The invention relates to the field of bicycles, and particularly discloses a bicycle based on a self-adaptive speed change mechanism, which comprises a bridge frame I, the tail end of the bridge frame I is fixedly connected with a supporting column, the front end of the supporting column is welded with a front supporting column, the top end of the front supporting column is fixedly connected with a hoop, and the front end of the hoop is fixedly connected with a handle. The bottom end of the front supporting column is fixedly connected with an inserting frame, a front tire is installed at the bottom of the inserting frame, and the middle of the outer wall of the handle is fixedly connected with a hoop. According to the bicycle based on the self-adaptive speed change mechanism, after the protective frame swings, namely, the protective frame is adjusted upwards, the chain fluctuates inwards and upwards, the chain moves on the two portions of the chain wheel, gear shifting can be achieved, meanwhile, a telescopic mechanism of a telescopic rod is adopted, and when the chain is not adjusted to a flywheel latch in the gear shifting process, the chain is reset through the telescopic rod, so that gear shifting is achieved. And the chain can be input to the clamping teeth with a smaller amplitude on the flywheel.

    本发明涉及一种自行车领域,具体的公开了一种基于自适应变速机构的自行车,包括桥架一,所述桥架一的尾端固定连接支撑柱,所述支撑柱的前端焊接有前支柱,所述前支柱的顶端固定连接有抱箍,所述抱箍的前端固定连接有手把,所述前支柱的底端固定连接有插架,所述插架的底部安装有前胎,所述手把的外壁中间部位固定连接有抱箍。该一种基于自适应变速机构的自行车,在护框摆动后,即护框上调,将会把链条向内上波动,链条将会在链轮二部位进行位移,即可实现换挡,同时采用伸缩杆的伸缩机构,在换挡中,链条没有调节到飞轮卡齿上的时候,经过伸缩杆的复位,即可将链条输入到飞轮上小一幅度的卡齿上。
