Patented 4-Fold Space-Frame Bike

Tetra is a tubular space-frame folding bike that pairs compact convenience with a refined ride. Its patented Tetra-fold System adds a fourth fold by collapsing a bridge of opposing tetrahedrons, shrinking the bike to about 25.5 by 25.5 by 13.4 inches for easy storage. A linkage-shock system ties the rear wheel to an adjustable hydraulic shock, delivering smooth suspension uncommon in folders. The chromoly steel frame preserves rigidity through precise hinge geometry. With Shimano disc brakes, a 9 speed setup, and Schwalbe Marathon tires, it is built for daily use. Hand finished and thoughtfully engineered, it brings high quality riding to tight spaces. Back Tetra on Kickstarter now.
