The body panels and insert completely enclose a continuous internal space which is compression loaded or tensile prestressed with a rigid foam plastic for increased torsional rigidity and resistance to impact distortion. The pedal sprocket and chain are both external of the hollow frame so as to not interrupt the continuity of the body cavity and its compression loading, and also enabling the body to have minimal weight and an optimum aerodynamic configuration. The frame is diamond-shaped in side profile enabling the monocoque to be constructed as a pair of triangles connected back-to-back for optimum strength, both torsionally and against vertical loading. | |
