South Korean Startup Unveils Futuristic Folding Bike

Analog Machine Works, a South Korean startup, has introduced the Tetra, a folding bike that prioritizes style and ride comfort. The Tetra features a unique space-frame design, full rear suspension, and larger wheels, setting it apart from traditional folding bikes.

The Tetra's design is inspired by sci-fi concept vehicles, with an exposed tubular frame that gives it a distinctive geometric look. The bike's frame is built around two opposing tetrahedron shapes, improving rigidity and enabling four separate folding points. Once collapsed, the wheels lock neatly together, and a pair of small caster wheels let users roll it around stations or offices rather than carry the entire 13kg weight.

The Tetra's ride comfort is also a notable feature, with a proper rear linkage and an adjustable hydraulic shock absorber. This setup should provide a smoother ride compared to traditional folding bikes. The larger 20-inch wheels also contribute to the bike's stability and comfort.

The Tetra aims to compete with premium folders like Brompton, but with a unique design and improved ride comfort. Analysts say the Tetra's futuristic design could appeal to a wider audience and disrupt the folding bike market. However, the bike's price and availability have not been announced yet.
