For the bicycle users unless you have a problem to every car, it will be lost, and buy a new one, otherwise the maintenance and repair bicycles are not avoidable, On the other hand, maintain good car in getting the failure of the machine rate, also will decrease. Here introduced bicycle maintenance technology, are common, and can DIY (Do It Yourself).
General maintenance of bicycle, can be divided into the following kinds: normal riding use, After a week or ten days) short term (regular maintenance, Medium-term (one or two months) regular maintenance, Long-term (half an year or one year) regular maintenance, Wild emergency repair
In this � � divided according to time, as in daily to cycling twice a week on the above situation to the use of the bike, if you are riding the lower frequency, or your bicycle is frequent, then can use the time to adjust, pp.1 near to suit different riding condition.

Tools
� � so-called sharp tools make good work, must carry on the bike, using the correct maintenance tools is a must, if use inappropriate tools, may cause the difficulty on the job, and even bicycle parts of the damage, so below for general maintenance of tools used must be an introduction. Necessary basic tools

Wrench or open-end wrench: generally spelled r-e-g-u-l-a-r could purchase, open end wrench use more convenient, but must notice when buying more commonly used bicycle for metric bolt, But a wrench, in many work is a must.

� � hex wrench: general metal can be purchased, pay attention to the general use for the metric system.
A screwdriver: there is a word with cross two metal, can be bought.
� � removed when the outer tire pole: remove use, can be in store for car.
� � repair glue and repair piece: with, can be in the car repair shop.
� � dozen chain: remove chain.
� � steel wire wheel wrench: adjust ZhangLiYong circle.
� � lubricants: is not a tool, but is necessary when maintenance, to prepare the butter and oil, and generally chain lubrication oil three.
� � special tools (non-essential, but have the best)
� � socket wrench: use in the disassembly crank fixed bolt, generally for 14mm or 15mm.
� � crank remove: used for removal of crank or big gear disk.
� � chain sprocket wheel wrench: will the decomposition.
� � flywheel remove: will the flywheel, removed from different manufacturers use the flywheel must use different disassembly.
� � HuaGu wrench: for the open end wrench, thin flakes to decompose HuaGu axle and bearing, generally for 13mm 16mm to.
� � fork thin sheets of bowl wrench: used for loading and unloading, open end wrench, adjust the fork bowl of different size fork bowl.
� � rubber hammer stuck to knock the parts:, make its loose.
� � thread clamp: nip is round, cut inside when secure.
� � BB tool used to remove adjustment group, in recognition of the different forms of recognition and have different forms.
� � workbench: used for maintenance, bicycle up.
� � adjustable wheel rims steel frame: adjust tension.
� � third hand tools, used to live in the skin, adjustment brake when braking very convenient.
� � wash clean chain chain: use very convenient.

Normal riding
� � normal riding use is not need any technical, but in the dimension of bicycle, protect the most important and the most basic one in riding bikes to bike before, is very important, is often forgotten, therefore, remember to do before the bike in the following check:
� � check riding position size: if you ride in his car is exclusive, remember riding before seat cushion to appropriate height.
� � check each part of the screw: check and firmness of seat cushion between quick check whether the lock, whether drivers already fixed, other screws are loose.
� � check tyre: check whether the tire pressure, the insufficient enough pressure to appropriate checks whether the womb, wall cracks have appeared, cut the tread pattern is already through shallow, if necessary, to be replaced tubes.
Brakes: try � � check before the brakes, check whether can really "brake brakes.
� � check fork bowl: before the brakes, will halt the front and back, as there are shaking the gap, shaking that must be readjusted before fork bowl.
� � checking transmission: after the start first try to change speed and before respectively after speed, whether can smooth change to the speed, whether there will be strange voices.
Short-term regular maintenance
� � short-term maintenance is often, if the normal use of bicycles, in the order of maintenance, is quite simple, but the maintenance can make your car keep good state, so never neglect.

Do not use water cannons to remove the car body, the methods of sludge, although very efficient, but may be forced into bearing sewage, so will cause damage to the bearing. In the car sludge many situations, should use brush and soap water will wash sludge, rush clean with clear water, reoccupy dry. A clean car lacquer, remember after check whether there peeling paint peeling, steel frame, aluminum alloy corrosion will start after car frame and titanium alloy carbon or not rust, will only affect beautiful. After the car washed in use, remember to dry, and chain to oil.
� � check brake skin: will be on the brakes skin, remove impurities in order to ensure the brake force attrition, if it has been very serious, must update.
� � line pipe to be oiled: if the movement speed brake or bad, may be excessive, the friction outside threats from the outside of the tube to take part, the paint coating, butter, again, if such loading action, still not after considering changing outside threats.
Chain chain will drip oil: after the lubricating oil, about ten minutes later, the chain of oil clean, chain as internal movement is part of the oil is enough, external surplus oil will stick to dust, increase the clean trouble, so best clean.

Check the flywheel and big gear disks: if the update, if the flywheel chain after jumping gears will have the situation, update the flywheel, if big gear disk with great tooth attrition, card should chain replacement, check the big fixed screw loose again, if you should tighten.
� � check wheels: check the gas hole and steel mouth near the hole, whether there is a fine cracks, if have crack, change the wheel rim, will soon raised, wheel rims rotating wheels, observe whether to brake friction, if can, must be readjusted rims.
� � inspection of steel wire: check whether there is sense of fracture, if have the change, change, after the steel wheel rim, re-adjusted must adjust wheel rim, observation wheel rim of direction, such as partial to starboard, it will point to the right of the wheel rim, near the wire loosen lock, left, conversely, slant wide set of wheels amplitude should be less than 2mm.
� � check drivers: check whether the driver in the accident happened in the stand pipe deformation, whether the lock is produced, if the site is updated drivers.

� � examination recognition: remove chain, and as a crank fixed screw, lock, also should adjust, pure bearings, Will rotate, ear cushions, and hear the voice of crank is called "very" - if you hear the voice, smooth the way they jiggle around or other way they jiggle around voice, says bearing damaged, make the recognition of should be replaced.
� � check pedal: tear down pedal, use the open-end wrench 15mm, pay attention to the left of the pedal is teeth, don't open the wrong, don't need to adjust pedal bearings, but still must be checked, if use the cassette pedal, then check the agency action is normal, and oil lubrication. Inspection: check the transmission gearbox each part, if it does, transmission wear has quite serious, should change, if not in oil lubrication action position.
� � shock maintenance: hydraulic shock absorber fork should remove and replace the new oil shock absorber, high interest glue forms of check whether existing cracks or high interest plastic deformation, if any, of the maintenance and update, shock, should inquire of the original purchase manufacturers.
Check all the lacquer that bake, frame: check if there is rustily state to frame shall be replaced, frame, if the frame shock deformation, also should be replaced.
