I’m the creator of Tetra, folding bike
Hi Reddit,
I’m the creator of Tetra, a folding bicycle that launched on Kickstarter yesterday.
I already know what some of you are going to say. "Why a Tubular Space Frame? Why place two hinges on the top tube? That's over-engineered and not the most optimal way for mass production."
You’re 100% right. From a pure, sterile engineering standpoint, there’s plenty to criticize here.
But let's be honest—sometimes we don’t want just 'efficient.' We want a folding bike that looks absolutely badass and makes people stop and stare when we ride it.
To achieve that striking, straight-lined, and aggressive geometric aesthetic inspired by a tetrahedron, a Tubular Space Frame was the only answer. And to keep those gorgeous lines while fitting 20-inch wheels into a tight fold, I spent countless sleepless nights obsessing over how to layout those two hinges beautifully.
I’ve always been obsessed with this raw, mechanical beauty. In fact, when I won the Red Dot Design Award for a previous concept, I finished it in full chrome plating, and the response was overwhelming—people were just stunned by how the light hit the structure. I wanted to bring that exact same jaw-dropping, premium emotion to Tetra.
Because of this complex space-frame construction and the craftsmanship required, it’s honestly expensive. Factory located in Korea not China, It’s not a cheap commuter tool; it’s a statement piece that I poured my engineering soul into.
As an independent developer, the first 48 hours are brutal. I’m not here to just drop a link—I genuinely want to spark a discussion. To my fellow engineers and riders: Does this unapologetic focus on aesthetic and form resonate with you, or do you think I'm crazy?
Thank you so much for reading my story, and I’ll be right here in the comments to answer any technical or design questions!
P.S. I deeply apologize, but due to community rules regarding promotional links, I cannot post the direct Kickstarter link here. If you're curious to see the video and the full design, please search "Tetra" on Kickstarter. I’d really appreciate your support and feedback!
