Embed Bottom Bracket

Bottom bracket stiffness is very important for pedaling efficiency but it’s an area where most folding bike designs come up short. On a typical bicycle frame, you’ll find a 90 degree interface between frame tubing and bottom bracket. On bikes featuring our Embed Technology, you’ll find a 300 degree interface. This means that the frame down tube wraps almost completely around the bottom bracket shell for improved stiffness and more efficient power transfer. Dahon patented technology.
