the tarck bike is a commonly found variant of the track bicycle or fixed-gear bicycle. unlike true racing bikes used for track cycling races, the tarck bike was formed as a collaboration or "collabo" between bicycle messengers, hip-hop fashion designers, fixed-gear enthusiasts, former BMX riders, and members of national and regional cycling-related internet forums. the tarck bike gets its name from the common, lolcat-esque misspelling of track bike and references this online collaboration.
