the reason why China is called "the kingdom of bicycles"

Driver only one thousand title of "the kingdom of bicycles" registered in China is a myth, the reason why China is called "the kingdom of bicycles", because China is in the number of bicycle ownership and Three wheel bikes in the world. But most only stay in transport at this sense, the bike as leisure fitness is one of the few, where there is little to cycling level. Mention the tour DE France, Han Jiling clearly said China driver is apart from the tour DE France is still some distance, "at the moment we are only a few drivers in a foreign country club, Chinese drivers ring method in field, I think there is still a long way to go." And driver Li Fuyu also think according to the actuality of China bicycle to want to join the tour DE France also electric trike time, "China billions people only more than 1000 drivers, and France has more than 20 registered driver. Many foreign experts believe that China's driver is very lack of competition, exercise, play too little. In France, registered bike race every year, more than 10000, while China doesn't even have one percent." Giant bike bike - international online features: according to the daily mail reported, a Dutch art professional college students collected all kinds of vehicles with from his friends made a giant bike parts, he rode the two meters tall monster in road scene is enough to attract the attention of all people. Walter, 29, the Vatican's bush was a mechanical engineer, currently studying art in college. Walter like with different USES parts making machine "hybrids". Near the graduation, he decided to own hobby further extension, at the same time into the art factors, creating a "big guy".

Bicycle inflatable note right amount

Bicycle inflatable note right amount. Tires under-inflated, resistance increases, driving, outer tube wall on vulnerable to fracture; Inflatable foot, wheels lose elasticity, laboring heavily at tyre force is too large, tire in the cord layer are easy to be broken, shorten service life. In addition, don't ride a bicycle when stored for a long time, also electric trike have the gas played right amount. Can anoint, nor the sun exposure; Bike every coated with the paint coat in the car, not car wax polish, will drop paint; After the bicycle in the rain, with dry cloth blot moisture, prevent rust; To place such as axle, flywheel, front fork, pedal, often should add some Three wheel bikes or oil, flywheel should add some thin oil. The bike with kerosene wash once a year. Note bikes not stored near the heat, the place such as kitchen, coal stove, avoid carbon monoxide gas corrosion. Teach you tips: elastic first lock nut loose, pull brake, brake lining and the circle of the spacing for 3-5 mm, screw tight lock nut again, if the asymmetry of left and right brake lining, should hold is the front and back, or eliminate.so axial flap, brake fork or correction to stick with loose bicycle crank and axis, first find out which side is loose, and then under the loose on one side of the crank support rods, bars the crank pin, tighten the nut. The old car can change a bit bigger crank pin. Such as crank pin wear or crank pin hole enlargement, can be in between the circular arc of the crank pin and axial stick on the pad iron, to prevent loosening. 24 or27 section of transmission, it is usually use 26 tires, 15 to 18 frame, and the front fork with a shock absorber. Mountain bike, is only the general, all no road curved, no small wheels car cushion, people called the mountain bike. Careful friends can discover, mountain bike also have many differences, such as: some front fork shoulder, have a plenty of one shoulder; With the disc brake, V brake; Have a plenty of rigid frame, have a plenty of full suspension frame; Another popular point, some car looks very big, some very fine... In fact, they are all mountain bike, just use different.

Multi-function folding bicycles design research and discussion

Multi-function folding bicycles design research and discussion
Multi-function folding bicycle design background and significance of the bike as a short walking and leisure tools is irreplaceable by other means of transport. But urban development lead to traffic congestion, vehicle storage area is insufficient, lack of bicycle parking places and stolen phenomenon is very serious situation, pressing for bicycle take up less space, easy to carry. The emergence of folding bicycles, better solve the above problems. The current folding bicycles, folding main electric trike is to reduce the occupied space, function is relatively single, not through simple changes with other functions; At the same time around the folded way of folding, folding after modelling is generally quite rough, like a scrap of bike, its outstanding, bones and muscles exposed edges and corners, no folding locking device, can't Cargo bike independently and stand down. To make up for the above defects, this paper designs a new type of multifunctional folding bicycles. The folding bikes "four with a car", in addition to general bicycles instead of walking or fitness function, but also as a shopping cart, after the folding luggage trailer and seat use, unifying the cycling, shopping, transportation and rest. 2 folding bicycles, folding folding scheme analysis scheme is the core issue of folding bike design.

Mountain bike (English for Mountain B Ike, MTB)

Mountain bike (English for Mountain B Ike, MTB), in order to free to roam in the hills, it has a bike stronger than normal, the frame, light outgoing trucks, it is not enough, must also have a flexible and powerful drive system. Along with the advance of human society, accelerating the pace of life, make people eager to return to nature release accumulated for a long time of oppression, and such problems as environment pollution, electric trike shortages, traffic congestion becoming more serious, the global bicycle industry development momentum, particularly aesthetically pleasing, functional diversity of mountain bike is more popular. A 1, the research object, research objects and methods in chongqing, chongqing yongchuan N km on the bullet, chongqing hard stone, chongqing jiangbei sky, the quick feet five mountain bike club as the research object. Investigation content of chongqing's Folding electric bikes bike club, facilities, sports level, investigate the source of funds, etc. , three research methods, literature review related general situation of the literature, events, and mountain bike movement, etc.; Through the Internet and telephone for mountain bike club executives asked interview. Second, the results and the analysis of the number of mountain bike status quo in chongqing mountain bike club. Chongqing mountain bike club so far a total of seven.

lding bicycles

Folding bicycles, the choose and buy: the folding bicycles, fine observation. First observe the surface of the bicycle, the lacquer Three wheel bikes bake lacquer face whether level off, the presence of impurities and clear off color, with or without paint and obvious scratch, frame welding process is fine. Look at the car after folded, front fork, frame and fork after will rub against each other, because often fold, in case the car works. Finally from the frame shape and the coordination of the main configuration to see the vehicle quality, standing behind electric trike wheel of the frame, casing and frame after the left side of the triangle gap is uniform, Stand behind the wheel to see if the front and back on a straight line. If the two are clearly skewed on the vision, this car is definitely a problem. Frame is the most key parts of the bicycle, due to the folding part is active, therefore requires strong corresponding parts, frame should be better than ordinary bicycle to have greater strength. Relates to riding safety brakes, brake is the key to check the brake ago. After folding bicycle wheels are generally small, riding centre of gravity is moving, before the gate is too easy to roll over. See the car weight aluminum alloy material weight under 10 kilograms, the discretion of the price mainly depends on the use of the material and quality. Under 15 kg (sports) to see both the lock of folding bicycles, convenient the folding lock design, and pay special attention to when the choose and buy, otherwise difficult and time-consuming to fold is contrary to the choose and buy intention.

Habitual cycling and gradually expand your heart

In addition, habitual cycling, can gradually expand your heart more. Heart or blood vessels become more and more thin, more and more degenerate, late in life, you will experience it to the trouble, then you will find that cycling is so perfect. Cycling is electric trike a large amount of oxygen movement, there was a old people in six days, completed a 460 km bike travel. He said: "old people should have at least three times a week, make the heart to strengthen, restore normal function. Do you want to make the heart beating, but they should not be too long. So it will be able to adapt to the emergency situation, such as driving or resist." Bicycle exercise at the same time also can Cargo bike hypertension, sometimes more effective than drugs. Still can prevent fat, vascular sclerosis, and to make bones strong. Bike makes you don't need to use drugs to maintain a healthy, and harmless.

It is not just a kind of motion reducing weight, but also the exile of heart.

The purpose of the mountain bike

Mountain biking is mainly of the tread of a lower limb along the circumference of a cyclical endurance and speed endurance sports, Three wheel bikes need to have good physical quality and ideal body conditions, this requires that the coaches need based on the characteristics of the mountain bike project and some objective evaluation criteria, and combined with electric trike experience, scientifically selecting promising young athletes. At present domestic formal mountain bike race more than personal lap time trial, cross-country circle, the project is a mechanical movement, mountain bike cross-country circle more generally a longer distance, mainly on aerobic and anaerobic metabolism is complementary endurance project. According to the rules of the UCI, mountain bike race course should include the woods, fields, roads and mountain road dirt or gravel road, and have obvious climbing mountain and downhill. Course requirements each lap between 6 ~ 9 km. Off-road mountain circle is more collective endurance events, UCI Suggestions under different number of laps of the best game finish time of 90 ~ 90 min, including complete laps of road sections. Mountain bike race movement level is higher, the stronger the aerobic capacity. Aerobic metabolism ability is closely related to the function of the respiratory system, and the extent of the respiratory system developed, and the degree of the size of the body shape, muscular, mountain bike race.
