The OnGuard K9 gives you both. Hardened steel link plates fold compact for transport, unfold to 79cm of near U-lock protection, and lock with a cylinder that resists picking, drilling, pulling and bumping.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eThe lock that doesn't make you choose\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eCable locks are convenient but a decent pair of bolt cutters ends them in under five seconds. U-locks are tough but bulky, and they only reach so far. The K9 sits in a category of its own — hardened steel link plates give you the resistance of a U-lock, while the folding design and 79cm reach give you the flexibility of a cable.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eHardened steel plates, not cable\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eEach link in the K9 is a hardened steel plate — not twisted wire, not braided cable. That means bolt cutters, angle grinders and hacksaw blades face a genuinely difficult job rather than an easy one. At 1kg it has real weight to it, which is exactly what you want in a lock.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eA cylinder that takes the fight out of thieves\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eOnGuard's Z-Cylinder is the lock's other line of defence. It's designed to resist the four most common attack methods: picking, pulling, drilling and bumping. Most bike thieves move on when a lock takes longer than 30 seconds — a cylinder that defeats their standard techniques is what makes that happen.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003e79cm of reach — frames and wheels, sorted\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eOnce unfolded, 79cm is enough to loop through your frame and both wheels and around a bike rack or solid post. That's the kind of reach a standard U-lock rarely offers. Out here where bike parking options can be limited, versatility in a lock matters.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eMounts to the bike, travels with you\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe included mounting bracket fits most standard bicycle tubes — top tube, down tube, seat tube — so the K9 travels on the bike rather than in a bag.

A cable lock can be cut with basic bolt cutters in seconds. The K9 uses hardened steel link plates — the same material approach as a U-lock — which resist cutting tools far more effectively. The Z-Cylinder also defeats the picking, bumping and drilling attacks that defeat standard locks. It's not indestructible, but it's a serious step up from any cable lock at a similar price.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eHow does it compare to a U-lock?\u003c\/strong\u003e\u003cbr\u003eThe K9 offers near U-lock levels of plate security with one key advantage: reach. At 79cm unfolded, it can loop through a frame, both wheels and around a rack in a way most U-locks can't manage. The trade-off is that a dedicated U-lock shackle is arguably slightly more resistant to leverage attacks — but for most real-world situations, the K9 covers what a U-lock can't.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWill it fit around both my wheels and frame?\u003c\/strong\u003e\u003cbr\u003eYes — 79cm is enough to secure your frame and both wheels to a bike rack or fixed post in a single pass. Useful wherever bike parking options are limited or awkward.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eHow does it attach to the bike for transport?\u003c\/strong\u003e\u003cbr\u003eThe included mounting bracket bolts to most standard bicycle tubes — top tube, down tube or seat tube. The folded K9 clips into the bracket securely, so it travels on the bike without rattling around in a bag or backpack.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eHow many keys does it come with?\u003c\/strong\u003e\u003cbr\u003eFour grip keys are included. Keep one on your keyring, stash one at home, one at work — you're covered if you ever lose one.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eIs it suitable for leaving a bike locked outside in Broome's heat?\u003c\/strong\u003e\u003cbr\u003eThe hardened steel construction handles heat and sun without issue. Like any lock, we'd recommend pairing it with a shaded or covered lock-up spot where possible — more to protect your bike's components than the lock itself.\u003c\/p\u003e","brand":"ONGUARD","offers":[{"title":"Default Title","offer_id":46385054974149,"sku":"7290001282137","price":99.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0730\/9928\/0581\/files\/K9Series-HeavyDutyLinkPlateLock-79cm.png?v=1781742710","url":"https:\/\/broomecycles.com.au\/products\/onguard-k9-heavy-duty-link-plate-bicycle-lock-79cm","provider":"Broome Cycles","version":"1.0","type":"link"}
