a tyre pressure
gauge. Simple gauges are often included with bicy-
cle tubes and higher quality gauges are available
from your dealer. How to use them is either in the
instructions for used or you can have your dealer
demonstrate this.
If pressure is too low: Increase the pressure by in-
flating with a suitable pump.
If pressure is too high: Release sufficient air via
the valve and check the pressure again afterwards
with a gauge.
Using a bicycle pump with a pres-
sure gauge you can check the pressure
whilst inflating the tyre. Let some air out
of the tyre first and then increase the
pressure to the desired level.
There are various types of valve. All
valves can be fitted with a dust cap.
After removing the cap you can place
the pump head directly on the valve in
the case of either a Schrader valve or
the so-calledPresta valve. On a racing
bike valve you must first screw the little
locking screw out of the valve until the
stop and tighten it again after inflat-
ing the tyre. Get your dealer to demon-
strate operation of the valves to you.

3. Checking your tyres for external damage and
wear:
The tyre rubber must have the same
pattern as the original over its entire
surface.
The tyre canvas beneath the layer of
rubber must not be visible.
There must be no bulges or tears.
4. Checking the fit of your tyres:
Lift the front or rear wheel and turn it
by hand.

There must be no highs or lows.
6.1.4 Other checks
1. Check your road wheels for loose items such
as, for example, pieces of branches, residues,
loose spoke reflectors etc.
Remove these if this is possible without
applying any great force.
Check if your wheels have been damaged
by these loose items.
Tighten loose bicycle parts such as
spoke reflectors, for example. If you find
this is not possible contact your dealer
immediately.
Please note that all reflectors are
present as per StVZO (see Chapter 2.1.4),
correctly secured and not obscured or
dirty.
6.2 Check saddle and seat post
RISK OF PERSONAL INJURY AND
MATERIAL DAMAGE!
If the seat post is not inserted far
enough the seat post can come loose.
This can lead to hazardous riding situ-
ations, falling, accidents and material
damage.
Note the correct seat post insertion dis-
tance. Please read Chapter 7.3 for in-
formation.
If you have the correct technical knowl-
edge you can tighten this yourself.
Please read Chapters 7.2, 7.3 and 10.2 for
information.
