Arthur C. Clarke famously said "any sufficiently advanced technology is indistinguishable from magic". So true! Except in the case of the Zigzain bicycle concept, which appears to be powered by nothing but BS, wishful thinking, and, maybe, genuine magic.
Now it could be me. Maybe a limited understanding of cutting edge BMX bicycle tech is preventing me from seeing the forest through the trees. So I ask, innocently, how do the pedals drive that tiny sprocket without a chain (the design is chainless)? And if they do somehow drive it, how is it more efficient than a traditional chain?
The hubless wheels are a cool touch, I'll admit, but the whole drive chain business has me scratching my head.
Whatever the case may be, you're going to have a hard time convincing me the BMX riders of the future will be using this design to shred the pipe at the Mountain Dew extreme to the MAXX 2020 X-Games. [Falling Pixel via Design Blog]
