But far from this giving me a feeling of helplessness or wondering ‘what’s the point?’ if they’re going to get it anyway I feel a renewed sense of determination. Naturally, I knew this before – I’ve seen enough videos of bikes being taken to have made this discovery. Security takes workĬhains can be defeated by angle grinders. Terrifyingly, I was through the smaller chain in around 30 seconds and the bigger in 1m 30s – albeit with the chain secured in a vice, which wouldn’t be the case for a thief and it would be harder with the chain looped around the bike and anchor with no slack left exposed to attack.

With my angle grinder technique improving, I set about a fairly portable 13mm chain and a chunkier 20mm version. They eventually settled on a fairly high carbon steel construction in various sizes. Image4 don’t manufacture chains but they conducted extensive tests on chain products from various markets – as their so-called ‘chain graveyard’ attests – in order to choose the ones they supply. The next logical place a thief would try to cut is the chain.

So, I think it’s safe to say that the Apex Pro is impervious to attack in a real-world setting with sparks flying and a screaming angle grinder in your hand in someone else’s garage. At this point, I struggled to imagine a thief fitting a fresh disc after 10 minutes of making a racket in a stranger’s garage, but in the interest of science I persevered.Ī third cut perpendicular to the first two still did nothing to the Apex’s structure and although a few hammer blows did now deform it, it would still be holding onto its prized motorcycle in a garage or lock-up. This took another five minutes and brought about the end of the first cutting disc – but had no effect whatsoever on the integrity of the ground anchor. The next most sensible cut seemed to me to be one parallel to the first. I didn’t expect this single cut to defeat the device but I’d failed to create even a modicum of give or flex so our bike was safe for now. I was pretty pleased with my efforts but dismayed to find that the Apex was standing its ground. Within around five minutes I’d made a pretty decent cut the length of the anchor’s tunnel which seemed like the most logical place to start. With my Scouts badge in metal destruction attained, I set about doing my worst to Image4’s Apex Pro ground anchor, which is rated Motorcycle Diamond in Sold Secure testing. I explained that I’d got no experience using an angle grinder, which I expected to be good news for them as I was about to set about cutting up their products.īut actually, what followed was a crash course in metal cutting and a few practice cuts on some scrap they had lying around. To find out, MCN headed to Image4 Security in the West Midlands – the people who design and build products including the Guardsman garage door defender and the Apex ground anchor.
