A braking system includes a central sprag, connected and perpendicular to the handlebar, projecting towards the front side of the cycle. At the end of the sprag, a terminal is inserted, free in rotation and equipped with two side holes in the lower part through which the flexible metal cable is inserted, which will be connected outside to the common levers activating the front and rear brakes of the vehicle. At the opposite end, on the contrary, the two lugs of the cable will be directly connected to the ends of the knobs of the handlebar. With the adjustment in length of the flexible cable connected to it, relating both to the front and rear braking device, activating one of the two cables placed in the front of the knobs of the handlebar will also pull the complementary cable by the rotation and consequent draw of the mobile central body, so getting a braking action also on the opposite wheel.

A cable brake for a bicycle has a frame and a seat. The frame has a spire formed at a top thereof. A hole is defined beneath the spire for two first cables extending therethrough. The seat is received in a chamber defined in the frame, and has a channel defined therein and a first fastener and two second fasteners provided therein. The first cables are extended in the seat and secured by the first fastener, and connected with two brake levers. Two second cables are extended in the seat through a bottom surface of the frame and secured by the second fasteners respectively. The second cables are connected with two braking means respectively. The seat is suspended in the frame by the first and second cables.

A balanced braking system to be used on a bicycle with a front brake and a rear brake, the balanced braking system comprising: a connecting unit and a secondary cable. The connecting unit is driven by primary cables, carrying a roll. The secondary cable has two ends that connect the front and rear brakes and a middle part that runs around the roll, turning the roll with little friction when shifting. When the primary cables are pulled on, the secondary cable is moved aside by the roll, in turn pulling on the front and rear brakes. Any different forces on the front brake and the rear brake are compensated by the secondary cable shifting with little friction.

A synchronous braking system, comprising a seat, a gliding unit, two primary cables, a secondary cable, a driving element, and a blocking device. The gliding unit is mounted on the seat and, gliding thereon in a linear movement. The two primary cables have a far ends that drive the linear movement of the gliding unit. The secondary cable has two ends that are connected with two brakes. The driving element is mounted on the gliding unit, having a roll, with the secondary cable running over the roll and, when pulled aside by the driving element, driving the two brakes, while compensating nonuniform braking forces by a longitudinal movement. The blocking device is tightly fastened to the secondary cable, restricting the longitudinal movement of the secondary cable to a maximum displacement, so that, if one of the two ends of the secondary cable breaks, with an unbroken end remaining, the unbroken end will still exert a braking force.

A brake system for a bicycle includes a frame with two blocks received therein side by side, each of the two blocks having a protrusion extending from the rear end thereof so that a bridge member is mounted to the two protrusions. Two cables each have one end thereof connected to the respective block and the other end thereof extends through the top of the frame and is connected to the respective brake handle. A rear brake cable connected with the rear brake mechanism is connected to the bridge member and a front brake cable connected with the front brake mechanism movably extends between the two blocks. When either one of the first cable or the second cable is pulled, one of the blocks and the bridge member are moved so that the rear brake mechanism is first operated.
