My invention consists in a peculiar tubular construction of the reach or backbone of the velocipede with socket attachment, whereby, while lightness and strength are secured, top heaviness is avoided. Also, the invention includes a hollow construction of the fork which carries the front wheel, whereby, said fork is made to form oil boxes for lubricating the running axle.
