Description

forward bending bicycle

technical field

The utility model relates to a forward-bending riding bicycle, which belongs to the technical field of bicycles.

Background technique

At present, there are various bicycles on the market. There are lightweight design racing bikes, simple structure two-wheeled bicycles for transportation, bicycles for specific groups of people, bicycles for specific environments and occasions, multifunctional bicycles, concept bicycles, etc. But among above-mentioned all kinds of bicycles, the bicycle that leans forward is less, and existing bicycle has the function of leaning forward and is only limited to various racing cars, or backrest type bicycle. Moreover, if the racing bicycle rides forward for too long, the rider's waist and back will feel very sore. Therefore, the racing bicycle is not an ideal bicycle for forward riding. Recently, a forward-bending bicycle appeared on the market. Its structure is similar to that of ordinary two-wheeled bicycles. Only the driving mode has been changed. The structure is relatively fixed, which cannot meet the needs of bicycle riders for riding comfort. In terms of speed requirements There are also limitations. With the continuous improvement and improvement of people's living standards, bicycle consumers' demand for bicycles is not limited to safety and function, but also requires that the angle or height of certain structures can be adjusted according to their own conditions when riding, so that the bicycle It is more comfortable when traveling, and it is a kind of enjoyment to ride a bicycle. And these are that bicycles currently on the market do not have.
