A body is formed which joins front fork, pedal axle, seat post and rear wheel axle. The body is visually solid from the side--the two open triangles of a conventional tube frame being filled in, and is airfoil shaped from the top. The body has an integral rear fender where the rear wheel penetrates the rear triangle, and assymetrical rear forks in place of conventional rear frame stays. All control cables, and a cargo compartment, are contained within the frame. | |
