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.

A foldable bicycle provided with a frame supported on a rear wheel and a front wheel, said frame comprising:
- a first arm having a rear end to which said rear wheel is linked,
- a fork with handlebar, to which said front wheel is linked,
- a bar connecting a front end of said first arm to said fork, said bar being hinged to said first arm about a first axis parallel to the axis of said rear wheel, and
- a post supporting a saddle, said post being hinged to said first arm about a second axis parallel to the axis of said rear wheel,
- said first arm, said bar and said post being interconnected via transmission means for simultaneously rotating about said first axis and second axis between an operative configuration, in which they project at angularly spaced positions suitable for a user to drive the bycicle, and a carrying configuration in which they are collapsed on one another,
- wherein said transmission means comprise a first engagement angular sector hinged about said first axis and rotatably coupled with said post via first linkages, and a second engagement angular sector in rotary engagement with said first engagement angular sector and rotatably coupled with said bar via second linkages.
