As the world’s supply of natural resources diminishes, the quest for renewable energy solutions is becoming more and more critical. To help curb the use of non-renewable energy sources, scientist and engineers are tasked with the challenge of finding alternative energies. One of these alternative sources is recovering energy lost to mechanical systems, which could counteract the world's energy shortage. Regenerative braking has already been implemented in hybrid and electric vehicles; however, this paper introduces a regenerative braking system specifically for the conventional, every-day bike. The RE-Brake system recaptures energy that would normally be lost to friction by replacing a conventional caliper brake with a rotating disk that runs along a bike tire’s metallic rim, spinning an electric generator. This recovered energy could be used to power a mobile electronic device. Since hundreds of thousands of people rely on bicycles as their primary method of transportation, RE-Brake, a cheap and user-friendly replacement to caliper brakes, could be used to recover a vast amount of energy and serve as an approach to offset the global energy crisis.
