OnGuard Pitbull LS 8002
A long Diamond D-lock with a mount, when a Mini won’t close.
Diamond (ordinary bikes)
A longer Diamond Pitbull with a frame mount, useful when a standard Mini will not close around a fat post and you still want the lock on the bike.

Verdict
This helps when a compact Diamond won’t close and you still want a mount. 115 × 292 mm is in the same band as the ABUS 540’s 108 × 300 mm. Specs: 1.75kg, 14 mm, five keys, no cable, frame mount in the box. The ordinary-bike grade is Diamond; there’s no e-bike grade listed. The 540 is Diamond for ordinary bikes and Gold for e-bikes, with a slightly longer shackle. We’d pick this if you want the Pitbull mount and keys on a long shackle.

Who this suits
- Fat posts and cargo frames a 230 mm Pitbull won’t close around
- Ordinary bikes that need Diamond and a frame mount
- Riders who want long-shackle reach without the ABUS 540
Less suitable if
- A compact lock already closes — the STD is lighter
- The policy names e-bike Diamond and you haven’t checked this model
- You need a cable in the box, or a lock sold as anti-grinder
A compact lock that won’t close offers little protection. The LS exists because UK street furniture isn’t all Mini-sized. 115 × 292 mm will take posts the STD (115 × 230 mm) and the Mini-7 (83 × 178 mm) cannot.
Why the long shackle helps
The ordinary-bike grade is Diamond. There isn’t an e-bike grade listed. If you ride an ordinary bike and the policy names Diamond, this lock is a real option with a mount. If you ride an e-bike and the policy names powered Diamond, check Sold Secure — the X1, D1000 and DX1000 are Diamond for both. The 540 is Diamond for ordinary bikes and Gold for e-bikes.
Diamond for ordinary bikes — check e-bikes separately
The 540 is 108 × 300 mm, 1.8kg, two keys, EaZy KF bracket, no cable. This LS is 115 × 292 mm, 1.75kg, five keys, a mount, no cable. Neither is sold as anti-grinder. Choose on cylinder, keys, and the e-bike line — after you’ve measured. If you wanted Hiplok’s larger anti-grinder lock, the DX1000 is 112 × 205 mm: more room than the D1000, not this much length.
LS versus the ABUS 540
The frame mount is in the box. 1.75kg on the frame is a lock you’re more likely to have with you. There’s no cable. A longer shackle also gives a thief more room for a tool. Fill it: frame plus rear wheel if they both fit, tight to the stand. If a Mini already closes on your stand, you don’t need this length — choose the STD, or the Mini-7 if Gold is enough. If you need a metre of chain at home, that’s the New York 1410.
What works well
- Sold Secure Diamond for ordinary bikes,
- 115 × 292 mm — in the same band as the 540
- Frame mount in the box, 1.75kg
- Five keys listed
What to watch for
- No e-bike grade listed
- No cable; not sold as angle-grinder resistant
- A long shackle is more room for a tool if you leave a loop
One thing we’d change
Say, on the same line as the 292 mm, that a long shackle needs filling. Length helps with fit, and it also leaves more room for a tool if you leave a loop.

Pitbull LS or ABUS 540?
Both are long D-locks with a mount. The LS is 115 × 292 mm, 1.75kg, five keys, Diamond for ordinary bikes. The 540 is 108 × 300 mm, 1.8kg, two keys, Diamond for ordinary bikes and Gold for e-bikes. Measure, then read the e-bike line on the policy.
LS or STD 8003?
Same 14 mm family, same mount, same ordinary-bike Diamond. The Pitbull STD 8003 is 115 × 230 mm at 1.44kg. The LS is 115 × 292 mm at 1.75kg. Choose the STD if a compact lock already closes. Choose the LS if it doesn’t.
Will it replace a chain at home?
No. 292 mm is a long D-lock, not 100 cm of chain. For a ground anchor or a garden post, see the New York 1410.
Is this anti-grinder?
It isn’t sold that way. Diamond is the Sold Secure grade. If anti-grinder marketing is the reason you’re shopping, look at the X1 or the Hiploks — and still measure your stand.
If you haven’t measured your stand yet, start with how to choose a bike lock. You can compare the shortlist on best bike locks UK, or read D-lock vs chain.
