SAFETY INSTRUCTIONS
IMPORTANT:
The maximum load including cyclist and baggage is 120 kg.
OWNER’S RESPONSIBILITY
The instructions describe how to ride safe and keep the bike in good
condition. Read the instructions carefully, and follow them.
All the important servicing and adjustments to the bike should be carried out
at a bike shop. Follow these instructions if you do not
have access to a bike shop or want to do the adjustments yourself.
- Familiarize yourself with the components and accessories on the bike so that you can use them properly.
- 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 span 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 color in areas exposed to high levels of stress indicate that the component has reached the end of its useful life and should be replaced.
- 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 retailer 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 understand how the brakes work on the bike. If you do not use the brakes properly you could loose control of the bike and seriously injure yourself.
- Different bikes can behave in different ways when you brake, so it is important to learn how the bike behaves in different situations and how hard you should press the brake levers.
ALWAYS CHECK BEFORE USE
- That the rims are in good condition and undamaged. A worn rim is a safety risk and should be replaced.
- That screw unions and components are proper ly tightened and not worn or damaged.
- That the seat is comfortably adjusted.
- That the brakes are wor king proper ly. That the steering does not jam, or has too much play.
- That the wheels are not buckled and that the wheel bearings are correctly adjusted.
- That the wheels are properly attached in the back/front forks.
- That the tyres are in good cond ition and have the correct tyre pressure.
- That the pedals fit properly in the crank arms.
- That the gears are correctly adjusted.
- That all the reflectors are fitted.
- That all the screw unions are correctly tightened and that the wires are undamaged and correctly drawn along the frame.
- That all the nuts and bolts are properly tightened.
- That the rim/disc brake pads are not worn out.
- That the tyres are not worn or damaged.
- That the lights are working at the front and back.
- That all the reflectors are intact and clean.
- That the brakes are working properly.
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 high visibility 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. By law a bike must always be fitted with brakes and a bell. On public roads it is important to take the following into consideration:
-
As a road user you are obliged to be familiar with and to follow traffic regulations.
We recommend that you always wear a helmet when cycling. If you are under 15 and ride a two-wheeled bike you must by law wear a bike helmet. -
Never leave a child on the bike.
SERVICE
Only use identical spare parts when replacing parts that are essential for
safety. This will guarantee that the bike remains safe to use. 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). After adjusting, check that
all screw unions are correctly tightened and that the wires are undamaged and
correctly drawn along the frame.

Make sure the brake wire and gear wire are put on the right side of the front
fork. If the wires are not properly positioned the handlebars or fork has
turned, and must be turned back before fitting the handlebars.
- Grease the hole on the front fork and the expander bolt at the foot of the handlebars.
- Position the handlebars at the required height in the hole on the front fork, but sufficiently deep to be safe.
- Make sure the handlebars are straight and tighten the clamping screw with a 6 mm hex key.
FRONT WHEEL
-
Press the front brake together and unhook the brake wire so that the brake separates.
FIG. 2 -
Hook the front wheel in the front fork, with the tyre in the correct direction of rotation.
-
Make sure that the front wheel is centred between the fork legs and tighten the nuts alternately.
-
Press the front brake together and refit the brake wire.
FIG. 3
SADDLE AND SADDLE POST
Grease the saddle post and insert it into the saddle tube, and then lock to
the required height with the quick-release.
IMPORTANT:
The marking for the top position on the saddle post should not be seen over
the saddle tube.
PEDALS
The pedals are different and are therefore marked with “L” (Left) and “R”
(Right). If they are fitted on the wrong side or screwed in skew in the crank
arms this can damage the threads. Grease the threads on the pedals before
fitting.
FIG. 4
Fitting the right-hand pedal (R)
Screw in the pedal clockwise on the chain side of the crank arm and tighten
with a 15 mm combination spanner.
FIG. 5
Fitting the left-hand pedal {L)
Screw in the pedal anticlockwise, on the opposite side of the chain, and
tighten with a 15 mm combination spanner.
FIG. 6
USE
SITTING POSITION
It is important that the bike is correctly adjusted, so that it is both
comfortable and safe.
FIG. 7
Adjusting the saddle
FIG. 8
Height
Open quick-release on the saddle tube, move the saddle post to the required
height, and close the quick-release.
IMPORTANT:
The marking for the top position on the saddle post should not be seen over
the saddle tube.
Position over the pedals
Put the sole of one foot on the pedal with the crank arms horizontal. Undo the
nut holding the saddle to the saddle post. Adjust the position of the saddle
forwards or backwards until the pedal is directly under the knee. Very small
adjustments to the position of the saddle can affect both performance and
comfort. Move the saddle a bit at a time to find the best position. The saddle
can also be angled to the required position. A horizontal saddle is often
recommended.
GEARS
The bike has three hub gears and a shift lever on the right side of handlebars
to indicate which gear is engaged, 1, 2 or 3.
BRAKES
The bike has a hub brake at the back, which is engaged by pedaling backwards,
and a rim brake at the front for which there is a brake handle on the left
side of the handlebars.
Do not ride the bike if the brakes are not working properly.
Safe braking
Brake a bit sooner with the back brake than with the front brake and never
brake with the front brake when turning or on loose or slippery surfaces.
MAINTENANCE
GENERAL
Clean the bike regularly for best lifespan and functionality. Use a mild
detergent and avoid degreasing agents that can penetrate the bearings and
chain and interfere with the lubrication. Store the bike in a dry place,
protected from direct sunlight.
CHAIN
Lubrication
The chain should be lubricated at regular intervals. A dry chain wears more
quickly, is heavy going, and can rust.
- Lubricate the chain with a suitable chain oil.
- Pedal a few turns so that the oil gets into the links.
- Wipe the chain.
Adjusting
An incorrectly tensioned chain can be dangerous. If the chain can be moved
more than 1 cm up or down it must be tensioned. The chain must not be over
tensioned, there should be a little play.
- Undo the nuts on the back axle a little and pull the back wheel backwards to stretch the chain.
- Make sure that the wheel is straight, then firmly tighten the nuts.
- Check that the chain in correctly tensioned and that the wheel is firmly in place.
BRAKES (FRONT)
Adjusting the brake handle
Full braking power should be achieved when the handle is pressed in ha
away. The brake must not press against the rim when the handle is not pressed.
It should not be possible to press the handle all the way to the handlebars.
Increase or reduce the play by turning the adjusting sleeve on the brake
handle. If a larger adjustment is needed, release the wire lock on the brake
arm, move
the wire to the required position and firmly tighten.
FIG. 9
Adjusting the spring tension
The spring tension counteracts the brake touching the rim when the brake
handle is released. Turn the adjusting screws on each side with a suitable
Phillips screwdriver unti the arms move in parallel.
FIG. 10
Adjusting the brake pads
It is important that the brake pads press against the middle of the rim and do
not touch the tyre or go below the bottom edge. Undo the hex screw that holds
the brake pad and adjust the position of the pad when necessary. Pads that are
still not worn out do age and lose their capacity. Replace the pads when
necessary.
FIG. 11
Repairs
To replace brake pads and brake wires, contact your nearest bike shop.
GEARS
Adjusting
- Engage second gear by turning the gear lever on the right-hand side of the handlebars.
- Turn the adjusting screw on the derailleur on the right side of the back hub so that the yellow mar ker in the window is between the two wh ite lines and tighten the lock nut.
FIG. 12
TYRES AND RIMS
- Regularly check that the spokes are correct ly tensioned and that the wheels are not buckled or out of round.
- Check the wear line on the side of the rim that indicates the amount of wear from the brakes. Replace r the rim if the wear line can no longe be seen.
- Check the tyre pressures at regular intervals. The recommended tyre pressure is given on the side of the tyre.
- Check at regular intervals that the tyres are not worn or cracked.
- Avoid contact with oi l, petrol, paraffin and other agents that dissolve rubber.
HANDLEBAR POST
- Handlebars
- Hex key, 6 mm
- Expander screw
FIG. 13
Adjusting
Release the expander screw on the top edge of the handlebar post until the
expander key comes loose. Carefully tap the expander screw if the key does not
come loose by itself. Move the handlebar post up or down to a position where
you are sitting comfortably and can easily reach the handlebars and brake
levers. As a rule the handlebars should be at the same height, or slightly
lower, than the saddle. Check that the handlebar post is in line with the
front wheel.
IMPORTANT:
- The marking for the top position on the handlebar post should not be seen over the fork tube.
- It is very important that the expander screw is properly tightened. The handlebar post must not rotate in the fork tube.
