Problems solved by technology

[0002] Bicycle is people's usual means of transportation, and existing bicycle is because the speed of a vehicle is related to the size of wheel, and generally used wheel is all bigger, can not adapt to the people of various ages and heights to use, and quite heavy, lives in the high-rise building It is inconvenient for people to mention it at home upstairs or carry it to other places, and people hope to have a bicycle that is easy to carry
Existing foldable bicycles, due to reaching a certain speed, only fold two larger wheels and frame beams, or also fold the front handle telescopic rod, and still cannot adjust the length arbitrarily according to people of different heights and ages. and height, it cannot be used by people of different ages and heights, and the structure is more complicated, the volume is larger, the weight is heavier, and it is still not convenient to carry

Abstract

The invention discloses a portable bicycle capable of adjusting length and height at will. According to the invention, a telescopic beam for connecting and fixing the front and rear steel tubes can extend to the rear end of the rear steel tube, and the front beam connecting to the front steel tube can be inserted into the rear beam connecting to the rear steel tube. The transmission mechanism of the bicycle comprises four chain wheels and two chains, wherein two of the four chain wheels are installed on the two sides of the inverted U-shaped connecting member end axis, another big chain wheel is installed on one side of the rotary pedal axis and sides with the small chain wheel installed on the inverted U-shaped connecting member end axis, and the other small chain wheel is installed on one side of rear wheel axis and sides with the big chain wheel installed on the inverted U-shaped connecting member end axis. The invention has a simple structure, and light weight, and can run quickly.

Description

technical field [0001] The invention relates to a bicycle, especially a portable bicycle. Background technique [0002] Bicycle is people's usual means of transportation, and existing bicycle is because the speed of a vehicle is related to the size of wheel, and generally used wheel is all bigger, can not adapt to the people of various ages and heights to use, and quite heavy, lives in the high-rise building It is all inconvenient for people to mention it at home upstairs or carry it to the field, and people hope that a kind of bicycle that is easy to carry can be arranged. Existing foldable bicycles, due to reaching a certain speed, only fold two larger wheels and frame beams, or also fold the front handle telescopic rod, and still cannot adjust the length arbitrarily according to people of different heights and ages. and height, can not adapt to the use of people of different ages and heights, and the structure is more complicated, the volume is...
