This bicycle, called the "RELATIVITY Special", if pedaled at 90 rpm, is designed to travel faster than the speed of light.
This is proven by a description of the gear ratios on the sheets seen on the wall behind it. One revolution of the pedals sends the bike 6 times around the earth.
(It is part of the art exhibition "Circle of Time" that Pat Chirapravati curated now on display at California State University, Sacramento).
