Chubbs Head Tube

Most folding bikes lack stiffness at the front end. These bikes would have handlebars and stems that flex alarmingly when pushed or pulled. We resolved the problem by lengthening and enlarging the diameter of the head tube, which makes the front end more stiff and rigid.

ClikLok™ Latch

The flip of a single lever folds and unfolds the bicycle. The "click" sound tells you the lock is in place. Another safety hook keeps the lever in place to ensure double locking safety.

PowerBulge™ Tubing

PowerBulge™ frame tubing is manipulated so that it bulges vertically as it approaches the head tube. 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.

PortaWheel

When the bike is in its folded position, our riders can flip out a third wheel, which enables them to push the bike along with
great ease.

QuikFold™ Telescope Handlepost

This handlepost allows riders of all heights to adjust the handlebar to the desirable height. A patented, threadless locking mechanism hides the latch inside the hinge, making the base very clean and streamlined.

Re-Bar™ Technology

Patented Re-Bar™ technology is a break-through frame technology that delivers strength and stiffness while maintaining low weight. The ingenious Re-Bar™ structural support effectively turns a monotube frame into a much stronger, triangulated frame. Many of the mono-tube folding frame designs on the market do not pass international standards for frame strength.

ViseGrip™ Latch

In engineering jargon, our ViseGrip™ latching mechanisms have an exceptionally high degree of mechanical advantage. What this means is that they require little force to operate but are exceptionally strong when locked down. Our aluminum ViseGrip™ latch is forged into a beautifully smooth and sculpted shape that fits your hand perfectly. On the hinge, we have a stainless steel hinge pin and brass bushings between moving parts for a silky smooth folding action. Our steel ViseGrip™ gets the same shape but in stainless steel for improved strength and durability.

WrapAround™ Chain Stays

Most folding bikes have very poor torsional stiffness in the bottom bracket. Our patented WrapAround™ technology wraps the chain stays around the seat post and welds them directly to the bottom bracket. The result is a dramatically stiffer bottom bracket for better power transfer.
