Abstract: A foldable bicycle provided with a frame, the frame comprising a first arm having a rear end to which a rear wheel is linked, a fork with handlebar to which a front wheel is linked, a bar connecting a front end of the first arm to the fork and hinged to the first arm and a post supporting a saddle and hinged to the first arm. The first arm, the bar and the post are interconnected by transmission elements for simultaneously rotating about the axes between an operative configuration and a carrying configuration. The transmission elements comprise a first engagement angular sector rotatably coupled with said post via first linkages, and a second engagement angular sector in rotary engagement with the first engagement angular sector and rotatably coupled with the bar via second linkages.
