Almost automotive.
Accoding to the notes on the FB thread:
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).
One reply wonders about the need for reflectors and another points out that it's fortunate that it has a lock, because if someone stole it, you'd never capture them.
