Give your bike the best defense against bike thieves with the sturdy strength and reliability of U-locks.
Many bike riders choose U-locks when locking their bikes in high-risk areas, such as city streets or busy bike racks. Hardened steel construction gives them exceptional strength and more cut and pry resistance than cable locks. Although U-locks are heavier and more rigid than cable locks, they’re designed for superior protection, making them the best bike lock choice for busy urban areas.
Hardened steel U-locks are quite difficult to compromise, which can even help deter would-be bike thieves from attempting to steal your bike. U-locks are designed to resist common theft methods like bolt cutters, sawing, lock picking and prying attacks, making them one of the most secure options for bike protection.
Master Lock U-locks include a carrier bracket that mounts to your bike frame, so you can easily store and transport your U-lock.
