we have five angle grinder resistant locks that are currently available today so we are going to test them with an angle grinder and of course they’re all linked Down [Music] [Music] Below we’ have now concluded testing and we’re back in the studio so it’s time to go through what locks we tested how we tested them and what the results were to be clear the angle grinder test we carried out was over a period of 5 minutes of cutting time with the goal being to get in as far as possible while using a high powerered battery operated angle grinder the kind one may expect a thief to potentially use as you’ll find out some locks destroyed multiple cutting discs so in those cases we stopped the clock changed the discs and then carried on [Music] the light lock X3 is an angle grinder resistant lock and it is rated sold secure diamond for bicycles and ebikes now lightlock actually pioneered angle grinder resistant Tech with the X1 setting a trend that was followed by Brands like ongard Abus and hit block the features of the X3 are that it is claimed to be 20 times more resistant than a standard U lock and it’s said to be made with light locks proprietary bin ium material which is essentially a fusion of hardened steel and composite materials which is said to offer enhanced abrasion impact bending and twisting resistance it has a weight of 2.2 kilos and has a locking area of 195 square cm which puts both metrics as third best on test and it uses an abloy lock barrel for long-term key availability the lock itself comes with three keys so you should be pretty well covered it has a silicon lock cover and a neoprene sleeve for storage now when we were testing this lock it’s got to be said that it is actually very sturdy and there’s very minimal Play Between the locking mechanism and the shackle it has this soft touch Eco rubber coating which is great for frame protection and it also just gives it a really nice tactile feel when you look at the bottom of the lock here you can see that there’s some silicon which protects the keyhole which is great for keeping water and dirt and grime out of the locking mechanism however it can make finding the keyhole just that little bit trickier especially if you’re operating in the dark when it comes to mounting the lock though if you’re not someone who wants to carry this lock in a rock Sack or paner you can buy amount for it but it doesn’t come with the lock itself and does cost an additional 20 and it isn’t great for small frames but if you do have a larger sized bike it should be fine on to the angle grinder test and we could actually only cut a small way through into the X three in our 5 minutes of cutting time we burn through two discs and cut a third of the way through the lock the light lock was abrasive enough to wear down the discs but the angle grinder did manage to keep on cutting now this does differ to other locks which when you cut to a certain point the angle grinder would actually just kick [Music] back next up we’ve got the Abus Granite super extreme now this again is a so secure Diamond rated angle grinder resistant lock despite being pretty heavy and large though it’s not actually intended to be carried in a backpack or Carrier as Abus emphasizes its portability more than ease of Transport the lock itself uses wolf carbide which actually is just tungsten carbide the second hardest substance after diamonds for enhanced durability it has a 27 mm Square parabolic shackle with a locking area of 22 20 cm squared it weighs 2.1 kilos which is the second lightest on test 100 G lighter than the light lock and the lock Barrel itself is said to have a high resistance for picking and manipulation the lock comes with two keys which is the fewest out of all of the ones we tested but Replacements are easy to come by if you keep the code card when we were testing this lock it has to be said it also felt very solid and secure and there was no Play Between the shackle and the lock and it has a very satisfying click once it’s engaged I think the sheer size of this thing is actually a really good visual deterrent because it is chunkier than the others that we’ve got however the coating of this lock is a much harder plastic so probably won’t be as friendly to bike paintwork the extra locking reach of this lock is actually really handy if you’re running something with a bigger down tube like an ebike when it comes to mounting this lock the mount itself is actually very welld designed and it holds the lock very securely and it doesn’t rattle now it can be a bit fiddly to fit and it’s best suited for a paner rack but it can also be fitted between a chain stay and a seat stay in use this lock did perform very well but unfortunately the granite lost ground during our angle grinder test now we must stress that while the granite SE did not fail our angle grinder test it did show significant signs of lower performance compared to the others during our 5-minute test we only got through one disc and we were able to cut over just halfway through now if we extrapolate that out with potentially two cuts required to remove the lock the Abus would only need either two to four discs and around 20 minutes to remove it the Abus is clearly resistant to angle grinders however in a group test where all locks offer decent resistance to angle grinder attacks they must be ranked based on performance if you encountered a very determined or well equipped Thief with the time and patience the Abus clearly underperformed compared to the competition next up we have the hip loock dx1000 now hip loock is known for blending Style with security and it’s now tackling angle grinder resistance with this dx1000 like the other locks this is also a sold secure Diamond rated lock and it’s designed for bicycles with thicker tubes like ebikes and even motorbikes this lock features a square profile a graphine reinforced harden steel shackle and an anti- angle grinder security system the Locking area is even bigger than the previous two at 225 square cm it weighs in though at 2.7 kilos making it the heaviest lock in this test this lock has a pretty significant rubber to metal ratio and ultimately when you look at it from the outside you can’t actually tell where the rubber ends and the metal Starts Now the locking mechanism that is inside here is reported to not have any pick since it was debuted back in 2021 which I’ve got to say if true is a pretty decent reputation to have when we start to think about how much this lock actually costs in the UK it’s £300 and over in the states it’s $350 I’ve got to say it almost feels a little bit underwhelming due to the noticeable Play Between the shackle and the lock although hit block have confirmed that this won’t affect security the lock heft has made it cumbersome and it is tough to transport without a proper mounting system and it does require storage in a paner or a backpack but that does ultimately then take up a lot of space hit blocks rubber flap that covers the Locking System is simpler than competitors and offers better visibility and easier key engagement especially when you’re bent over a bike crack in the dark while the dx1000 didn’t really stand out during usage it also didn’t actually cause any issues that changed though when it came to the angle grinder test as it stepped up and performed seriously well as it heavily resisted our attacks we applied considerable Force when we tried to cut into this lock but ultimately it was The Cutting disc which suffered as it quickly showed signs of wear holding the grinder steady proved difficult when trying to reach the center of this lock which appears to be a part of hip locks anti- angle grinder security system each time we attempted to reposition the cutting wheel the cause material kicked the grinder back we managed to burn through two discs in our 5minute test but there was no way we would have been able to cut any further through the lock due to the [Music] kickback next up we have the ongard Rock Solid 8580 now you might not have heard of ongard but it is a subsidiary of Magnum locks which specializes in security this again of course comes with a soul secure Diamond rating and it’s designed to resist angle grinders it has a 15 mm harden steel shackle with a patented Rock Solid finish it has a 1.3 kilo weight making it the lightest in its class but it does have a smaller locking reach it has an x4p Quattro 4o Locking System a z cylinder lock Barrel resistant to picking pulling and drilling it includes five Keys which is the highest am all of the angle grinder resistant locks that we’ve had on test and the automatic key cover and rubberized coating do offer really good durability and weather protection we think that it’s got a really good quality feel with that soft rubberized coating and minimal shackle play there is a slight bit of difficulty when it comes to aligning the lock when removing or engaging however if you just slow down take your time you will get there in the end it has a smooth and consistent key operation once engame Ed but the weather guard can be just a little bit tricky the smaller locking reach may be tricky for crowded areas like transport hubs but I don’t think it will be an issue for less busy locations the angle grinder test is where the ONG guard Rock Solid really sha it was by pure coincidence that the ONG guard was the last to be cut and its resilience took all of us by surprise during our 5minute test the on guard barely showed a scratch the patented Rock Solid coating that’s been been applied to the 15 mm harden steel shackle effectively sanded down the cutting disc launching plumes of grinded disc dust into the air in well under the 5- minute time limit we burn through three grinder discs which is the most of any lock on test it was taking about 30 to 40 seconds for a disc to essentially evaporate into thin air and when you look at it now obviously forgetting that big hole in the rubber coating there’d be nothing to stop you from using this again and barely made a [Music] mark The Squire stronghold D16 Max is a UK made bike clock with a sold secure Diamond rating costing £ 28999 P however its design has notable drawbacks that hinder usability and undermine its appeal the Lock’s plastic cover feels flimsy diminishing trust in the product’s durability additionally the lock body and shackle exhibit no noticeable play although this doesn’t affect security despite its generous 209 cm square locking area the thick rubber ice coating makes securing a bike fairly cumbersome weighing 2.7 kilos it is one of the heaviest locks on test and given its price point the stronghold D16 Max faces stiff competition from Superior options like the hip block dx1000 which offers better reach security and a similar weight for just10 more now on to conclusions and my overall verdict on all of these locks we’re going to start with the Abus at 260 or $320 the granite super extreme 2500 is the third most expensive on this test however considering that it includes the superb Mount and the lightlock X3 requires an additional purchase the Abus represents decent value while there is some Nuance in how well the locks perform du doing the anle grinder test the lightlock X3 does outperform it which means the Abus slips into fourth overall for many Abus is a known entity and the quality of the Granite SE is second to none so if you like to travel light and keep the weight on the bike and not on you there is absolutely no reason not to choose the Abus Granite super extreme at £300 or $350 the hip loock dx1000 is not only the most expensive lock in this test but it’s also the most expensive lock we have tested here at cycling weekly for this cost we expected it to stand out from the crowd and be the best but the dx1000 does almost the opposite it’s understated and functional and just gets the job done now while this isn’t a bad thing the DX 1000’s extra weight and the fact that it is 100 more expensive than our overall winner starts to make the hip blck look like poor value that being said its performance in the angle grinder test was impressive and provided hit blocks claims surrounding their unpickable lock cylinder standup the dx1000 offers a very high level of security for your bike with such a performance the hip block secure third place now if it weren’t for the exceptional performance of the ONG guard Rock Solid in the ankle grinder test the light lock might have easily secured the top position although there is a minor difference of price of £50 or $50 between them the extra reach and features diminish this disparity for those who need them the extra expense of the Tactical Mount brings the x3’s price closer to that of the Abus Granite nevertheless its performance in the angle grinder test and overall quality surpasses competition from either Abus or hip blck and lastly given the sheer amount of security that the ONG guard Rock solid offers against angle grinder attacks you may be surprised to learn it’s the cheapest on test at £200 or $250 that’s £50 or $50 less than the next cheapest the lightlock X3 and a massive 00 or $100 cheaper than the hiplock dx1000 while we are rewarding the ONG guard the title of best overall angle grinder resistant lock it could also be best budget most secure and most user friendly this shouldn’t reflect badly on the other locks in the test though as they all performed well none failed the angle grinder test and all offer similar specs and retail prices but the onguard Rock Solid stood out in a field of outstanding performances having that little extra something to give
