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.

Abstract: The invention relates to a foldable bicycle including a frame that comprises a rear portion on which a rear wheel is arranged, a front portion, and a folding system configured to fold back said front portion against said rear portion. On either side of the bicycle, the rear portion has a tubular structure comprising at least one tube extending longitudinally and having a rear segment and a front segment, assembly means being arranged between said rear segments and the rear wheel, said front segments having a curved shape configured to come into contact with the ground or floor when the front portion is folded back against the rear portion, so that said two front segments and at least the rear wheel stabilize the rear portion of the bicycle in the folded position.
