Fold-able Bike ( Green Lantern’s superhero gear )

Bicycles designs usually take only small departures from the normal look and feel of a bike. Allen Chester G. Zhang threw away all Pre-concept and started anew. His invention is a bicycle that has no spokes, folds to a fraction of its full size, and is a speed demon. The glistening green colors makes the bike look like a perfect addition for the Green Lantern’s superhero gear.

The bicycle uses a direct connection between the pedals and the sprocket covered wheel. Both wheels are held in place by the frame without center spindles or spokes. The curved frame allows the rider to bend comfortably over the handlebars, reducing air drag.

Allen Chester G. Zhang has designed a bicycle that redefines our vision of what is possible on bikes. A visually appealing bike with unique performance elements that would make it a joy to own.



This concept by Allen Chester G. Zhang was designed to be easily transported between work and play. It can be stowed quickly as it folds at the center to create a barely-there yet aesthetically pleasing accessory. Unfold to expose it’s natural suspension shape and gear-to-gear spoke less wheels. Fluorescent copper-zinc components add not only to it’s aesthetic appeal but the rider’s safety. The color choices on this model are a beautiful combination.
