It took the designers seven years to gather data, stage bicycle crashes, examine accident data and obtain feedback from a head trauma specialist. They raised $10 million in venture capital to test, design and perfect their design.
But they did it. They did the impossible. They have designed an invisible bike helment, and probably one that will provide better protection from head trauma than those currently in market.
Plus, you'll get to feel the wind in your hair.
As neatly summed up by one of the inventors, "It's chicken to be a realist."
If you are told something is impossible, doesn't that spur you on to prove that it isn't?
