OnGuard BullDog U-Lock: Uncompromising Security for Urban & Outdoor Use

Engineered for cyclists, motorcyclists, and outdoor enthusiasts who demand maximum protection against theft attempts, the BullDog U-Lock combines military-grade durability with smart locking technology. Its patented X2P dual-locking system secures both ends of the shackle simultaneously – a critical defense against bolt cutters often overlooked by standard locks.

Key Security Advantages:
– 13mm hardened steel shackle (vs industry average 10-12mm) resists sawing and crushing
– 4.6-ton breaking resistance outperforms 90% of competitor models
– Pick-resistant cylinder with reinforced crossbar sleeve
– Weatherproof design for year-round use in urban bike racks or outdoor storage

Ideal for securing premium bikes (road/gravel), motorcycle accessories, or construction equipment in high-risk areas like city centers or construction sites where theft attempts peak between 8pm-3am (per National Insurance Crime Bureau data).

Weighing just 2.35 lbs yet offering twice the torsional resistance of standard U-locks through our proprietary sleeve reinforcement system. Compatible with all OnGuard alarm systems (sold separately) for layered protection against opportunistic thieves and organized criminals alike.
