Is it appropriate to ride the Sichuan-Tibet line with a 75-liter backpack?
It doesn't fit. It's too big. When riding, you should carry a small bag and put most things on the backpack, because the waist root can't support the weight of 75 liters of backpack and articles after riding for a long time.

When you are ready for a long journey by bike. And have no experience, should pay attention to the following matters:

First of all, be mentally prepared.

Determine the purpose and goal of the trip and establish a firm belief that no matter how long the road is, there will be an end. No matter what difficulties you encounter, as long as you ride steadily, you will certainly reach your destination.

Second, the preparation before departure

First of all, we should collect, consult and sort out all kinds of relevant data and information along the way, including newer versions of maps and traffic maps, as well as geographical, historical, cultural, historical and meteorological data along the way. Then make a detailed travel plan according to your own or team's physical condition, holiday length, travel season and other factors. Generally speaking, the best season for long-distance cycling travel is from May to 10 every year. Long-distance cycling is best to travel together, but the number of long-distance travelers should not be too large. The ideal number is 3 to 5 people, and it is best to have the opposite sex. There are too many people, so it is difficult to get accommodation along the way, and it is difficult to receive in remote small places. Because of the differences in people's personalities and hobbies, it is difficult to act in unison when there are many people. The number of people is too small and the security is poor. And in case of special circumstances on the way, the number is too small to take care of each other. In addition, if the number of people is too small, everyone's relative burden will increase, and some materials and equipment, such as car repair tools and camping equipment, only need one copy.

Third, the preparation of relevant materials

When traveling by bike, the first thing to prepare is a bike. If possible, it is best to choose a 27-inch all-terrain vehicle specially designed for cycling. This kind of car is generally equipped with front and rear frames, which can carry more than 150 kg (including passengers), with good shock absorption performance, portability and firmness, and can adapt to various road conditions. The disadvantage is that it is expensive, and it is difficult to buy spare parts in China at present.

The light bicycle under 26 inches that we usually ride is not suitable for long-distance bicycle travel. You can choose an old-fashioned 28-inch heavy-duty bicycle. If it is a new car, you must run for 200 to 300 kilometers before you go, and then go on the road after comprehensive adjustment. If it is an old car, it should be completely overhauled, especially the processing and transformation of the seat. Car seats should not be too hard or too small. It is best to add a sponge pad with a thickness of 3 to 5 cm. Pay attention to keep the surface of the cushion dry, without wrinkles and seams, so as to avoid wearing the skin or getting prickly heat after riding for a long time. The seat should not be too high or too low, and it is appropriate for individuals to ride comfortably. The handlebar should be basically equal to the height of the seat, and the height difference should be within 3 to 5 cm. You should also install a bag rack at the front and back of the bike. Riding with a backpack for a long time is very tired and uncomfortable. It is best to install a kettle rack on the bicycle beam, so that drinking water can be taken conveniently at any time during riding. In addition, some sealant is injected into the tire. Once the tire has a puncture, just pull out the puncture and pump enough air into the hole, and the hole will be automatically blocked to ensure the continued riding.

Be sure to master the adjustment and repair of bicycles before departure, including; Repair tires, replace car strips, replace brake pads, repair and adjust front, middle and rear axles, and repair flywheels.

Iv. preparation of other materials

Clothing: If you ride in summer or warmer seasons, you'd better buy a specially designed short riding suit. It has the functions of heat preservation, ventilation, wind protection and rain protection. There is also a leather pad in the cycling pants, which is wear-resistant and breathable. Can adapt to riding in various climatic conditions. Just more expensive. If you don't have cycling clothes, especially cycling pants, you can wear elastic tights directly, without wearing other clothes inside, and apply some grease to the parts that are often rubbed. Wear a long-sleeved coat and a sun hat when cycling in summer to avoid sunburn. When riding in winter or in cold regions, besides keeping warm, we should also pay attention to prevent clothes, pants, shoes and socks from being too tight, which will lead to poor blood circulation and frostbite. In addition, you can't wear a mask when riding. If you wear a mask, the exhaled hot air will unconsciously form thin ice outside the mask, causing facial frostbite. The most vulnerable parts of frostbite in winter are ears, nose, hands and feet, so special attention should be paid to the insulation of these parts. The combination of cycling and cart walking can be used to promote and improve the blood circulation of the whole body. Also prepare a rain batch, which has many other uses besides rain protection.

Other equipment: In order to prevent wind and small flying insects from invading your eyes, you should be ready to ride glasses. Colored ones can protect against the sun, colorless ones are suitable for cloudy days, and light yellow ones are especially suitable for night. It is also essential to prepare a small medicine box. Long-term medication includes: drugs for treating diarrhea, gastrointestinal discomfort, cold, acclimatization, anti-inflammation, trauma, eye drops and so on. In summer, we should also prepare some ten drops of water, wind oil essence, cool oil, prickly heat powder and so on. Prepare some chilblain cream, "Cold Pain" and ginger tea in winter. If you are in the northwest, Xinjiang and other places, you should prepare more drinking water (5 to 10 liter per day)

Five, the problems that should be paid attention to in cycling.

The first is riding speed. The speed of riding depends on the physical condition of the whole team, the distance of the road and the length of the holiday. Generally speaking; If the road is flat, ride for about 20 kilometers per hour. Mountainous or hilly terrain, it is more suitable to ride at a speed of 10 ~ 15 km per hour. The daily riding time should not be too long in the first 3 days to a week. It has been 6 to 7 hours a day, and it is more appropriate to ride 120 to 130 kilometers. After the body adapts, it will increase by 20 to 30 kilometers every day, and there will be no big problem.

If you sit for a long time, your feet will be congested and swollen. Lie flat at rest, raise the foot pad as high as possible to promote blood circulation. If there is a small slope, you can also lie down for a while or put your feet on your bike to have a rest.

Because the temperature is too high in summer, riding during the day consumes a lot of energy and is prone to heatstroke, which is not suitable for riding. It is best to choose to ride in the morning and evening.

If you have to sleep outdoors, you should bring a damp-proof pad. Put on dry clothes and pants, put on a raincoat, and lie on a damp-proof mat. And not for too long. Never lie down in wet clothes.

When riding in dry areas, you should apply some grease to the nasal cavity to avoid nasal dryness and ensure smooth breathing. When riding in summer, if you feel dizzy and headache, general weakness, irritability and palpitation, nausea and vomiting, dry and thirsty tongue, sweating and rapid heartbeat, you should lie down in the shade quickly and drink a dozen drops of water immediately. After the body recovers, it gradually moves. Remember not to be cooled by the fan.

When riding in winter, if you feel itchy, red, swollen, numb or even blistering, you should apply it gently with chilblain cream as soon as possible to keep warm locally. Never rub it hard just because it itches.

When traveling by bike for a long time, you must pay attention to food hygiene, otherwise you will get sick halfway, not to mention suffering, and even bring trouble to your companions.

If you feel tired after riding for a long time, you should rest and adjust in time when your legs and feet are weak. Otherwise, due to the decline of control ability, it is easy to cause rollover and collision accidents.

It is also important to be vigilant when traveling long distances by bike and take good care of your belongings, cameras and other valuables. Due to fatigue, distraction and other reasons, it is often prone to relaxation and paralysis. We must be vigilant, otherwise we may not only cause our own economic losses, but also make things worse.

The above is some common sense and basic knowledge about long-distance bicycle travel.

What preparations do you need to make to travel by bike?

cycling tour

First, prepare a suitable bike. After choosing a bicycle, check the vehicle carefully. Frame should be firm and crack-free; Brake should be sensitive and reliable; The spokes of the wheel are moderately elastic, the tires are not deformed, and the valve core is intact; The transmission part is light and free, and the dirt is cleaned and oiled before departure. In addition, check the screws of the whole vehicle and tighten all loose screws.

Second, do some adaptive exercise preparation for the body. You can start one month before departure, exercise for about 20 minutes every other day, and take turns to do standing take-off, squat take-off, sit-ups and long-distance running.

Third, we should prepare a set of simple repair tools: wrench, pump, screwdriver, glue, old inner tube (short film for tire repair) and so on.

Prevention and treatment of common diseases in bicycle tourism

catch cold

Symptoms: dry nasopharynx, itching, stuffy nose, runny nose, cough, sore throat, headache, backache, fatigue, loss of appetite, diarrhea, constipation and fever in some cases. Colds are divided into "flu", "cold" and "cold".

Medication: Light patients drink Ganmao Granule, Ganmaotong, Ganmao Capsule, Yinqiao Jiedu Pill, Lingqiao Jiedu Pill and other drugs, while severe patients go to the hospital or the nearest medical point for medical treatment.

diarrhea

This is a kind of "tourism disease", which is generally related to tourism diet. Patients should stay in bed, stop eating for six to twelve hours, and drink more vegetable soup and light salt boiled water. Vomiting and diarrhea can take atropine, berberine or furazolidone. Avoid eating unclean food, drinking boiled water and eating fresh dishes.

suffer sunstroke

It is divided into heatstroke and heatstroke. Symptoms: headache, dizziness, tinnitus, nausea, vomiting, irritability, severe convulsions, respiratory and cardiac dysfunction.

Prevention: Try to avoid activities in the hot sun, and wear a sun hat and sunglasses.

Treatment: Apply warm water to the head and gradually apply cold water. If possible, you can use an ice pack or shower. Take Ren Dan, ten drops of water or scraping, etc. For those who are light, send them to the hospital in time.

Altitude sickness/disease

Symptoms: dizziness, headache, palpitation and shortness of breath. Severe cases include anorexia, nausea, vomiting, insomnia, abdominal distension, chest tightness, facial edema and mild cyanosis. Most people can relax after a rest. In severe cases, sedatives such as phenobarbital, bromadiolone and aminophylline can be taken to guard against the precursor symptoms of pulmonary edema and altitude coma, and inhale some oxygen trauma when acute itching is lacking.

It can be divided into closed trauma, contusion, sprain, open trauma, abrasions, stab wounds, cuts and lacerations.

Treatment: For large open wounds, a doctor must be asked for surgical debridement and comprehensive examination. Smaller open wounds should be washed with sterile physiological saline (or local clean water) to remove foreign bodies from the wounds, then coated with mercuric chloride, and then covered with sterile gauze or bonded with adhesive tape. If there is external bleeding and subcutaneous bleeding, you can use your fingers or dressing to compress and bandage the bleeding place and fix it with a bandage; Pain can be treated with indomethacin and paracetamol. For closed contusion and sprain, various pain-relieving ointment, dampness-hurting ointment, anti-inflammatory ointment can be externally applied for hot compress, physical therapy, massage and massage, and medicinal wine, powder and pills can also be taken orally or externally.

venomous snake bite

Whether it is poisonous or not: if there are two particularly thick and deep tooth marks at the top of the two rows of tooth marks, it means that they have been bitten by poisonous snakes; If it's just rows of serrated teeth marks, it means it was bitten by a non-poisonous snake.

Treatment: no special treatment is needed after being bitten by a snake, just apply mercuric chloride and iodine to the wound and bandage it; If you are bitten by a poisonous snake, you should tie your limbs with a band at 5cm near the wound as soon as possible, and relax the band every half hour 1-2 minutes. At the same time, the venom in the wound should be removed. It is best to wash the wound with hydrogen peroxide or 0. 1% potassium permanganate to destroy the poisonous juice, or use cold boiled water, salt water or clean raw water instead. After washing, use a sterilized knife or blade to scrape the skin between the two fangs. You can suck the wound directly through your mouth, spit it out immediately after inhalation, and rinse your mouth with clear water. However, if you have dental caries or oral mucosa or lips are damaged, this method is prohibited to avoid poisoning. You should take the medicine as soon as possible: take 80-90 tablets of Lobelia Chinensis orally, mash Lobelia Chinensis and Realgar together, make it into paste and apply it externally, and change it daily. Good snake medicines include Zhanjiang snake medicine, Nantong snake medicine, Guangzhou snake medicine and Sheshang Jiedu tablets.

How to do self-care in cycling self-help tour

Riding, especially cycling, has problems that are not easy to encounter in other modes of travel, so we need to pay attention to:

Friction between the inner thigh and the seat cushion is easy to cause skin abrasion; Local sweating is prone to immersion dermatitis. Therefore, after riding for a certain distance, you should get off and rest to dry. After going to the rest place at noon and night, you should change your sweaty underwear, wash and dry your perineum and inner legs, and then you can prepare some Chinese medicine pine pollen. If it breaks, it should be treated as a scratch, and if it is serious, stop riding.

The car cushion oppresses the perineum, prostate, scrotum and urethra for a long time. It is easy to cause congestion, poor urination and easy reproduction of bacteria. Therefore, you should get off the bus for about 60 minutes on the way, relax the oppression and urinate in time. Hips (under the umbilicus when sitting) should be bathed and cleaned in warm water for 10~ 15 minutes, which is equivalent to hot compress.

Hold the handlebar tightly with both hands, and the nerves in the ischium and pubic bone are compressed, which is easy to numb for too long. Therefore, you should wear gloves when riding a bike, preferably elastic, and the holding angle and method of your hands should be changed frequently; When sitting, you should also change the "focus" from front to back, left and right, which is conducive to improving the blood circulation of local tissues and relaxing muscles.

Seats should be elastic and soft. The height of the seat is lower than that of the handlebar (faucet). The front end of the seat leans forward slightly with a cushion on it. Tour cyclists should not pursue design requirements based on racing speed, but should pay attention to comfort and hygiene.

Women's menstrual period is generally not suitable for long-distance travel by bike. If they have a basis for exercise and are in good health, there is no need to ban them.

It is more convenient to travel by bike, you can arrange your own itinerary and scenic spots, and you can also enjoy the scenery that is not easy to see when you travel by plane, train, car or group. You can also choose scenic spots according to your hobbies and adjust your stay time. Riding can also hone the will and exercise, which is chosen by more and more short-distance self-help tourists. However, you should do what you can. If you spend all your energy on cycling, you will be very tired at your destination, which is not desirable.

In recent years, more and more people in our country are keen on long-distance cycling, fitness or tourism, investigation and so on. Not only can you exercise and enjoy the scenic spots, but you can also go deep into remote areas with inconvenient transportation, conduct in-depth investigations and experience many little-known customs.

Have a nice trip!

See more cycling forums, especially the Sichuan-Tibet line, which is dangerous and the road conditions are not good. Ask some experts who have already taken this line to give directions.

Isn't there a special camel bag fixed with a 75-liter mountaineering bag? Even if it is repaired, the balance problem must be solved. The two sides are not of the same weight, so nothing is convenient on the road, let alone carrying the things at the bottom of the bag. I suggest you use camel bag, which is convenient and labor-saving, and professional enough.
