Protect your ride with the OnGuard Pitbull DT 230mm x 115mm U-Lock, a high-security bike lock engineered for urban commuting, bike storage in high-theft areas, and peace of mind wherever you ride. Built for maximum resistance against theft, this 14mm hardened steel U-lock features the X4P Quattro Bolt Locking Mechanism, which secures the shackle on all four sides for unbeatable protection against cutting, prying, jacking, and twisting.

The included flexible double loop cable adds another layer of security by protecting quick-release components like wheels or saddles (note: not covered by Sold Secure rating).
Ideal for medium to high-risk theft zones, this D-lock for bicycles and scooters includes a Z-Cylinder locking core that is resistant to picking, bumping, pulling, and drilling.
