A rim structure, in particular for bicycles equipped with a current generator of the variable magnetic field type, comprises a circumferentially extending tubular body ( 2 ) from which a pair of opposite flanges ( 3 ) defining a seat ( 4 ) for housing a tyre (P) extends outwards. According to the invention the tubular body ( 2 ) comprises at least one annular peripheral side pocket ( 5 ) able to house a plurality of permanent magnets ( 6 ) aligned along one circumference. Spacer means ( 7 ) are also envisaged, said means being inserted in the side pocket ( 5 ) in order to keep the permanent magnets ( 6 ) at predetermined distances from each other. |
