Beautifully Build

A folding bike defined by a beautiful tubular space-frame structure. This distinctive architecture enables a precise hinge layout and the integration of a high-performance shock absorber.

Tech : Tetra-Fold System™

The folding structure of Tetra is formed by A pair of triangular pyramids, known as tetrahedrons, open outward and fit together as one unified structure.

This form lies at the heart of Tetra-Fold, defining the bike’s identity.

Tech : Linkage-Shock System™

By integrating a linkage with the shock-absorber system, Tetra is designed to use a high performance shock-absorber while folding even more compactly.
