SAFETY INSTRUCTIONS

The maximum load including cyclist and baggage is so kg.

Check the following before use

The rims are in good condition and undamaged. A worn rim is a safety risk and should be replaced.
Screw unions and components are properly tightened and not worn or damaged.
The seat is comfortably adjusted.
The brakes work properly.
The steering does not jam, or has too much play.
The wheels are not warped and the wheel bearings are correctly adjusted.
The wheels are properly attached in the back/front forks.
The tyres are in good condition and have the correct tyre pressure.
The pedals fit properly in the crank arms.
The gears are correctly adjusted.
All the reflectors are fitted.
After adjusting, check that all screw unions are correctly tightened and that the wires are undamaged and correctly drawn along the frame.
We recommend that you have the bike serviced every six months at a bike shop (more often if you ride it a lot or put a lot of strain on it). Fill in the service records after every service.

Road safety

Always wear a bike helmet.
Follow local traffic regulations.
Do not put anything on the bike that can get caught up and obstruct the functions of the bike.
Do not ride on the same side as oncoming traffic.
Do not ride alongside another bike. Do not give rides on bikes not intended for this.
Do not swing out into traffic.
Do not hang anything from the handlebars that makes it difficult to steer, or which could fasten in the front wheel.
Do not hang onto another vehicle.
Do not ride too close to a vehicle in front.
Cycling in the rain or on wet roads:

The braking power is reduced by water and ice.
Cycle more slowly in wet weather and brake earlier than in dry weather.

Follow local regulations when cycling in the dark:

The bike must have a front lamp with a white light and a back lamp with a red light, in addition to the reflectors already fitted on the bike.
Wear bright clothes and a highvisibility jacket if possible.
Check that the bike’s reflectors are correctly positioned, properly attached, clean and not obscured. Replace damaged reflectors immediately.

Any shock absorbers on the bike should be serviced at a bike shop. See instructions from shock absorber manufacturer.

Service

Only use identical spare parts when replacing parts that are essential for safety. Check Ju la’s department store for original parts. This will guarantee that the bike remains safe to use.

WARNING

A bike is exposed to wear, like all mechanical equipment, when you use it. Different materials and components react in different ways to wear and stress. If the lifespan of any part of the bike (including the frame, forks and components) has been exceeded there is a risk of the part suddenly breaking, and that you lose control and fall off. Cracks, scratching or changes in colour in areas exposed to high levels of stress indicate that the component has reached the end of its life and should be replaced. Never lift the handlebar post or saddle post over the marking for the top position.

NOTE:

All modifications are at your own risk.
It can be dangerous to use the bike for freestyle biking, stunt tricks, competitions, off-road biking etc., and you are personally responsible for any subsequent injuries or other damage resulting from the use of the bike in this way. The dealer waives all liability for any consequential damage or other loss in relation to the person who has purchased that bike or any third party. It is important to inform the child about the functions of the bike, especially the safe use of the brakes.

ASSEMBLY

Support wheels

Make sure the support wheels are adjusted to the right height. If the support wheels are placed too low this can interfere with the angle of the bike, and can also have a negative effect on the braking power if the back wheel lifts too high from the ground. Lift up the support wheels more and more as the child gets better at cycling to avoid these problems.

NOTE

The pedals are not the same – the pedal marked R should sit on the right-hand crank arm and the pedal marked Lon the left-hand crank arm.
Use a suitable lubricant on the pedal threads when fitting them.

FIG. 2

Fitting the right-hand pedal (R)

Screw in the pedal on the chain side crank arm, and carefully tighten with a spanner.

FIG. 3

Fitting the left-hand pedal (L)
Screw in the pedal (anticlockwise) on the opposite side of the chain, and carefully tighten with a spanner.

FIG. 4

It is important that the bike is both comfortable and safe to use. Follow the instructions to adjust the different parts of the bike.

SADDLE

Adjust the height of the saddle by releasing the clamping screw that holds the saddle post to the saddle tube. Set the saddle post to the required height and tighten the clamping screw.

FIG. 5 NOTE

The saddle post be lower than the marking for the top position. It should not be possible to see the marking for the top position.
Tighten the saddle post clamping screw and nut to 30 Nm. Use a 6 mm hex key or 13 mm hex spanner. Check that the saddle post is securely fastened by trying to turn the saddle by hand (it should not be possible to turn the saddle).

Saddle height

To find the correct saddle height, put one of the pedals in its lowest position. Sit on the saddle wearing shoes and check that the heel just reaches down to the pedal with the leg stretched out. When cycling with the sole of the foot on the pedal the leg should be slightly bent when the pedal is in its lowest position (see figure).

FIG. 6

HANDLEBAR POST

Release the expander screw on the lower part of the handlebar post until the expander key comes loose. Carefully tap the expander screw if the key does not come loose by itself. When the expander key has released, move the handlebar post up or down to a position which feels comfortable and where it is easy to reach the handlebars and brake levers, and then firmly tighten the expander screw. Check that the handlebar post is in line with the front wheel.

FIG. 7

NOTE

There is a marking on the handlebar post to show how much it can extend from the fork tube. This marking should not be seen when the handlebar post is fitted. The handlebar post must be inserted far enough into the fork tube so that the marking cannot be seen. When you have found the right height, position the handlebars at right angles to the front wheel. Firmly tighten the expander screw. It is very important that the expander screw is properly tightened. Check that the handlebar post is properly secured by standing in front of the bike with your legs on each side of the front wheel. Hold the wheel with your legs and try to turn the handlebars sideways. The handlebar post must not rotate in the fork tube. Do not overtighten the handlebar post. It should be able to give somewhat if you fall off the bike. Position the handlebar grips horizontally and firmly tighten the clamping screw.

Safe braking

Brake a bit sooner with the back brake that with the front brake.
Never brake with the front brake when turning. It is especially important to remember this on sharp curves or on rough or slippery surfaces.
The braking capacity is reduced on wet or slippery roads. Bike more slowly and brake earlier.
Do not ride the bike if the brakes are not working properly.

Rim brakes

Check the brake adjustment and lubricate the brake spring pivots regularly. Lubricate the exposed parts of the wires to provide protection from corrosion. If it is difficult to brake this can be because the wires are not properly lubricated. The brake wires must be removed to lubricate them.
Replace the brake pads before they are so worn that the pattern is worn off, or the wear indicator shows that it is time to replace them.

NOTE

In order to brake smoothly the wheels must not be buckled, they must be correctly adjusted and the sides of the rims must be smooth without any dints. The brake pads must be correctly adjusted to the sides of the rims. Protect the ends of the wires with end caps, so that the wires do not fray.
The brakes must not jam or remain pressed against the rims when they are not used. If the brakes jam, check that the brake caliper, wires and brake levers are clean and lubricated.

MAINTENANCE

TYRE MAINTENANCE AND WHEEL ADJUSTMENTS

The tyres must have the correct air pressure, indicated on the side of the tyre, if they are to function well and last a long time. Pump up the tyres with a foot pump or hand pump and a suitable valve connection, and check the pressure with a pressure gauge.
Locking the brakes and skidding wears out the tyres.
Avoid contact with oil, petrol, paraffin and other agents that dissolve rubber.
Check that the wheels are not buckled and are correctly aligned so that the sides of the tyres do not touch the frame, the front fork, or the front brake.
Check that the tyres are not worn or cracked. Make sure that the tread on the tyres has not worn down and that there is no damage, cracks or uneven wear on the tyre.
Replace worn or damaged tyres immediately.
Sharp stones or uneven surfaces can puncture the tyres.

RIMS

Most rims have a wear indicator in the form of a line along the side of the rim. The rim should be replaced when this line is completely or partially worn off. It is then worn out.

Lubrication

The chain should be lubricated regularly; use a suitable chain oil. Check that the chain does not knock when cycling, or is damaged. Always keep the chain oiled.
