## Description

The OnGuard Bulldog Medium U-Lock delivers strong everyday protection in a compact size designed for urban riders and commuters. Its 13 mm hardened steel shackle helps resist cutting, prying, and leverage attacks, while the X2P Double Bolt mechanism locks both sides of the shackle for added strength and stability. The advanced Z-Cylinder core provides resistance against bumping, drilling, and picking attempts for dependable long-term performance. Protective co-molded crossbar covers and rubber coatings help protect bike frames and finishes from scratches while molded end caps absorb impacts. Designed for practical city use, the Bulldog Medium balances portability and security. Includes 5 laser-cut keys and a universal mounting bracket for convenient on-bike storage.
