PowerBulge™ Technology
To boost the stiffness of our frames, we manipulate our main tube to "bulge" as it approaches the head tube. We call this PowerBulge™ technology. This results in a frame that is substantially stiffer on the vertical plane, where the front end of the bike is most stressed. An additional benefit is that the frame tube also narrows as it approaches the head tube, allowing a more compact fold. Dahon patented technology.
