Given the current income level of Chinese nationals, it will take some time for cars to enter the homes of Chinese people in general. Moreover, from the viewpoints of oil output and sustainable development, China will have some restrictions on the total amount of automobile development, mainly considering the development Fuel vehicles are bound to encounter very serious pressure on resources and the environment. From the perspective of oil resources, China's oil resources are relatively scarce and have once again changed from a net oil exporter to an oil importing country. This concludes that it is impossible to achieve a sustainable development strategy by relying on the import of petroleum fuels for the development of China's automobile industry. In terms of environment, the pollution of vehicle exhaust may become the main source of air pollution in large and medium-sized cities in China. To this end, the development of electric vehicles, electric bicycles is undoubtedly one of the future direction of development. Therefore, China should not take the old path of having private cars in every western developed country. According to the economic level of middle-income urban families in cities nowadays, the average annual wage of workers, salespeople and other general workers in factories and shopping malls is RMB (equivalent to urban per capita income (USD) Yuan of cars, but the maintenance of cars plus the cost of gasoline consumption, including annual consumption of ten thousand yuan, which is equivalent to spend an ordinary staff (the annual salary of people often say that cars can afford, but can not afford. Combined with China's national conditions and the general average family income level, China's big cities have now entered the "motorcycle era." Just as in Thailand today and Taiwan in the previous year, the traffic safety and environmental protection in the urban areas are of the opinion that large and medium-sized cities in China have, and will certainly, tighten their motorcycles more strictly. This is undoubtedly correct. The price of electric bicycles for each about $, close to the price of Qingqi. If the electric bike can go on the road, it provides a labor-saving and green transport for this class that can not afford to buy a car or buy a motorcycle. If you let the electric bicycle on the road, open the green light, as many as tens of thousands of cities, as many as hundreds of thousands of electric bicycles to allow the streets to run, will not cause new traffic jams.
