Abstract
A magnetic bicycle headset includes a first casing engaged with a headtube of a bicycle and a second casing engaged with a fork of the bicycle. A bearing abuts between the first casing and the second casing. The first casing has a first magnet seat for arranging a plurality of first magnets around an axis of the first casing. The second casing has an electrical conductor ring rotating relative to the first magnet around the axis of the first casing. A magnetic field of each first magnet movably passes through the electrical conductor ring. When the electrical conductor ring rotates relative to the first magnets, an eddy current between the electrical conductor ring and the first magnets generates a countering resistance resisting the rotation, so that the present disclosure could reduce a speed and a degree of the rotation of the second casing and the fork relative to the headtube.
