otherwise known as the Aerospoke, is a bicycle "wheel" usually seen on poseur fixed-gear bikes. They are flimsy and heavy motherfucking plastic wheels posing as aerodynamic track wheels, but were actually designed for use on wheelchairs. People who own aerojokes usually drink PBR, listen to unknown bands, have full-body tattoos, and are complete douchebags.
Mommy look, it's a bicycle!
No Johnny, that's not a bicycle. Look at those aerojokes, it's a poseur hipster excuse for a bike.
