Abstract
An injection molded, single-piece plastic bicycle frame which includes a generally upright stem, and a cantilever structure joined to and extending from opposite sides of the stem in a gently curving, downwardly facing reverse bend. The material forming the frame has a nonuniform internal structural density which is characterized by higher density adjacent the surface, and by decreasing density progressing toward the core. This material preferably takes the form of a foamed structural plastic material.
