Abstract: The present invention relates to a suspension system for a bicycle of the type that comprises: a frame (1); a front fork (6) comprising a front damper (8); a swing arm (16) hinged to the frame (1) and a rear damper (25); and at least one shock sensor (30), said sensor (30) being connected to a monitoring unit (28) controlling the front damper (8) and/or rear damper (25) on the basis of the signal sent by said sensor (30); said system is noteworthy in that the front damper (8) and/or rear damper (25) is a variable-compression damper that has at least three positions, an open position in which compression is greatest, a closed position in which compression is zero, and a so-called medium position; and in that it has, as a minimum, means for detecting pedaling called pedaling sensors (29) connected to the monitoring unit (28) which, when pedaling is not detected by the pedaling sensor (29), sets the damper (8, 25) compression command to the open position and, when pedaling is detected by the pedaling sensor (29)

Abstract: The present invention relates to a foldable bicycle of the type including a chassis, a so-called frame (1), on the one hand, and a rear arm (15) firmly attached to the frame (1) and bearing the axis of the hub of a driving rear wheel (16) on the other hand, the driving torque being transmitted to the driving wheel (16) through a chain (17) extending between a driving pinion (13) firmly attached to the frame (1) and a driven pinion (18) firmly attached to the axis of the hub of the driving wheel (16); said bicycle is remarkable in that the rear arm (15) consists of at least two so-called horizontal arms (19a, 19b), one of the ends of which, a so-called proximal end, is jointed to the frame and the other end of which, a so-called distal end, bearing the axis of the hub driving rear wheel (16), is firmly attached to one of the ends of said rear oblique arms (20a, 20b), the other end, a so-called proximal end, of said rear oblique arms (20a, 20b) being provided with male or female firm attachment means capable of
