Problems solved by technology

China is a major producer of bicycles, with hundreds of millions of bicycles. It is known as the kingdom of bicycles, and the export volume is more than tens of millions, which is quite impressive. With the development of social urbanization, traditional big-wheel bicycles have become clumsy, with storage space and weight. Especially the inability to carry it brings a lot of inconvenience to people. Bicycles are a cheap means of transportation. In order to alleviate the excessive congestion of public transport vehicles and the pollution of the exhaust gas emitted by internal combustion engine vehicles to the environment,

Embodiment Construction

[0034] Below in conjunction with accompanying drawing, the utility model of the present invention is further described with embodiment:

[0035] attached figure 1

[0036]Fundamentally different from the traditional and current car body assembly and transmission mode, the research and development uses an unequal triangle structure, the car riser (27), the frame reinforcement plate (24), the rear drive wheel 24, and the big crank disc (21) frame Girder tube (10), the car body that forms, rear wheel (2 / 4), is located at riser vertical line R (27). Big crank dish (21), forms 45 ° of angle overlaps with bottom bracket pipe (20), and angle line presses rear wheel (24) radius structure and transmission mode. Thereby greatly reducing the national body assembly, size, and transmission mode. The saddle upper tube (24) can be lowered into the lower tube (27) to adjust the height of the saddle and reduce the folded size of the brain tank. The saddle can be tilted forward at an angle ...
