Not a mere cardboard cover, this is 100% unicorn bike! Charlie sports a plywood frame and eccentric wheels, Yes, he gallops and prances as he rides down the street. This limits his top speed to a slow jog, but he mesmerizes those he see, often getting "WTF", "SIC", "no Way!" exclamations from those he passes.
Charlie and his pal Pearl have a facebook page with more pictures and videos of them in action.
