174,000 bicycle theft incidents are reported yearly in the U.S.; 25% of these involve component theft. This is an especially significant issue for high-end bikes. We aimed to create a high-end bike lock that protects parts left vulnerable by current locks on the market. We focused on two commonly stolen bike parts: the handlebars and the front wheel. We prototyped individual component locks and connected them with theft-resistant chains. Three lock geometries were evaluated for their resistance to bolt cutters, angle grinders, and hacksaws. We designed our lock to be semi-permanently installed to increase portability and stability. Stability tests showed that the additional weight from the lock did not affect safety. Rideability tests were performed with an installed aluminum prototype.
