Bicycles are an extension of human power. Don't wait until the bike is really in trouble before you begin to maintain your bike. From the moment you ride a bicycle, you are closely linked to the bike. In the daily riding process, as long as the heart feels, it is easy to find some hidden dangers, and it can also be adjusted and maintained more naturally.

From the moment you ride a bicycle, you are closely linked to the bike. You don’t just use the bike as a means of transportation to bring him home. He’s your partner. When you are in harmony with your bike, you can naturally listen and observe your car while you are riding, and you can adjust and maintain it more naturally.

listen

In the normal state of operation of any bicycle, it will produce a steady and continuous sound, such as whine, click or soft hum. When cycling, you should listen for unusual sounds. When strange noises appear, you should track the source immediately. If you hear a squeak, you can stop pacing. If the sound keeps on, it may be the wheels. sound. At this point should first stop, turn the front and rear wheels, looking for the source of the strange sound.

Tactile

Touch is a very important sense. When you are in a turn or a downhill descent, if you feel that the traffic is not smooth, you should believe in your feelings. Stop the car to check the tire pressure. If there is no problem with the tire pressure, check the wheels for stability and alignment. When you climb a hill or ride in a standing position for a short climb, you may suddenly feel a click or a strange shock when you step on the pedal. The rattling sound may be due to the pressure of the toothed plate being bent and rubbing against the transmission. The vibration of the foot may be the crank or the foot is loose.

Observed

Once you are accustomed to the way your bike works, your eyes are as natural as your ears. If you happen to watch the chain and the rear derailleur running, you may find that the rear derailleur wheel will suddenly swing back and forth when the chain crosses the tension pulley. This may happen when the chain is locked; or the chain is turning into the teeth. When the disk suddenly jumps up, it may be due to missing or bent corners of the tooth plate. You don't need to specifically look for parts that don't work smoothly, but if you constantly observe, listen, and touch your car with your hands, when problems arise or the machinery is not working properly, you can often spot it immediately.
