摘要
Improved bicycle frame, which, starting from conventional general shapes, is characterized in that the vertical inclined element that extends between the saddle and the bearing hub of the pedal axle is formed by means of separate separate bars joined at the top on generatrices opposite of a tubular seat-receiving element, and in its lower part on said hub, so that between the two rods the front part of the rear wheel can be freely positioned, which thus occupies a more advanced position that favors the traction rigidity of the seat.
