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. Bike is a tool for weight loss, according to statistics, 75 kg, with 9 miles an hour and a half speed, riding 73 miles, can reduce half a kilogram of body weight, but must persevere every day. Cycling movement, not only can reduce weight, also can make your body more fit and attractive. Exercise for weight loss, or go on a diet and exercise, the body is better than on dieting alone, more attractive. Proper exercise can secrete a hormone, this hormone to make your mind open and bright, cheerful. From experience, can know cycling can produce this hormone. In fact because of cycling compression of blood vessels, making blood circulation acceleration, brain intake more oxygen, so you breathe in more fresh air. After riding for a while, you will feel brain more clearly. Ride the physical strength to go on the two-wheel bike by itself, you will feel very free and very carefree. It is not just a kind of motion reducing weight, but also the exile of heart.

The advantages and disadvantages of power quality

Mountain track as a result, power quality mountain bike athletes merits a great impact on performance. This Three wheel bikes through the consult literature with his coaching experience, mountain bikes for the strength training of the players were discussed. 1 power quality and training outline quality refers to the body's neuromuscular system the ability to overcome or Folding electric bikes resistance at work. On the basis of the division of different can be divided into different categories, according to the relationship of sport-specific can be divided into general and special forces; According to the relationship of athlete's weight can be divided into absolute power and relative strength; Needed to complete the different sports activities according to the different characteristics of the power quality can be divided into the biggest power, fast strength and endurance.

A top speed of bicycles

Bicycle top speed of 268.831 kilometers, is on October 3, 1995 by the Dutch Fred roma's bell by bonner, salt flats in Utah in the United States. This Folding electric bikeswas in large part thanks to his leading vehicle produced by low pressure air pockets. And people's normal walking bike is 15 km per hour. Chrome molybdenum steel frame: 90 s, bicycle frame with chrome molybdenum steel system for the mainstream. Its distortion performance and good Three wheel bikes properties, high temperature will not affect the material, when welding the price is cheap. But the weight is heavy, easy to oxidation. Appeared to overcome its shortcomings, give play to the advantages of the new material, chrome molybdenum steel frame again. Carbon fiber frame: light and absorb the impact of the ground, quick material of backwash force, etc., is the ideal bike frame material. Carbon fiber grade, tonnage high elasticity are also higher and higher, the price is expensive. There are several kinds of methods, such as with adhesive on the mould, overlapping carbon fiber, heat treatment, solidification, molding, etc. The proportion of titanium frame, titanium is 55% lighter than steel, it is not easy to oxidation. In order to improve the tensile strength, has mixed aluminum, vanadium and titanium alloy. Such as welding needs to be done in a vacuum processing complex, frame price expensive. Aluminum frame, aluminum alloy frame of light and strong rigidity. After special processing a frame of only 1 kg in weight. Aluminum pipe tends to large diameter, to alleviate the too strong rigidity, small cars fork pipe and adopt absorb the impact of carbon fiber and other popular attention.

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.

The bicycle has been the most closely relationship with People's Daily life one of the means of transportation

The bicycle has been the most closely Three wheel bikes with People's Daily life one of the means of transportation. While science and technology highly developed today, there are a lot more comfortable, fast and convenient transport than bicycle, but a people-oriented of transportation Cargo bike bicycle are more and more be favorred, and become an important part of urban traffic. Thinking from a different Angle, which requires the design of the bike, to be on the basis of ergonomics, can not only emphasis on the function of the bicycle, and ease of use and entertainment at an organic whole, meet consumer needs at all levels, that bring the vibrant life personality. As a result, the man-machine analysis was carried out on the bike has the vital significance. In this paper, from the perspective of ergonomics, the development of bicycle design the human element and bicycles, bicycle design, design the man-machine relationship analysis and research. Bicycle design is discussed, and the development, from the perspective of historical evolution, combining with the characteristics of bicycle the modelling of various periods, such as structure, material, color, design elements analyses the development characteristics of bicycle appearance modelling design, predict the future trend of the development of bicycle design: bicycle will be toward miniaturization, lightweight, rich personalization and humanity, science and technology, variety and development direction, such as antique. So as to satisfy a particular population, but also embodies the pursuit of a kind of the idea of humanization and individualized.

Electric bicycle production enterprise

A kind of electric motorcycles, electric cars, is a kind of appearance is similar to the motorcycle, but in a storage battery to drive the motor drive. Driven by electric motorcycles. Divided into two wheel, electric motorcycle and electric three-wheeled motorcycle, electric motorcycle, driven by electricity, maximum design speed of 50 km/h two rounds of motorcycle. Electric motor tricycle: driven by electricity, the Folding electric bikes design speed is greater than 50 km/h, the vehicle kerb mass less than 400 kg of three-wheeled motorcycle.Electric bicycle production enterprise and national institutes, colleges and universities cooperation, system upgrading of the technological content of products, the formation of technology and products with independent intellectual property rights, continue to stay ahead in the Three wheel bikes of the techniques of electric bicycles in the world. Four national standards for electric bicycle is the most main: there must be a foot can realize human cycling; The highest design speed is not more than 20 km/h; The mass is not more than 40 kg; Motor output power is not more than 240 w.
