Foreword

Mobiky bikes are designed to be used mainly on roads and cycle paths. They are not built for use on rough terrain. Using them in a manner for which they were not designed may lead to damage to the frame and the tyres.

SECURITY

Before first use:
Mobiky bikes are designed and built for cyclists between 1.20m and 1.95m tall and for a combined weight (cyclist + bike + luggage) of no more than 105 Kg.

When using the bike, take care to respect the rules of the Highway Code:

• Helmets recommended (their use reduces the severity of head injuries by 80%).
• Abide by the flow of traffic and road signs.
• Front and back lighting is obligatory as of nightfall.

 

Mobiky bikes must only be used on roads and cycle tracks. Any other use than that of a town bike is strictly prohibited (mountain biking, freestyling, riding down steps …)

Before each use:
The height of the saddle and the handlebars should be adjusted to suit you. To obtain the optimum position for pedalling, adjust the height of the seat so that, with a straightened leg, your heel rests on the pedal (in the lowest position).

Very important

When your Mobiky bike is unfolded (ready to ride):

• The seat stay must be completely supported by the rear fork.
• The handlebar and saddle must be secured tightly.
• Make sure the breaks are working correctly and check the tyre pressure.

 

Do not use your Mobiky if any of the above conditions are not met. If you have any doubts, do not hesitate to contact us or your retailer.

MAINTENANCE

Your MOBIKY bike requires a minimum of maintenance and regular servicing.
The frequency of this will depend on the regularity of conditions of use.

1. Cleaning:
   Your bike can be cleaned using a water jet, soapy water and a sponge. Do not use a high pressure washer and even less so, a steam cleaner. Grease may become liquefied inside the mechanical parts, the bearings and the gears would soon seize up which would immobilize your bike permanently.
   Do not use highly powerful jets.
   Carefully wipe down your bike and make sure it is dry.
2. Lubrication:
   Use Vaseline-type oil for the cables.
   After washing, lubricate the gears, the break levers as well as both of the chains.
   The pedals do not need any maintenance: they have been lubricated for the whole of the product’s life span.

As with any mechanical component, a bike is subjected to high levels of stress and wears down. The different materials and components may react differently to use and wear and tear. If a component’s expected life span has passed, it could break suddenly, risking injuring the cyclist. Cracks, scrapes and fading in the areas under high levels of stress indicates that the component has exceeded its life span and should be replaced.

GENERAL CHECKS

Necessary tools for maintenance:

• Small spanner
• Large spanner
• Set of Allen keys of 4, 5 and 6mm
• Medium-sized straight screwdriver
• Small, flat 15mm spanner
• Air pump with a pressure indicator

1. Reflectors:
   Reflectors are an important part of the security equipment of your bike. Never take them off. Every three months check the fastenings of the front and rear reflectors, those on the pedals and wheels, and check that they are securely tightened.
   You should also check the alignment of the front and rear reflectors, the reflective part should be perpendicular to the ground.
   The rear reflector should be placed at least 8 cm below the level of the saddle.
   The reflectors should be kept clean. Make sure you replace any broken reflectors.
2. Cables:
   Replace worn or damaged cables.
   Do not twist cables.
   Cables tend to slacken through use: make sure you adjust them as a result.
   Lubricate cables regularly.
3. Handles:
   Replace worn handles.
   Check that they are completely adapted to suit you.
4. Brakes:
   To increase security, replace the brake cables every 12 months. This is part of the annual maintenance work carried out by authorised bike repair and maintenance workshops./li>
5. Alignment:
   If the parts of the bike are not correctly aligned, take it to your retailer straight away.
6. Wheels:
   The wheels must be centred in the fork slots.
   If the wheels start making strange noises or the breaks start touching the wheel rims, you should have the wheels serviced.
   You must check the wheels regularly to verify the pressure and the alignment of the spokes.
7. Wheel alignment:
   The wheels should turn freely and without rocking.
   Check the bearings on the hub by lifting up the bike and spinning the wheels.
   The wheel should continue spinning round a few times before stopping.
   To check the hub bearings, try moving the wheel rim from either side between the fork. During testing, there should not be any significant looseness/play. If you see that the wheels are loose or that they have difficulty spinning, you should adjust the hub bearings.
   Please contact a bike mechanic who will adjust the hub bearings.
8. Wheel rims:
   Wheel rims should be smooth and free from cracks or bumps. Make sure they are smooth on the inside in order to avoid puncturing the inner tube.
9. Spokes:
   Check regularly that spokes are taut. Each spoke should be equally taut. If you notice significant looseness, you can tighten the attachments with a suitable spanner; however it would be better to take your bike to a bike mechanic.
   If you spot a loose spoke or if the wheel rim demonstrates more than 4mm of lateral play, make sure you have the wheel serviced by a mechanic straight away.
   If you ride with loose spokes, the wheel could give way and this could lead to personal injury.
   A buckled or damaged wheel could lead to uneven breaking and therefore increase the risk of an accident.
10. Tyres:
    If your tyres are inflated correctly riding will be easy, efficient and safe. Make sure they are inflated to the pressure indicated on the sides.
    The tyre should be fitted into the rim correctly.
    When changing the tyre, check that the beading of the tyres and the rims match up.
    When changing the inner tube, make sure it is not caught between the tyre and the rim.
    Check that the tyre does not show:
    • Cracks
    • Evidence of abnormal use
    • Bulging
    • Any faulty tyre should be replaced immediately.
11. Chains:
    Examine the chains regularly to pick up defects and to check the tautness.
    The standard replacement of chains should be carried out by an authorised bike mechanic.
12. 12. Handle bar and pedals:
    The handlebar should turn freely and without any lateral play.
    Check the play of the bearing of the handlebar. To do this, hold the handlebar near the pedal threading and try to move it sideways. If you notice any looseness, get it checked out by a retailer. Make sure you check the bolt screws on the handlebars regularly.
