Pink Guy appears to have several different modes of transportation (including a blue truck -- extra Pink Guy bonus points to anyone with a photo!) Here's Pink Guy's pants and one of his bicycles, spotted near 4th east and 7th East.
This site is devoted to the scientific study of Pink Guy, Pinkius locomaximus utahnius.
