ABSTRACT:
An exposed type, high strength open frame for a scooter has a body frame bottom portion of endless loop form provided at the outer periphery of the lower rim of the scooter body and includes a semi-circular rear connected to opposite, laterally spaced longitudinally extending side bars which merge at the front of the scooter with a head tube having a bore for receiving a steering stem of the scooter. A lateral beam in the middle portion of the side bars connects the side bars and supports an integral, upright inverted U-shaped lateral bent beam. Integral with the lateral beam at the top thereof are a pair of laterally spaced, generally horizontal reinforcing ribs which are connected by straight, upright beams to upwardly and rearwardly directed portions of the side bars forward of the rear bar. A semi-circular head for the main body open frame extends forwardly of the head tube which joins the forward ends of the side bars, or which is integrated to a second lateral beam joining those forward ends of the side bars.
