Medium maintenance air fork every 100 riding hours to the car shop to do maintenance, after the rainy season after the big maintenance hub hub bowl set rear drapillator pedal bearing disassembly check water grease deterioration cleaning and replacement, the speed becomes heavy and the speed is difficult to go to the car shop to replace the line pipe, leisure ordinary (or according to the car below six or seven thousand yuan) resin brake to make the piece five or six thousand kilometers to start to check the degree of wear, this kind of piece do not go to ride the mountain is equal to suicide, high-grade metal sintering to make the piece of flat road 2-30,000 kilometers to check the wear, Ride 10,000 kilometers in the mountains to check, oil dish.

Or the chain of the speed link Taren 10,000 kilometers to check the elongated length to replace, miscellaneous or low-end chain 4000-5000 kilometers to check the elongated length to replace.

Both minor and major maintenance of a bike are important means of keeping your vehicle in good condition, but their main difference is in the scope and frequency of work involved.

Minor maintenance refers to the work carried out before each ride or every 200 kilometers, and mainly involves simple work such as adjusting the brakes and repairing loose ones. This is mainly to maintain the daily operation of the vehicle.

The major maintenance is carried out every 100 riding hours, and the work includes the disassembly, cleaning, debugging and refueling of the whole bike. The purpose of major maintenance is to ensure that the vehicle is in good running condition and to extend the life of the vehicle. Major maintenance can involve a wider range of work, including changing conduits, inspecting and replacing linings, and inspecting and replacing chain talons.

In general, the workload of minor maintenance is smaller and involves fewer components, while the workload of major maintenance is larger, involving more components and maintenance and debugging actions. Whether it is major maintenance or minor maintenance, it is to ensure the normal operation of the bike and improve the riding experience.
