Tarck is the culture behind taking fixed gear bicycles designed for riding in the velodrome and riding them on the street. This subculture has a strong focus on color-coordination and fixed-gear specific tricks such as skidding or doing a whirly-bird.

Tarck is a track bike ridden on the street, usually with no brakes. It has to have track geometry and track drop bars. It usually has very agressive geometry. Tarck is quite different than a "fixie" in that a "fixie" usually is ridden with a brake or has riser bars.

A tarck bike is a conversion or track bike ridden by a hipster solely on the street for the purpose of looking "cool." More or less internet slang like lol used in real life.
