BioLogic™ Frame Geometry
Small-wheeled bicycles have always been faulted for being less stable than large wheeled bicycles. Many potential buyers who ride a small-wheeled bicycle for the first time find them alarmingly "twitchy". For two years, we rigorously examined the frame geometry of our bikes, with the singular goal of making our bikes as stable as large wheeled bicycles. We've looked at everything from wheelbase, to head and seat angles, to fork offset, to weight distribution, to rotational inertia. Every one of our compact bikes now features our legendary BioLogic™ frame geometry. We can say with confidence that you will not find a better riding or more stable folding bike on the market.
