Abstract
A foldable bicycle comprises a frame having a rear portion supporting a rear wheel about a rear axis of rotation, a front portion supporting a front wheel about a front axis of rotation and a hinge system. The hinge system comprises a first part arranged on the rear portion and provided with a first plane surface, and a second part arranged on the front portion and provided with a second plane surface. Inside the first and second parts an actuator mechanism is arranged for actuating a stud that locks or unlocks said parts. The first plane surface and the second plane surface are disposed in a plane that is slightly inclined relative to a horizontal plane, said inclined plane being configured to facilitate pivoting of the front portion relative to the rear portion towards a folded position, in which the rear and front axes of rotation are in alignment.
