SCUL

SCUL (formerly an acronym for Subversive Choppers Urban Legion) is a Boston-area bicycle chopper gang that builds and rides mutant bicycles, chopper bicycles, and tall bikes.

Spun off of a group called the Flying Donuts, SCUL was founded in Boston in 1995. It is organized in a paramilitary fashion with a hierarchical ranking structure, distinct naval/space terminology and a sci-fi atmosphere. Members adopt nicknames and ranks are reset each year. Advancement criteria include receiving a high five from a bystander and crushing cups.
