Look at the following information, I hope it will help you:
It is very easy to own a bicycle, so more and more people are considering traveling by bike. Traveling by bike requires not only a strong body, but also some basic knowledge. Mr. Deng, the owner of a bicycle shop, wrote to introduce some riding precautions:
As the only means of transportation, the performance of bicycles is very important. Before departure, all parts of the machine should be thoroughly inspected, and common repair tools such as hammer, screwdriver, air pump, wrench and pliers, as well as spare parts such as ball head, inner tube, brake shoe, lathe and valve core should be carried with you. After the end of each day, carefully check the car and solve the problem in time.
Generally speaking, the best angle is a low seat with a backward inclination of 5~ 10 degrees. The arrangement of the amount of exercise should be reasonable, maintain a certain speed, and avoid being fast and slow. Take a rest every 2~3 hours. Don't stop if you want to.
When driving under special road conditions, it is particularly important to grasp the speed. Lu Yu in shallow rivers, puddles, gravel, don't habitually slow down, fast and easy to pass smoothly; When driving on muddy roads, it is advisable to remove the front and rear fenders to avoid mud blocking the gap between the fenders and the wheels; When going downhill, the front and rear brakes should be tightened.
In summer, if you meet the road where asphalt melts, avoid it. There is really no way, just go to the dirt road first and let the wheels touch some loess to prevent sticking.
When camping on the way, the camp should choose a dry and leeward place with water nearby. It's a good idea to spend the night in a village.
Cycling tourism requires strict clothing, especially pants, and it is best to be generous. Wear vest underwear in summer, with low resistance and good ventilation. Sun hat and sunglasses, rain gear, bedding, commonly used medicines, lighting equipment, transportation, topographic map, etc. Are all necessary things.
Now there is a professional bicycle bag, which is very easy to use. Ordinary backpacks must be fastened. When camping, put things in a dead corner that can be covered by your body to prevent them from being lost.
Make necessary preparations before long-distance riding. In terms of hardware, we should do the following: choose a good car; Carry out necessary debugging; Prepare common tools; Bring the right clothes and necessities. Secondly, it is about riding technology.
First, choose a car. It is best to use a 27-inch flat-handle all-terrain vehicle, which is specially designed for long-distance bicycle travel. The front and rear of the car have frames, the speed is 265,438+0, and it can carry 65,438+050 kg (including the weight of the rider). The belts can be selected according to the road surface and load, ranging from 65,438+0.25 to 65,438+0.50 (referring to the thickness). This kind of car is hard to buy in the domestic market at present, but some of them are brought back from abroad by private people. All-terrain vehicles can be replaced by one of mountain bikes (long-distance driving is also considered in the design): 26 inches, 265,438+0 speed, 65,438+020-65,438+050 kg, and the optional belt is 65,438+0.50-65,438+0.75. If you want to take the asphalt road, you can also use a 27-inch fine-grained station wagon with a curved handle. Bandwidth 1.25, with back box. It is very light to ride, suitable for long-distance travel with less load.
Second, shunting. Generally, you can ride and watch while traveling by bike. You are free, and speed is not very important. What matters is convenience and comfort. Diversion according to this requirement. Seat: Put the rider's armpit in the middle of the seat and touch the axis of the roulette wheel with your hand, which is the correct seat height of the rider. The handlebar and the seat should be on the same level and the height should be between half an inch. Check whether the transmission is consistent and whether the front and rear brakes are sensitive. You can put some leakage repairing liquid in the front and rear inner tubes. If there is air leakage, check and pull out the hole, face the hole to the ground, and the belt can be mended automatically when the air is enough. Another way is to put a thick canvas between the inner belt and the outer belt. 1992 I put a canvas in the spring, and there have been no problems so far. With all this work done, this car won't give you any trouble on the road.
Third, tools. As long as you are fully prepared before you leave, the car is adjusted correctly, and there is basically no problem on the road. Just in case, you should also bring some tools and parts that match the bicycle you choose. For example, scissors, Xiao Mu file, multi-purpose hands-on, travel pump (can be installed in the car), glue, cut and filed small pieces of rubber, one for the inner belt and the other for the outer belt, in case of emergency.
Fourth, clothing. Generally, long-distance cycling usually chooses summer, so it is best to choose short cycling clothes, which has the advantage of tight body and no extra resistance. Cycling pants have leather pads or imitation leather pads, which are wear-resistant and breathable. If it is rainy season, of course, rain-proof equipment is indispensable. At present, there is a cycling suit on the market, which is both warm, windproof and rainproof. It is most suitable to go to areas with changeable climate, and of course it is more expensive. If you don't have cycling clothes, especially cycling pants, you can also wear smooth and highly elastic shorts. Direct contact with the body, without wearing any clothes inside. It is best to apply some oil such as vaseline to the parts that are often ground. When the weather is cold, you can line one or two newspapers on your chest, which has excellent insulation effect. In order to prevent wind and small flying insects, you should also wear riding glasses. Colorless, suitable for cloudy days; Colored, can prevent direct sunlight; There are also light yellow ones, which are designed for the night. Helmets, some foreigners like to wear when traveling, in case of traffic accidents. In fact, bicycle hats are more practical, comfortable and economical. Riding gloves are for anti-slip and wear, depending on personal situation. Foot covers can not only help you to have a correct posture, but also save your physical strength. Of course, if you can't use it or are not used to it, you might as well not use it, otherwise it will cause tension, but it will be unsafe.
Fifth, ride. The above can be called hardware, and riding is software, so it is very important to master the correct riding technology. Master the riding speed and get ready to sniff the ball. When traveling in dry areas, you can apply some vaseline oil to the nasal cavity to avoid nasal dryness and ensure smooth breathing. If you need to breathe through your mouth, then you are strong or tired. At this time, you have to slow down and adjust the transmission. When going uphill and downhill, don't change gears at once when using the transmission (people who are not familiar with the transmission often use it), which will make you uncomfortable and more tired. Downhill can relax and slide down. If it is too steep and too fast, use the rear brake to slow down. This is not an emergency. Don't lock the brakes at once, or you will lose a lot of things. Finally, before taking a long bike trip, it is best to take advantage of the holiday to take some short bike trips in a day or two so as to get used to it gradually.
~~~~~~~~~~~~~~~~~~~~~~~~~
Traveling by bike is a complicated game, and it takes a long time to prepare. Even if the specific departure date is determined, it is likely that it will take another week to prepare.
If you want to travel by bike for at least one year, it is essential to keep exercising. If you have good physical fitness, it is more practical to exercise endurance and adapt to the climate. I like jogging, climbing mountains and taking cold showers. I think it's very helpful for cycling long distances. If you travel by bike alone, you need to prepare a lot. First of all, learn the knowledge of travel, and then make a riding plan. The operability of the plan depends entirely on the collection of unknown travel data. The more information is collected, the more specific the plan will be. Maps are one of the most important materials. I visited several bookstores with map counters and the salesroom of Beijing Map Publishing House, and bought a dozen so-called latest national or provincial maps. (It is best to choose national or provincial roads. As long as you look carefully at various versions of the atlas, you will find that there are often great differences, especially the number of kilometers, so you should buy more versions of the atlas to compare with each other. To calculate the kilometers and whether the road is accessible, we must check more data to find out, especially when the road enters and leaves the city, there are the most forks and dead ends, which are the most prone to problems. If you are not sure, be sure to keep your mouth shut and ask for directions. Signs are sometimes unreliable. Signs on the road are all designed for motor vehicles, so it is easy to mislead non-motor vehicle drivers like us to accidentally ride on motor vehicle lanes or highways. There are not many new roads parallel to the old ones on the map. If no one can ask for directions, there will be no people and cars on the new road. Just like the "smart rest", it is safer to take the old one. It's best to take only the useful parts of the map when traveling. If you can't bear to open the book, copy it clearly. A heavy atlas will not bring you any good mood when riding uphill. Maps and other materials should be waterproof. I use a transparent file bag that can be sealed. I put the map I want to see on the outermost two sides of the file bag every day, so I don't have to rummage around. Note that the map should be numbered according to the itinerary, which is also part of the cycling plan. Then you need to plan more backup lines, which will make you more resourceful in the actual situation.
Bicycle may be the real protagonist in your long journey. A good car has many standards. If you ride a long-distance and heavy-duty domestic highway, it is not impossible to ride it like ordinary bicycles, mountain bikes and racing cars, but the fun of riding may be much less. Not to mention the quality of ordinary bicycles below 800 yuan. Cheap mountain bikes have heavy frames and thick tires. The general chevron pattern is not suitable for the requirements of the road, and the friction coefficient is large. After riding for a long time, riding in a mountain posture will be very tired. Although the 700C racing car is easy to ride, it can't carry heavy luggage and has no long fenders. Unless you have backup. Moreover, the national and provincial roads with China characteristics will not let go of the thin tires and body of the racing car. If you like to take the trouble to repair the car and bring N sets of spare parts, that is another matter.
There is a model called an outing car that is more suitable, but it is only available in professional bicycle shops. Generally used for export, it is very suitable for long-distance highway riding. Picnic car is actually a mixture of mountain bike and racing car. The diameter of the wheel is 700C, which is larger than that of a mountain bike, so that the wear of your knee joint will be much less every 1000 kilometers. The tire thickness is generally between 35c and 42c, which is thicker than ordinary tires, but thinner than mountain bikes. Realize the relative balance between load, puncture resistance and portability. It is best to choose smooth road tire for tread pattern of outer tire. If you suddenly brake on the road after loading, the mountain bike tires may slip because the front wheels brake too tightly. Both front and rear wheels of a bicycle should be equipped with fenders, otherwise only the accumulated water on the road will stain your cycling cup and back pocket. In addition, bicycles without fenders are not beautiful. The rear luggage rack should be as strong as possible, and it is best to use a shockproof screwdriver.
Buy a special bicycle front bag, the back bag is generally waterproof, with reflective strips, and valuables are still in the carry-on bag. There is a handlebar bag that can hold maps, which is very practical. It is very convenient to put in the information such as the mileage and map of the day, and even you can read the map while sitting in the car without leaving the handlebar. There is also a bicycle backpack made in Germany, which is characterized by a bracket at the back. The bag and the back are separated and not stuffy. Although the bag itself can be waterproof, it still has a fluorescent waterproof cover, which is too expensive. But if you don't go to mountainous areas and very dry areas, you rarely travel long distances with a backpack with a water bag on your back. Generally, there is only one water cup holder hole on the frame. I was lucky enough to buy an outing car that can hold two water cup holders, because one water cup is never enough. I put water in one cup, and I can put bought drinks or homemade glucose saline in the other. It is more hygienic to buy a suction nozzle with a dust cover when riding a water cup. Picnic cars are also divided into men's and women's models, most of which are men's models. Some also have front and rear shock absorption, but it will increase the weight of the car body, and the front and rear shock absorption is of little use for riding the national road. If it's easier to ride, you can change it to Simano's elliptical roulette, which is not very expensive. Car brakes, brake pads and brake lines must be imported, with good quality, which can't be compared with domestic products. It is best not to use unreliable, unused and unheard-of brands for these life-threatening parts. It is best to replace the handlebar with an adjustable aluminum alloy, and repeatedly debug it to the height that your palm, shoulders and waist think is the least tired. Weight has a great influence on long-distance riding, so the components on the car should be made of aluminum alloy as far as possible, such as handlebars, rims, handlebars, cranks and Zhi Zi. There are few aluminum luggage racks, and some picnic cars have them. It is said that they are made by foreign businessmen. Good quality plastic pedals and fenders are also lighter than metal ones.
Loud electric speakers are more likely to attract the attention of boring people walking in the middle of the road. Drivers who suddenly turn from your side also need to honk a few times. Cycling code table is essential, which can let you know your physical fitness and adjust your progress more reasonably. The most important psychological function is to comfort you when you are exhausted and hopeless about the future, and let you know how far and how long it is from the scheduled goal. Unrealistic plans are also the result of inaccurate calculations. Don't use such a plan to test your psychological and physical limits. In general, the magnetic force of the magnet in the code watch is very small, so it is easy to miss the watch. The most powerful magnet in the world is also a rare earth magnet made in China. There will never be a phenomenon that the magnetic force cannot be detected after the sensor is replaced. Generally, electronic accessories are sold in the market of larger cities. I prefer to use Simano's transmission. Changing gears frequently according to road conditions is good for both cars and people. If the slope is too steep, you have to get off and push. The front and rear axles should be dismantled quickly, and the imported quality is good. Stainless steel slats are more suitable for the humid climate in the south. A good chain won't let you drop it at a critical moment.
It is best not to buy a lock with a cross key. Most professional car thieves have a powerful cross wrench made of special steel. Sometimes picking a lock takes more effort than picking a lock with a zigzag key, and the lock core can be pried open directly. If you bring two locks, both of which are above 40 yuan, the security will be stronger. I usually use telescopic hard locks and chain soft locks.
The car seat is not easy to choose, and the leg movement is inconvenient because it is too wide; Too narrow will be embarrassing; Too hard and uncomfortable; When riding too soft for a long time, the sponge will fill all the gaps between the buttocks and the seat, thus compressing the small blood vessels under the skin. In fact, there is another problem that is my own personal experience. The car seat is vertically convex. After riding for a long time, you will feel that it is trying to break its hips to both sides, which is very uncomfortable. (Fortunately, there are no hemorrhoids) I wonder if other car seats are like this. In order to absorb sweat comfortably, I have also used wing sanitary napkins, which are usually soaked after wearing for half a day. The best way is to change your posture when riding a bike, stop and stand for a rest, not less than ten minutes at a time, and your ass will be more comfortable.
Try not to ride a bike at night unless absolutely necessary. First, there are no street lamps on the national highway at night. Second, the opposite lights are dazzling. Third, the motor vehicles drive very fast at night. In case of a traffic accident, there are few people on the road at night, which is conducive to the driver's escape and is not conducive to being rescued. Although the front and rear headlights of bicycles sometimes feel weak under tunnels and bridge opening, they should be prepared. Reflective plates, stickers or cloth can be added to fenders, car bags and back clothes; Most of the good bicycle headlights are imported and expensive, and many domestic taillights are very cheap; Portable pumps above 60 yuan pump air in both push and pull strokes, and are generally equipped with fixtures; When people leave their bicycles, don't forget to take off the pump and watch; The "iron handle" can make people ride on their stomach and reduce wind resistance, but their hands will stay away from the brakes, and it will be dangerous to brake too late; The handlebar has a brake, but it is replaced by a sitting posture; You can install a small reflector on the left handle and buy a convex mirror. Flat mirrors are useless. Riding a mountain road usually requires a helmet. If you don't have travel insurance, wear them on your head every day, even on a smooth road. Although it is a heavy burden to bring too much water, if you can't replenish water after riding for a day, you must bring a water bag or a small bucket. In hot summer, two glasses of water are only enough for half a day, but small towns along the national highway generally sell bottled water, but the water bag must be kept clean to prevent it from being punctured.
The clothing for cycling in summer should be made of pure cotton, which can absorb sweat in time and evaporate quickly, but not too thick. Too loose clothes will only bring more headwinds, but they can't stop the sweat from flowing downwards. Professional clothing is more expensive, and the price/performance ratio is somewhat uneconomical. I haven't heard of any cheap domestic products yet. Shoes must be light, preferably without shoelaces, and will not slip when stepped on the pedal after being wet. Professional bicycle shoes are too expensive. Some shoes have pedal locks and even separate pedals, which are generally used for racing. In order to do work when lifting legs and pedaling, they are generally not needed when traveling. You'd better buy a riding glove and put it on. If you ride for a long time, your palm will be crushed with blood. There is a kind of fingerless gloves for motorcycles, which are very affordable and better than professional gloves. I also prepared a raincoat with a patent design in the south, which is characterized by holes in the ears and enhanced hearing; The waterproof on the chest is better than that of ordinary raincoats; There is also a windshield under the brim; Very practical. Be sure to give the car license plate before you travel and make several copies with your ID card. If it is an expensive bike, take a picture of it. Some good cars have steel numbers on their frames. Write them down. Before going out, I carved some important information, such as blood type, ID number, contact number, bicycle number, camera body number and so on, on a plastic card, which can be hung on my chest or on a key chain, just like the identification card of the US military, for use when riding alone. I have to buy insurance and make a will every time I travel. Only when you travel in this state of mind will you clearly realize the importance of safety, which is also responsible for your loved ones. At present, there are few foreign insurance companies in Beijing (because there are many such personal travel insurances abroad). Only Ping An Insurance Company in China has a kind of travel insurance online, but it can only be insured online and can only go to 9 cities at a time. It's definitely not enough to cover only these. You can cover them by stages. I only take the planned rest place, because even if something happens on the way, as long as it is on the way to the insurance place, the insurance is valid. The insurance period is also longer than planned, just in case. I usually only take the one-way insurance first, and it is not too late to take the return insurance after modifying my itinerary according to the actual situation at the return point.
Car repair tools are essential, among which tire repair tools are the most commonly used. Merida has a plastic kit, which is not bad. If the front and rear axles are quick-release, there is no need to bring a heavy wrench; If you ride an outing car, you'd better take two spare tires. If you don't have a match at the scene, you should back up any spare parts that may often break down (such as 700C car strips). And bring pressurized canned lubricating oil. Advanced imported accessories are of good quality and generally will not break, but if they break, they will be difficult to repair. It is difficult to guarantee the quality of domestic products, but they can often be taken down for maintenance, but the cost of energy and time may be more than that of buying imported products. Generally, we only repair cars when we can't find a repair shop. Most crowded places have repair shops, so try not to repair your own cars. First, you concentrate on repairing cars and have no time to take care of your property. Second, the cost of repairing your car is far less than the energy you consume, unless you run a repair shop. In order to reduce the chance of repairing the car, try to ride in a clean and flat place when riding a bicycle, and also try to reduce the storage of the bicycle in the sun and rain. The most basic state of a good driver is to slow down in advance according to the car condition and road conditions, and basically do not have to pinch the brakes to reduce the loss of the car. Also, try not to let the bicycle with luggage fall off. If it falls, you don't have to get up and ride again. If Zhi Zi's car breaks down, just put the bike down when parking.
All kinds of medicines should also be brought. It is best to learn some knowledge of trauma first aid and general medication first. Drugs are generally divided into: 1 wound emergency dressing, disinfection, sterilization and hemostasis drugs; 2. Nasal, oral, respiratory and gastrointestinal drugs; 3 colds, analgesics; 4. Drugs for heatstroke prevention, cold prevention, sunburn, scald, burn, snake bite and seasickness; 5 anti-sports injury drugs; 6 various vitamins, trace elements, salt, dry glucose and other nutrients. Prepare a waterproof and moisture-proof bag, put first aid and your commonly used medicine, and carry it with you in a convenient place. Other drugs should also be placed in moisture-proof and sun-proof containers. You can wholesale some small moisture-proof plastic bags with sealing strips in small commodity markets, and other moisture-proof items can also be used. If you ride a bike from the coast to the plateau, you must have a physical examination of altitude sickness. Some people are born unable to live at high altitudes. If you are unlucky enough to catch up, it is wise to appreciate other people's travel notes on the plateau.
Climate is also one of the most influential factors on cycling. The most tiring thing about riding a bike is encountering headwinds, which can completely delay the plan that you think you have saved a lot of physical strength for yourself. Because of the resistance when riding fast, nearly 90% is air resistance. If you catch the downwind, you should repair the brakes in advance. Cycling is most afraid of the sunshine at noon in summer and the ultraviolet rays in the plateau. Even if you don't get heatstroke, you will show several layers of skin. The most dangerous thing about cycling is cycling in the snow. Compared with a car crash, riding into a ditch and falling on the ground is the luckiest thing. When riding a bike in rainy days, you should also feel happy. Thank God, it didn't make worse weather, such as lightning and lightning. Generally speaking, riding for three or four days requires a day off, and it can also be used to stagger bad weather periods.
