OnGuard Bulldog STD Bike U-Lock (4.53" x 9.06")

OnGuard bicycle, motorcycle, and powersports locks offer optimal security with the latest technological innovations, quality construction, and ease-of-use all at a great price. The OnGuard Bulldog STD Bike U-Lock offers X2P Double Bolt Protetion Mechanism for four-sided protection necessary against bike thieves. Its hefty 13mm hardened steel resists cutting, prying and jacking while providing ample internal space for locking versatility. Great for commuters, students, and families, OnGuard delivers the meanest locks at the nicest price.


A lock is only as good as it’s weakest link. The patented X2P Double Bolt Protection mechanism secures both sides of the shackle doubling the protection. The lock also presents a round profile and smooth edges eliminating leverage points. Hardened steel utilized in manufacturing of the protective device resists all forms of attack, while shackle coating is protective of finishes.
