The Prone Bicycle Experiment: Reasoning
The beginning was a single-speed mountain bike geared up for a rapid commute with a little suspension, front and back. As time went on, the gearing rose, pedals clipped and softtail gave way to hardtail with a suspension seatpost. Once speeds grew to a point where the bikepath was no longer a welcome home, the bike had to be made more demanding. Thoughts wandered to charging full time and how to make a ride for that purpose. No matter how far the bars and stem were lengthened and dropped, very little weight could be shifted to the upper body with tradition frame geometry.
Hence, the project. Since the saddle wasn't necessary, the prototype frame was simple once the angles were chosen. A steeper head angle and short rear "triangle" helped balance out the lengthed wheelbase created by the elongated cockpit. The downtube was stretched 12 inches longer than that of a 21" mountain bike frame. a short headtube and mild bottom bracket drop kept the posture as aggressive as possible.
