Abstract
A folding bicycle has a main-frame with a bottom bracket, crank, pedals, and a seat post. A front is attached to the main-frame by a front hinge having an axis parallel to the crank axis, and has a mono-fork suspension. The front frame rotates about the front hinge to a folded position wherein the mono-fork is behind the front hinge axis. A rear swingarm suspension has a rear sprocket and is attached to the main-frame by a rear hinge that preferably is coincident with the crank axis. The swingarm is of a single-stay configuration and is rotatable about the rear hinge to a folded position wherein the rear sprocket is forward of the crank axis. The main-frame may consist of left and right sidewalls spaced apart from one another, and the mono-fork lies at least partially between the sidewalls when the front frame is in the folded position.
