Analog Machine Works introduces the Tetra, a folding bike with a distinctive tubular space-frame structure, hydraulic rear suspension, and larger wheels, designed to elevate both style and ride quality in the compact bike category.
- Space-frame design with four folds for stability
- Hydraulic rear suspension adjustable for damping
- 20-inch wheels for smoother urban rides
What happened
Analog Machine Works, based in South Korea, has developed an innovative folding bicycle called the Tetra. It features an elongated tubular space frame comprising a pair of opposing tetrahedrons, which enables the bike to fold at four points. This structure aims to enhance frame stability and create elegant proportions unusual for folding bikes.
The Tetra bike is equipped with 20-inch wheels, larger than the standard tiny wheels seen on many competitors. Its suspension system includes a hydraulic shock absorber on the rear linkage, offering adjustable damping for increased comfort when riding on varied surfaces. After several years of development, the bike is now entering mass production following a successful prototype phase and design recognition.
Why it feels good
Comfort and ride quality are big steps forward with the Tetra. The bike’s larger wheels handle bumps and road irregularities much better than smaller ones, while the sophisticated rear suspension absorbs shocks that typical folding bikes can only mitigate with a small plastic block. This makes daily commutes and trips over uneven pavements easier on the rider.
Moreover, the frame, made from durable chrome-molybdenum steel, balances strength with manageable weight (28.7 pounds or 13 kilograms). The bike folds compactly with a handy hook keeping the wheels locked together, and small wheels attached allow riders to roll the folded bike smoothly along sidewalks or through hallways when not riding.
What to enjoy or watch next
Currently, the Tetra is available for pre-order via Kickstarter, where early backers can get it at a discounted price of $2,390 compared to the anticipated retail price near $4,000. Shipping is offered worldwide, with varied costs depending on region. This campaign represents Analog Machine Works’ debut on Kickstarter, so potential supporters should consider the usual crowdfunding risks.
For those intrigued by urban commuting innovations, the Tetra offers a visually striking alternative to established folding bikes like Brompton or Birdy, with unique features not typically found in this market segment. Watching how this design influences future folding bike models will be worth following.
