A continuously variable bicycle transmission mechanism includes a ring roller, at least one conical planetary roller, a sun roller and a carrier. The at least one conical planetary roller is frictionally engaged with the ring roller. The at least one conical planetary roller is rotatable about a rotational axis of a roller axle of the at least one conical planetary roller. The sun roller is frictionally engaged with the at least one conical planetary roller. The carrier rotatably supports both ends of the roller axle of the at least one conical planetary roller. The carrier is movable along an axis with the at least one conical planetary roller.
