Logic suggests that a bigger, heavier bike lock is a better bike lock. But if you’re carrying an 8-pound U-Lock in your pack, the 2.2-pound Litelok will sound pretty good. It also looks cool. Litelok’s creators used multiple innovative lightweight materials to create the composite strap, a material they call Boaflexicore. This material can withstand sustained attacks from hacksaws, bolt croppers & cable cutters. A funded Kickstarter project.
