A bicycle (10) includes a frame having a front wheel (12) oriented by a handlebar, a saddle (39), and a crank. The bicycle (10) further comprises two pivot rear struts (18, 19), each carrying a rear wheel (22, 23), the pivot rear struts being mounted on the frame by independent pivot connection means. The crank drive drives the two drives (26, 27, 59, 60) independently of the rear wheel. The drive of each rear wheel comprises a free wheel (59, 60). The driving device is configured so that only the rear wheel located on the inner side of the curve in the curve is driven by the crank, and the rear wheel located on the outer side of the curve freely rotates and is not driven by the crank.
自行车(10)包括车架,车架具有由车把定向的前车轮(12)、车座(39)和曲柄。自行车(10)还包括两个枢轴后支柱(18、19),每个支柱承载后车轮(22、23),枢轴后支柱通过独立的枢轴连接部件安装在车架上。曲柄驱动独立于后车轮驱动两个驱动装置(26、27、59、60)。每个后车轮的驱动装置包括自由轮(59、60)。驱动装置被配置以使得在弯道中只有位于弯道内侧的后车轮由曲柄驱动,位于弯道外侧的后车轮自由转动而不受曲柄驱动。
