What Does the BullDog U-Lock and Cable Combo Offer?

The OnGuard BullDog Series U-Lock and 4' Cable gives you a complete locking solution in one package. The X2P Double Bolt lock mechanism secures both ends of the 13mm hardened steel shackle simultaneously, delivering a full circle of protection for your frame and primary wheel. The included 4-foot cable lets you loop through a second wheel or accessory without needing to carry a separate lock.

At 4.5 x 9 inches, the BullDog U-lock fits most bike frames and standard urban infrastructure with ease. The keyed format gives you the speed and simplicity of key entry on every stop. It's an especially smart setup for cyclists who want to secure both wheels with one system, making it the go-to choice for commuters and city riders who park at high-traffic racks regularly.
