A new folding bike from Analog Machine Works is redefining portability and style with its unique tetrahedral frame design, enhanced suspension system, and convenience features, promising a fresh option for urban riders.
- Four-fold frame with striking tetrahedron geometry
- Hydraulic adjustable rear suspension for improved comfort
- Competitive crowdfunding price with international shipping options
What happened
Analog Machine Works, a South Korean startup, is launching the Tetra, an innovative folding bike distinguished by its unusual frame design. Featuring an interconnected structure of opposite-facing tetrahedrons, the frame folds at four points, enhancing stability and creating visually appealing proportions rarely seen in folding bicycles.
Beyond its design, the Tetra offers functional upgrades such as larger 20-inch wheels for better comfort on diverse surfaces, a hydraulic shock absorber with adjustable damping at the rear, and reliable Shimano components including a 9-speed sprocket and disc brakes. The bike folds compactly, and practical features like locking wheels and small carry wheels make it easy to transport folded.
Why it feels good
Cyclists often compromise comfort and style when choosing folding bikes, but the Tetra addresses both by combining an eye-catching geometric frame with meaningful suspension improvements. Unlike many folding bikes that rely on simple plastic cushioning, the Tetra’s hydraulic shock absorber helps smooth out uneven urban terrains, enhancing the riding experience.
The thoughtful engineering extends to its portability features. While weighing in at a manageable 13 kilograms, the bike’s folding mechanism keeps wheels together for easier handling, and little auxiliary wheels let users roll the folded bike effortlessly along sidewalks or hallways. This makes the Tetra not just a beautiful design but a practical commute companion.
What to enjoy or watch next
The Tetra is currently available through Kickstarter with an early bird price of $2,390, lowered from its projected retail price of $3,990. Backers should note this is Analog Machine Works’ first crowdfunding effort, adding some risk but also excitement around the launch of this fresh take on urban transport.
As production ramps up in South Korea, international shipping options include the US and various Asian countries at $160 extra, with Europe, Australia, and New Zealand shipping at $220. Riders looking for a standout folding bike experience that marries artful design and everyday usability can watch this project closely as it progresses toward wider availability.
