Eight bicycles originated in Europe in the early 20th century. At that time, the bicycle manufacturing technology was not advanced enough, and the size of parts was often limited. One of the important parts, the size of the wheel, has an important influence on the stability, balance and overall appearance of riding.
In the 28 th bicycle, the larger front wheel can increase the riding stability, provide better suspension effect and ride more comfortably. Smaller rear wheels can provide faster acceleration and flexible turning radius. The design of this size ratio makes Baer bicycle suitable for all kinds of scenes, which can not only adapt to the smooth riding of urban roads, but also carry out a certain degree of cross-country in rural areas or rugged terrain.
In addition to the size ratio, the 28 th bicycle has some other characteristics. For example, the integrated frame structure is usually adopted, which is simple and durable. Its rear wheel mostly adopts built-in rear transmission, which is convenient for riders to shift gears. In addition, its front panel is often equipped with drum brakes to provide reliable braking effect.
Bicycle welfare
1, environmental protection and health: bicycles are zero-emission vehicles and will not produce exhaust pollution. Riding a bicycle can reduce the burden of the atmospheric environment and reduce the degree of air pollution. In addition, cycling is an aerobic exercise, which can enhance heart and lung function, exercise muscles and be beneficial to health.
2. Economical and practical: Compared with cars or public transportation, the purchase cost and maintenance cost of bicycles are lower. It doesn't need fuel, but only needs to pay a small amount of maintenance costs, such as shifting gears, brakes and tires. Therefore, cycling can save traffic expenses, especially in short trips.
3. Convenient transportation: Bicycles can provide fast and flexible transportation options in cities and congested areas. It can cross narrow lanes, sidewalks and bicycle lanes to avoid traffic jams and save time. Riding a bike can also make it easier to find a parking space, saving the trouble of finding a parking space.
