The invention relates to a free wheel assembly (10) with front clutches comprising a hub sleeve (11) rotatable on a hub pin (13) and a cassette (25) rotatably mounted on the hub pin (13), a first annular body (15) rotatable on the hub pin (13) and comprising a first crown gear (17), a second annular body (16) associated with the hub sleeve (11) and comprising a matching second crown gear (23) facing the first crown gear (17). The first annular body (15) is axially movable with respect to the second annular body (16) between a motion transmission configuration and a free wheel configuration and coupling members (28) operate between the first annular body (15) and the cassette (25). When the first annular body (15) is the free wheel configuration, a rotation of the cassette (25) with respect to the first annular body (15) forces the coupling members (28) to axially translate the first annular body (15) towards the second annular body (16), and magnetic members (38) are active on the first annular body (15) and are configured to oppose the rotation of the first annular body (15) with respect to the hub pin (13).
