Abstract: A folding moped has a collapsible support for the saddle constituted by two parallel pillars with lower jointed end portions which are inserted within two hollow parts fixed to the frame for sliding between an inserted position in which the pillars are held in an erect condition and a withdrawn position in which the joints project above the respective hollow parts to allow the pillars to be collapsed forwardly.

Abstract: A toothed pulley of pressed sheet metal comprising a first sheet metal element which includes a cylindrical toothed rim connected to a centrally-apertured internal disc lying in a plane perpendicular to the axis of the toothed rim and substantially equidistant from the two circumferential end edges of the toothed rim, a second sheet metal element including a centrally-apertured, internal, flat disc which mates with and is fixed to the internal disc of the first sheet metal element, and is connected to an outer circumferential flange projecting radially from and fixed to one of the end circumferential edges of the toothed rim, and a sheet metal hub which includes a central cup-shaped portion inserted in the coinciding central apertures of the internal discs of the sheet metal elements and has a centrally-apertured, flat, bottom surface for contact with an end surface of the support shaft for the pulley, and a flat, outer circumferential flange fixed to the two discs.
