Bike security devices to beat bike rustlers

Oxford HD Chain from £45

Hardened steel chain with 10mm diameter square links. However, if you’d prefer something a bit beefier try Oxford’s Monster chain and padlock (£110) . The 1 metre HD chain weighs 2.6kg, so that’s just light enough to put in a backpack. There are other sizes, too: a 3.6kg 1.5 metre or 4.6kg 2 metre.

Abus Detecto 7000 £132

Disc lock with alarm, 100db plus your motionactivated choice of pretty designs. Feed it two AAA batteries, clip it onto a brake disc, and a beep will tell you the motion sensor is activated. The hardened steel construction is covered in plastic to reduce scratching. Order multiple locks at the same time and Abus can match them, so you only need one key.

Y Anchor £62

Cement the Y Anchor into place so it sits flush with the floor – 25cm from end to end. You then thread your chain through the top of the Y. Install it on hardcore and a drainage hole will keep the chain dry. 60mm box section steel construction with full seam welds. Securing multiple bikes? Choose the Y-max 90: 340mm end to end, and can take three 12mm chains at once. It’s £83.

Almax Immobiliser V £170

Almax claim their chains have never been beaten by a pair of bolt croppers. Their Series V chain is the ultimate for home use when twinned with the largest Y Anchor (Y-max 120, £128) or Almax’s own £80 Defiant anchor. Add a Squire SS80CS lock for £90. But it’s heavy: each link weighs over 1kg and the 1.6m chain weighs 16kg. The 2.1-metre option costs £240 and weighs 20kg.
