Abstract: A hinge for a folding bicycle comprising a first tubular portion, a second tubular portion, the first and second tubular portions being able to assume an unfolded position and a folded position; a blocking element which can assume at least one closed position in which it retains the first tubular portion and the second tubular portion in the unfolded position, and an open position in which it allows the movement into the folded position of the first and second tubular portions; a connection part and a return device configured to bring the blocking element from its open position to its closed position.

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 locking device (5) for locking together a first tube (2) and a second tube (3), the first tube being slidably received in the second tube, the locking device comprising at least one rod (10) mounted to move into two positions and a cam system made up of at least two cams (6, 7, 8, 9) that are mounted on the first tube to pivot either into a first position in which the cams are not in contact with the second tube and allow the first tube to slide inside the second tube, or into a second position in which each of the cams exerts pressure on the inside face of the second tube and prevents the first tube from sliding inside the second tube. The rod is assembled with the cam system and is configured so that it at least moves the cams into their first position, a repositioning system being configured to return said cams into their second position. The invention also relates to a bicycle (1) equipped with such a locking device (5) arranged between a saddle post (2) and a saddle tube (3).

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.
