提到哥本哈根轮,相信大多数人都不会陌生。早在2009年,美国麻省理工学院(MIT)感应化城市实验室的学生就设计了这么一款自行车辅助工具,该装置可将现有自行车改装成一种混合动力自行车,当刹车时可存储能量,上坡或者行驶疲劳时可将存储的动量释放出来帮助骑行。新版本的车轮几乎可以安装在任何自行车上,将骑手的蹬踏力提高10倍。这一切都是由于驱动系统 Referring to the Copenhagen round, I believe most people are not unfamiliar. As early as 2009, students at the Massachusetts Institute of Technology (MIT) Induction City Labs devised such a bicycle aids that convert an existing bicycle into a hybrid bicycle that stores energy when brakes , Uphill or tired when driving can release the stored momentum to help ride. The new version of the wheel can be mounted on almost any bike, the rider’s pedaling force increased 10 times. All this is due to the drive system
