Step 2: After the rear wheel is released and quickly disassembled, you can directly lift the rear shelf and unload the rear wheel. Then slowly pull out the rear wheel.
Note: When removing the rear wheel, try to adjust the chain to the smallest tower wheel.

Maintenance of mountain bike:
1, clean the frame
You can dip a rag in water and spray it on the parts, so that the mud stuck under the frame will soften easily when it meets water. At this time, wipe it with a rag again and you can easily remove the mud. It is not allowed to wash the sludge on the bicycle with a high-pressure water gun, because water can easily enter the central shaft or flower drum, which will affect the service life of the parts.
At this time, it is necessary to pay attention to some places that are easy to accumulate mud on the frame, such as the position of the five-way on the central axis. After washing off the muddy water on the picture frame with clear water, pour a little detergent on the rag and scrub it on the picture frame after simple rubbing by hand. When there is dirt on the frame, just rub it back and forth a few times and the frame will be clean.
It is usually not recommended to use strong detergents such as washing powder, because many bicycles are made of aluminum, and the alkaline components contained in washing powder will react with aluminum, which will lead to some strange color markings in the aluminum part of bicycles over time, so the flexible detergent-detergent essence is definitely a better choice.
2. Wheelsets, headstock and seat tube?
You can choose to brush the sand on the tire with the brush for brushing shoes dipped in detergent. When washing the car ring, it is best to use a rag with detergent instead, and carefully wipe the brake pad on the ring where it has been braked. Simply scrub the spokes. When washing flower drums, don't use a high-pressure water gun to remove detergent. Just soak it in water and wipe it with a clean rag.
When flushing the seat pipe and setting the bag, be careful not to let mud flow into the seat pipe along the seam of the seat pipe clamp. Under the bag, it is often the place where mud flies the most. Carefully wipe off the mud with a rag. For tires, you can use a slightly harder brush to brush off the sand and dust on the tires for simple maintenance.
3. Pointing, forward dialing and backward dialing
The next step is to wash your fingers, which is more complicated. There is more butter in the parts for lubrication. When cleaning your fingers, it is best to gently wipe them with a rag and they will be clean. When cleaning the front dial and the rear dial, the water pipe can be directly aimed at the gap between the front dial and the rear dial and washed with water, so that the mud and sand stuck in the front dial can be washed away. After washing, you can also use detergent to wash off the oil stains on the front and rear dials.
4. Front fork, pedal and brake?
Cleaning the front fork and pedal is very simple. Just wash the muddy water off the pedal. It is best not to wash the front fork with water. When scrubbing the front fork inner tube, wring the water off the rag first, and then wipe the front fork inner tube. After the front fork inner tube is used for a period of time, some impurities will remain on it, which can be gently wiped off with a cotton swab. It is best to get into the habit of keeping the front fork clean, which is also the most basic maintenance for the front fork. When washing the brake (subject to the V brake), you can directly use the water pipe to wash off the residual sediment in the brake to prepare for the next maintenance. ? Brushes can be used to remove dust and small dirt from wheel discs, front and rear transmissions and guide wheels.
5. Tooth plate, flywheel, chain?
These three accessories are the dirtiest parts. Because there is lubricating oil left on the accessories, dust is the easiest to attach. We can use detergent, dip it in water, and then we can clean the tray. When cleaning the dental tray, we can clean each tooth with a rag and then rinse it with water. At this time, the denture is as bright as new. ? The next thing to wash is the flywheel. Wash the flywheel, remove the rear wheel and clean it.
First, release the rear brake, so that the brake will not pinch the wheel. First loosen the screws on both sides of the rear wheel. At this time, gently pat the rear wheel and the wheel will come out. Put the wheel on the ground, carefully wipe it on the flywheel with a rag, put the wheel back in the car, pay attention to the position of the rear dial, and slowly pull the rear dial to put the wheel in. This process is very simple, and you can understand it once or twice.
The last thing to clean is the chain. There are many ways to wash the chain. There are two methods here: the first method is to wash the chain with kerosene and drag the rag around the chain with kerosene. The disadvantage is that it will leave a bad smell for yourself, stained with oil and grease. The second method is to use detergent. It should be noted that when cleaning the chain, it is best to use hot water of about 45 degrees, which makes it easier to play its cleaning role. In addition to wiping the chain back and forth with a rag stained with detergent, it is best to brush each chain slowly with a thicker brush, and soon the black chain will show its original color.
6. Oil the cleaned parts after cleaning, ensure the gear is relaxed, and see if the tire is full of air, but it should not be too full when inflating. I tried to fill them too full. When I left them at home, I had a flat tire. Although this phenomenon is rare, it should be avoided. There are many differences between car maintenance and non-maintenance in service life.
