foldable bicycle

This creation is about a bicycle structure, especially a folding bicycle that can be quickly folded in one hand.

According to the bicycle, bicycle is an extremely convenient means of transportation. Because of the convenience of bicycles, bicycles have become popular. Various bicycles of different styles have been developed one by one, while conventional bicycles are designed to allow riders to ride stably. By the way, the body has a suitable size for the ride, and sufficient weight, so that in addition to convenient riding, there is still a lack of difficulty in going up and down the stairs, pulling into the elevator or retracting, so the conventional bicycle development and improvement is collapsible. Bicycles, in order to overcome the above problems, but the above-mentioned conventional structure is not difficult to find that there are still some shortcomings, the main reason is as follows: the folding bicycle has more than two operation steps when folding, so that riding When the passenger is not necessary, he will not want to fold the bicycle, and the too complicated folding method is not easy to get started and remember, and it will also cost more time to think about how to fold and spend more time. This is the main lack of improvement for the creation. In addition, the conventional folding bicycle is often partially disassembled when folding, such as the snail Or folding off the wheel, etc., not only will there be a time-consuming situation, but there will be a risk of insufficient assembly stability, which will seriously cause the risk of bicycle disintegration during riding. This is also the case of the conventional folding bicycle. Disadvantages.
