Abstract
A bicycle free wheel has a first annular body, at least partially ferromagnetic, configured to be rotatable with sprockets of a bicycle and comprising a first crown gear. A second annular body configured to be rotatable with a rear wheel of a bicycle has a second crown gear matching with and facing towards the first crown gear. The first annular body is axially mobile with respect to the second annular body between an engagement condition in which the first crown gear is coupled with the second crown gear and a disengagement condition where they are decoupled. At least one magnetic body is arranged radially externally with respect to the first annular body, so that the first annular body in the disengagement condition is at least partially contained in the axial space occupied by the magnetic body.
