This bike is called the BlackBraid, and it weighs only 11 pounds. It’s so light that even this little kid can lift it up over her head.
Fast Company explains how this magic happens:
The frame is of particular note. It’s what gives the bike its unbelievable lightness, and it’s also the BlackBraid’s namesake. Crafted from specially braided carbon fiber developed by a partner in Munich, the tubes have incredible rigidity, despite being mostly air. Carbon components have been sourced through much of the rest of the bike as well, including the chainwheel, sprocket, and chain.
That’s cool! But we care less about how it’s made than about how easy it’s going to be to carry this thing up the stairs to our fourth-floor walk-up. And about how we’re going to find the $20,000 to buy one.
