Chain Reaction is an initiative of Bikes Not Bombs' Bicyclists Organizing for Community Action (BOCA) program designed to help communities in need of bike repairs, resources, or accessibility to nearby bicycle shops.

Additionally, Chain Reaction raises awareness about safe bicycle riding and teaches individuals how to repair their own bikes to increase self-reliance.

Chain Reaction is a mobile bike shop; we bring all of our tools with us which allows us to travel between communities in need. In addition to bicycle repair we also bring information about all of Bikes Not Bombs' programs.
