-there are may possibilities for changing your bike subsequently.

Working on bikes, including work which is assumed to be very simple, requires sound training, sound knowledge and a great deal of experience.

Unprofessional work on your bike can lead to dangerous riding situations, falling, accidents and material damage.

wear clothing with reflecting stripes and ride with the light on.

 Only carry your luggage on suit-

able carrier systems. These are bike panniers or luggage carriers approved by the manufacturer. Please consult your dealer.

 Loading increases braking distance.  Please note that many items of

clothing and/or use of a rucksack can restrict your freedom of movement.

ASSEMBLY AND FUNCTION KIDS BMX | EN | 11

 BMX bike: No StVZO specification, no gears,

optionally only one brake, foot pegs on front and rear wheels, handlebars rotatable through 360°

kidbmx

Your bike has  A derailleur gear, easily recognisable by a

sprocket set on the rear hub and a crank wheel set with several chain rings or

 a hub gear, recognisable by a “fat” rear hub or  no shifting system.

These gears provide you with the optimum gear for any speed and amongst other things make climbing inclines easier.

You can find out the number of gears as follows:  Derailleur gears: Multiply the number of crank

wheel sprockets at the front with the number of sprockets on the rear sprocket set. For example, 3 crank wheel sprockets x 9 rear sprockets = 27 gears.

 Hub gears: The number of gears is indicated

by the highest number of gears shown on the gear selector.

5Before using for the first

time

RISK OF PERSONAL INJURY AND MATERIAL DAMAGE!

An unroadworthy bike can lead to dangerous riding situations, fa lling, 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 particular check 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 a fa ll. 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 therefore your initially greater braking distances.

 Disc brakes need to be initially run

in. Full braking efficiency only develops after the running-in process. Please note the enclosed brake manufacturer‘s running-in instructions. A rule of thumb is: Ride 1 km with permanent razing brakes, following 2 hard 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 pedals.

 If after purchasing you remove

the saddle support and front and/ or rear wheel for transportation please follow the appropriate instructions in Chapter 10.1 and 10.2.

1. Have your dealer confirm proper final assembly and the roadworthiness of your bike.

2. Have your dealer adjust the correct saddle position.

You can make fine adjustments and minor changes yourself as described in Chapter 6.2.2 “Adjusting the saddle position”.

3. Only use this bike when your dealer has familiarised you with your bike’s technical features in a briefing.

4. Seal your bike with aerosol wax polish, see Chapter 11.

5. Before using read Chapter 6.

BEFORE EVERY TRIP KIDS BMX | EN | 13

6Before every trip

RISK OF PERSONAL INJURY AND MATERIAL DAMAGE!

An unroadworthy bike can lead to dangerous riding situations, fa lling, accidents and material damage

Also consider the possibility that your bike may have fallen over when unattended 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 later be able to recognise deviations from the correct condition (photos you take yourself can be a valuable aid).

 Contact your dealer immediately if

you discover that your bike‘s condition 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 material 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.

mtb009, wear indicator (arrow)

mtb010, wear indicator (arrow)

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 situations, falling, accidents and material damage.

Have the tyre seating corrected by a specialist workshop. You can undertake this job yourself if you are fa miliar 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.
