意大利发明家吉昂卢卡·萨达设计了一款无辐条的可折叠自行车,折叠后的体积只有雨伞大小,能直接放在书包里。萨达对折叠自行车很感兴趣。在考察一番后.他决定还是自己动手。他研制了几十个原型,最终推出了这个版本。他的折叠自行车最一抢眼的就是无辐条,而最神奇的则是车轮和车架均可以折叠,且体积非常小巧。 Italian inventor Gianluca Sade has designed a non-spoke folding bicycle, folding the size of only the umbrella size, can be placed directly in the bag. Saada is very interested in folding bicycles. After examining, he decided to do it himself. He developed dozens of prototypes and eventually released it. His most eye-catching folding bike is no spokes, and the most amazing is the wheel and frame can be folded, and the volume is very small.
