General information on bicycles

Choosing the correct bicycle size

  • guide image a
    Ordinary bicycle

    A man should be able to place the toes of one foot on the ground with the other foot on the pedal. A woman should be able to place the toes of both feet on the ground while sitting on the saddle in a comfortable position.

    Mountain bike

    The main purpose of a mountain bike is to ride on unpaved roads. This requires a stable bike that is easy to control, and slightly smaller in size than a road bike for the same rider. When the cyclist straddles the bicycle, there should be a space of 8cm or more to the frame.

  • guide image c
    Bicycle for road or long-distance touring

    For a bicycle designed for long distance touring on paved roads, there should be a space of 3 to 5 cm between the upper part of the bicycle (top tube) and the cyclist when he straddles it.

Checking your bicycle

Brake

Check brake pads for wear and twisting; check brake operation by squeezing front and back brake levers one at a time.

Pedals

Check that they are securely fixed.

Saddle

Check that it is properly aligned and securely fised.

Tires

Check air pressure and tread wear.

Chain

Check for wear and corrosion, and keep the chain clean and well-lubricated.

Gears

Check front and rear gear-changing: if adjustment is necessary, it may be necessary to have professional work on it.

Headlamp, rear reflector

Check for damage and sufficient brightness. The headlamp should be white, and the rear reflector should be red.

Simple Maintenance

  • Wipe off dirt and foreign substances from the frame.
  • Use a wet rag to wipe off the frame and then use a dry rag to dry it.
  • Metal parts, except for the wheel rim, should be cleaned with a greasy rag.
  • Tighten all loose bolts and nuts.
  • Lubricate the chain, gears, brake levers, cable and other parts as necessary.

Inflating tires

Types of valves on inner tubes
  • French-style(Presta)valves
    • French-style(Presta)valves image a

      Air pressure can be easily controlled.

    • French-style(Presta)valves image b

      The nut at the tip is loos-ened to inflate and then tightened again.

  • British-style (Dunlop or Woods) valves
    • British-style (Dunlop or Woods) valves image a

      Mainly used in ordinary bicycles air pressure con-trol is difficult.

    • British-style (Dunlop or Woods) valves image b

      The rubber tubing inside the valve needs to be replaced if it has deteriorated.

  • US-style (Shrader) valves
    • US-style (Shrader) valves image a

      Same as automobile tire valves; durability is excel-lent.

    • US-style (Shrader) valves image b

      Press the pin inside the valve to release air pres-sure.

Correct air pressure

Make sure you pump the tire to the correct air pressure using the gauge on the pump, or by checking the firmness of the tire by hand.

  • Correct air pressure image a

    Check the maximum air pressure stated as MAX '00' PSI on the side of the tire before inflating. Pump up to about 80% of the max air pressure.

  • Correct air pressure image b

    If the air pressure is too high, it causes the tire to vibrate, and if the air pressure is too low, the tire is easily punctured.

  • Correct air pressure image c

    After achieving the correct air pres-sure with the help of an air pressure gauge, feel the firmness of the tire so that you can recognize the correct pressure by hand in the future.

Correct use of the bicycle pump

After attaching the head of the pump to the valve, lift up the lever on the pump head to fixx it to the valve.

  • Correct use of the bicycle pump image a

    Do not pump if the lever has not been secured.

  • Correct use of the bicycle pump image b

    The pump has to be well secured so that the pump head and valve do not move around.
