Notes on cycling in Tianjin What should I prepare for cycling in Tianjin?

About riding a bike, Bian Xiao thinks it needs a lot of physical strength. After all, many people can't hold on. Today, Bian Xiao will tell you what you need to prepare and pay attention to when riding a bike in Tianjin.

When trying to remove new tires, you'd better buy a car with quick wheel removal, so that the front and rear wheels can be easily removed during the journey. Slightly better brand mountain bikes are equipped with quick release wheels. Although the reason is very simple, I think it is very simple when I read it online, but if I haven't dismantled it yet, I'd better dismantle it myself, because if a person travels, he must master his own skills of repairing and changing tires, all of which are based on the premise of successfully dismantling tires. At the beginning of demolition, by the way, observe the structure of the relevant position, so as to be aware of it and not make arrogant mistakes. It's one thing to look at the strategy, but it's another to do it yourself.

There are many tutorials on installing wheels on this website. Let me focus on the rear wheels. Adjust the chain to the smallest circle of the tower wheel when disassembling, and put it back from its original position when reassembling. There is no difficulty in the front wheel. I also want to say a word to my brothers with obsessive-compulsive disorder. When you lock the quick release screw, don't tighten it too much, just seven components. Observe the structure of quick release screw. The function of quick release lever is only to get stuck, not to bear gravity. Moreover, the quick release rod itself is very thin, so it is enough to lock the quick release screw. If you push too hard, you may really break the quick release lever.

After installing the shelf, if it is a short trip, you can ride it with a backpack. After more than 2 hours, it is strongly recommended to install the rear shelf, because it is very uncomfortable to ride for a long time, sweating on the back and then unable to dissipate heat. The weight of the schoolbag will press on your waist and finally press on the contact area between you and the seat, and the shoulder will be sore when the schoolbag is heavy. Many people think backpacks are cool, and the shelf after installation affects the value of the car? no

no

No, countless people's blood and tears tell you that the smaller the backpack, the lighter the better. Everything is on the back shelf, so many things explode. Buy a backpack! However, the distance between Beijing and Tianjin is not high. Basically, they are all necessary pumps, spare tires, car repair tools and water.

There are two kinds of rear shelves, quick-release and mounted in the screw holes of the frame.

If you walk a long distance, the latter is sure to be reliable, but for ordinary small and long distances, the shelf can be competent after being quickly disassembled. There is something wrong with the rear shelf fixed by screw holes. Unless you install it and don't disassemble it, you will disassemble it and screw it again and again. Not afraid of screws, not afraid of aluminum frames. Don't slide the line!

The most valuable and core part of a car is the frame, and other parts can be replaced. Take good care of it. I installed a quick-release rear shelf, and then when the clamp clamps the rear fork, lean down as far as possible to prevent the middle of the rear fork rod from being deformed too much. The rear fork is fixed there with the recommended screw clamp, and it is best not to choose the full quick-release clamp; In addition, you should also pay attention to whether the rear fork of your car is a square tube, a round tube or a diamond tube. Communicate with Taobao shop when buying, or simply go to the physical store to buy and install, and then the fork will not be fixed properly.

Check the front and rear tire pressure. In addition to crumbs, steel wires and nails on the road, there is another important reason, that is, insufficient tire pressure. There is a simple reason. If the tire pressure is insufficient, it is easy to get stuck in the debris and then puncture the tire.

If the tire is filled with air, it will basically bounce off when it meets small debris. When riding a bicycle, you can even hear the sound of small debris bouncing off, especially the rear wheel, which is slightly full and pinched hard.

Check the necessary tools and articles, such as pump, car repair tools, hexagon screws, tire pry bars, wrenches, etc.

As to whether to bring tire repair tools or spare inner tubes, I brought them and bought Jianda inner tubes in advance. All belts do increase the burden, but from the worst point of view, the consideration of multi-belts is as follows: 1, and there is no air leakage point after puncture, and there is no water detection around. 2. It's getting late after the puncture, the light is seriously insufficient or there are other unfavorable environments that are not suitable for tire repair. 3. The location of tire damage is near the valve core. For example, the joint between the valve core and the tire is worn, which is a rugged position and difficult to repair. 4. The tire changing speed is faster and more secure than tire repairing. To sum up, take them all and be practical.

About tire repair. I have to try to make it up at least once. Getting to know it is much better than opening a mobile phone Baidu temporarily. Everything is established in advance, and it is abolished if it is not foreseen.

As for tires, as long as they are new car tires, the basic problem is not big. If the tire is almost worn, for example, it has been worn thin for many years, it is best to replace it with a new one. One thing to pay attention to after a puncture is to clean up the puncture of the outer tire, otherwise the tire will burst again after replacing the new inner tube. It is very important to be careful.

Tips:

Buy inner tubes. There are three points to note: 1. American mouth or French mouth (basically the former) 2. Inner tube size. You can check the label on the tire, such as the size of 26X 1.95.

3. I really don't understand whether the ordinary gas nozzle is longer than the L gas nozzle. If you buy online, show a gas nozzle to the store.

Riding lights at night are not recommended at first, but if possible, you must configure front and rear lights and a flashlight in front to illuminate the road conditions, see the potholes and kerbs clearly, and prevent the car from falling;

Be sure to install a reflector and flashing lights at the back to improve the recognition of vehicles at night. This is related to safety and cannot be sloppy. Charge the headlights in advance and replace the battery.

Vehicle anti-theft problem For bicycles, anti-theft has always been a difficult problem that cannot be completely solved. Do you want to take the car lock with you? If you don't leave the car all the time, it's unnecessary. But cycling is not allowed in many places, so if you want to go shopping or sightseeing, you must lock your car, so I brought two locks, Taiwan Province Li Zhao 9080+ an ordinary password wire lock.

Li Zhaosuo must be locked to outdoor fixtures through the frame, such as telephone poles and lampposts. Otherwise, the lock of the stolen car will be taken away for you! Supermarkets, shopping malls and fast food restaurants are all high-risk areas, and many cyclists will park here. If you don't lock the frame and only lock the front wheel, you will find that there is only one wheel left when you come out, such as this encounter.

My car locking scheme is to lock the frame, and then lock the rear wheel and the frame with a password lock. When there is no pole to lock the car, observe the surrounding situation more. For example, when I visited Tianjin Food Street on the second day of this ride, I was not allowed to go in. I noticed that the guardrail of an air-conditioning plug-in machine in an old-fashioned twist shop could lock the car. I just wanted to try Tianjin Twist, so I went in and bought 2 kg. My aunt in Tianjin is very enthusiastic. After I asked about the car, they asked me to lock the car on the guardrail of the rice transplanter and promised to look after the bike for me. By the way, her twist is really delicious.

Travel preparation (1) Needless to say, charging treasure and data cable, it takes a lot of electricity to turn on GPS, surf the Internet and keep the screen on. By the way, if you forget to bring anything, remember that the convenience store at the gas station can buy Android data cables and the like.

(2) ID card, bank card and cash

(3) You can buy water along the way, and you can take it with you if you are not afraid of weight. It takes about 3 liters of water for one way (Ipoh 550ml X5). I also brought 1 bag of milk.

(4) food. Although you can buy it along the way, it is not a big burden to bring some Snickers and candy, especially for people with low blood sugar.

(5) With regard to sun protection, the sun was already fierce at the end of April, and sun protection was needed. Besides, you can choose leather, but I didn't wear it.

(6) Know the weather before departure: Is it raining? Wind direction? These two have a great influence on riding. Riding against the wind will reduce your strength. When you have low blood sugar, you doubt life. Avoid rainy days, be good for cars and people, and don't touch yourself with "rain or shine". It's only 150 km, so we must choose the right weather.

(7) Book hotels in advance, especially on holidays. When booking a hotel, make sure that the bicycle can be conveniently placed in the room. For example, if it is not in the elevator building, it is also very laborious to carry it to the sixth floor. In short, pay attention to the storage of bicycles. If you are not at ease, you can call the hotel directly to ask.

(8) Most riders should buy cars in physical stores. If conditions permit, they can ask for an invoice and go out for a ride, preferably in their wallets. It may come in handy at a critical time. And it's best to keep your own factory frame number and take it with your mobile phone.

(9) Buy riding accident insurance. On Alipay, the operation is very convenient. Remember to inform your family or friends of the policy information after buying it. Check the equipment one day before departure. It's best to make a list and check them one by one, so give me a picture:

Safety awareness 1. Don't get in the way with big trucks and stay away.

Don't turn a blind eye to the motor vehicle whistling behind you, pay attention.

3. Try to see the front, back, left and right when crossing intersections and turning corners.

Even if it is a green light, don't rush forward. When crossing the road with a green light, pay special attention to vehicles turning right (these vehicles don't need to wait for a red light), and also pay attention to vehicles running a red light.

Some cyclists ride very fast. Many motorists imagine that the speed of riding a bike is the speed of enjoying a bike. When the speed of a bicycle exceeds 30 km/h, I think it will exceed the judgment of many drivers. Pay attention to this, especially when avoiding, learn to put yourself in the other's shoes, and don't think, "I rode so fast, why did you rob me of this car?" Maybe the driver didn't expect you to ride so fast!

6. Give a thumbs-up to the driver who kindly avoided or let you go first, and express your gratitude in time, not to mention meeting by chance.

7.

When riding a bicycle on a parked motor vehicle, be careful that the door suddenly opens. I met cyclists who fell off their bikes and broke the brake handle. Similarly, when riding a bicycle over the door of a parked bus, be careful of passengers who suddenly jump off the bus.

8. Pay attention to all kinds of children. They may suddenly fall down on your wheels. Stay away. If you can't walk far, get off and push. Don't gamble on luck. Don't expect some parents to keep an eye on their children.

9. When you feel tired or your attention drops, you should rest or replenish energy in time. Many accidents happen when you are distracted. When your judgment drops, the wheel will rub against the curb and make people fall.

Quick thinking. Stay awake and sharp!
