A swivel device for bicycles includes a first ring adapted to be mounted on a head tube of a bicycle. The first ring has a plurality of first protrusions formed thereon. Each first protrusion connects to a first brake cable. A second ring is adapted to be mounted on the head tube. The second ring has a plurality of second protrusions formed thereon. Each second protrusion connects to a second brake cable. A positioning sleeve encloses the first and the second rings for positioning the first and the second rings in place. The first ring is able to pivotally swivel relative to the second ring. When braking, the second brake cables dragged to lift the second ring upwardly and the first ring moved upwardly to drag the first brake cables upwardly.
