The peculiarity of the invention is that it comprises a saddle holder which encloses said frame laterally and is connected to the frame. The holder can be tilted toward the cited frame to bring the saddle forward of the frame. The upper section of the column is connected to the column to permit tilting toward said frame and handle bar sections are connected to the upper column section for tilting against the upper column section.
