Abstract:
1. A bicycle frame, comprising: a chain stay frame member supporting a rear bicycle wheel; a bottom bracket frame member supporting bicycle pedals; a head tube frame member supporting a steerable front fork assembly including handle bars and a front bicycle wheel, the handlebars having a rise and range of handlebar angle adjustment; a straight, curved or angled seat tube frame member adjustably supporting a saddle at a range of saddle heights and mounted at a fixed distance rearward of the bottom bracket at a seat tube angle, wherein the seat tube is mounted, or a seat tube axis as extended from a saddle insertion point, intersects the chain stay or a horn at a distance of at or within a radius of a circle of revolution of the pedals; and one or more interconnecting tube frame members interconnecting the head tube, seat tube and chain stay frame members and the bottom bracket, wherein a combination of the handlebar rise, the fixed distance and the seat tube angle, as well as the ranges of handlebar angle and saddle height adjustments, result in the handlebar angle and saddle height being sufficiently adjustable so that almost all riders, for whom the saddle height can be adjusted for the rider to comfortably sit upright on the saddle and use the proper full leg extension while pedaling, can also comfortably reach the handlebars while riding and fully extend one leg to place a foot flat on the ground while stopped.
