Introducing the HyperBike, a "human-powered traveling machine." Designed for stability, comfort, and exercise. Uses both your hands and feet for power, has no seat, and can go up to 50 miles per hour. The wheels are eight feet tall! This is a prototype. Inventer D.C. DeForest, Jr. is looking for investors.

I hate it when people post overly negative comments, but this thing is just so stupid. The inventor claims that speeds of 50 MPH are possible, but that’s pure rubbish. He’s apparently based that on the gear ratios alone, with no consideration the horrible aerodynamics, the moment of inertia of the needlessly gigantic wheels, or the tremendous weight of the contraption itself. I’m all for pursuing odd pursuits, but don’t try to tell me it’s some sort of design and engineering breakthrough when it’s really just a poorly considered pile of pipe.

That was my first thought. It reminds me a bit of the Segue, which is a way to stay upright and get down the sidewalk... kinda like walking, but more expensive. This bike would be a rich man's toy.
