Problems solved by technology

[0004] In order to overcome the rider's inability to effectively maintain balance and the risk of accidental collision in existing telescopic bicycles, the present invention provides an improved telescopic bicycle, which is not only suitable for riders of various age groups or different sizes It can be adjusted to the frame length suitable for personal riding, especially when storing, it can also be shrunk to a shorter length, which not only reduces the storage volume, but also can be placed in the luggage compartment of a general car as a short-distance transfer (such as between the parking lot and the office) or to the countryside for leisure rides

Description

technical field [0001] The invention relates to a bicycle, in particular to a telescopic bicycle capable of steplessly adjusting the track of the front and rear wheels. Background technique [0002] The bicycle was used as a means of transportation in the early period, and its function was simple and its shape was monotonous. Nowadays, bicycles have been promoted as leisure tools, and the structure of bicycles tends to be complicated, and the shapes are also diversified at the same time. Therefore, bicycles with different functions have come out one after another. The telescopic bicycle is a newly developed functional vehicle after the folding bicycle. Its function is that a bicycle can be adjusted between the front and rear wheels according to the size of the rider through the adjustment of the telescopic mechanism. For the most suitable wheelbase, to achieve the best riding effect; that is, to achieve the function of a bicycle for people of different sizes to ride togethe...
