You need something quick to loop around a bike rack when you duck into a shop — light enough to carry every day, long enough to actually reach, and secure enough that an opportunist thief keeps walking. The OnGuard OG cable lock is exactly that: 120cm of 10mm heavy-duty flexible steel cable with a pick, pull and drill resistant cylinder, ready in seconds.

The everyday carry lock

Not every lock-up situation calls for a 1kg U-lock. Sometimes you need something you'll actually have with you — light, flexible, quick to use — that still puts up a genuine fight if someone tries their luck. The OG Series cable lock sits in that space: 10mm heavy-duty steel cable with a proper security cylinder, not a padlock-grade afterthought.

10mm steel cable with vinyl protection

At 10mm diameter the cable is at the heavier end for a flexible cable lock — noticeably thicker and stiffer than the 6mm or 8mm cables that come bundled with cheaper bikes. The tough vinyl cover protects the cable from weathering and protects your bike's finish from scratches when you're looping it through.

A cylinder that takes security seriously

The high-security locking mechanism is pick-resistant, pull-resistant and drill-resistant — the same cylinder protection language OnGuard use on their heavier locks. A dust cover keeps grit and moisture out of the keyway, which matters in Broome where fine red dust gets into everything. Two keys are included.

120cm reaches where shorter locks can't

120cm is long enough to loop through your frame and both wheels and around most bike rack posts or fixed objects — without the wrestling match a shorter cable forces on you. It's the length that makes a cable lock actually useful rather than just technically present.

Compact storage strap included

A dedicated strap keeps the cable coiled and compact when you're not using it — in a jersey pocket, a backpack, a handlebar bag or clipped to the bike. Small detail, genuinely useful.

FAQ:

How secure is a 10mm cable lock compared to a U-lock or the OnGuard K9?
Honest answer: a cable lock — even a good one — sits below a U-lock or folding plate lock on the security scale. A determined thief with bolt cutters can defeat a cable lock faster than a hardened steel shackle or link plates. What a quality cable lock like the OG does well is deter opportunist theft — the rider who'd grab an unlocked or minimally secured bike in passing. For short stops in lower-risk spots, it's genuinely effective. For leaving a bike unattended for hours in a busy area, pair it with a U-lock or use the OnGuard K9 or Pitbull instead.

Why choose a 10mm cable over a thinner one?
Thickness directly affects how long it takes to cut through. A 6mm or 8mm cable goes quickly with basic tools. At 10mm you're into heavier cable territory — it takes more effort, more time and more obvious tools to defeat, which is usually enough to make an opportunist move on. It's also noticeably stiffer and more durable over time.

Is 120cm long enough to lock my frame and both wheels?
For most bikes, yes. 120cm gives you enough cable to loop through the front wheel, the frame and around a rack post in a single pass — which is the right way to use any cable lock. If your bike has an unusually wide frame or you're locking to a thick post or bollard, it may be tighter. 

How does the dust cover help in Broome's conditions?
Broome's fine red dust and wet season humidity are hard on lock cylinders — grit works its way into the keyway and causes the mechanism to become stiff or fail over time. The dust cover on the OG's keyway seals the internals when the lock isn't in use, keeping it smooth and reliable for longer.

How do I carry it on the bike?
The included storage strap keeps the cable coiled compactly. Most riders tuck it into a saddlebag, backpack or jersey pocket. It's light enough that carrying it daily isn't a burden — which is the whole point of a cable lock.
