OnGuard Pitbull DT Locks

OnGuard Pitbull DT D-Lock – Maximum Security for High-Risk Areas

The OnGuard Pitbull DT is built for riders who need serious protection in medium to high-crime areas. This lock is Sold Secure Diamond rated, meaning it offers the highest level of security available for bicycle locks — trusted by riders, retailers and insurers alike.

Featuring the advanced X4P Quattro Locking Mechanism, the shackle is secured on four sides to dramatically reduce the risk of leverage attacks.

A tough 14mm hardened steel TriRadius shackle provides outstanding resistance to cutting, prying and jacking, while its unique shape creates extra internal space for easier locking around frames, racks and posts. Protective coatings on both the shackle and crossbar help prevent scratches and make the lock suitable for bicycles, e-bikes and scooters alike.

At the core of the Pitbull DT is OnGuard’s Z-Cylinder, designed to resist bumping, picking, pulling and drilling. The rounded body and centrally positioned keyway remove common pry points, while automatic keyway covers keep dirt and moisture out, ensuring long-term reliability in all weather conditions.

For added durability, the lock features all-metal end caps to protect against impacts and drops, along with a co-moulded crossbar cover and double rubber-coated shackle to safeguard your bike’s finish.

Each lock is supplied with five laser-cut keys, including one with a built-in LED light for easy use at night. An all-tube mounting bracket is included for convenient transport, along with a double-loop cable for securing wheels or accessories (not covered by the D-Lock’s Sold Secure rating).

Backed by a lifetime warranty, the OnGuard Pitbull DT delivers confidence-inspiring security when it matters most.
