Really sturdy lock. Missing the mount though?
4 out of 5 stars
Really sturdy lock. Missing the mount though?
The 16mm really makes this thing like a tank. The way this thing locks inside is with 2 bolts on both sides (see pic). The U itself is very sturdy. I tried bending it but doesn't move. A nice feature is that the silver part can twist to cover the key hole. One thing i believe though is that the locking mechanism is sensitive to dust/debris, which was why some of the reviewers had theirs stuck. On the key tags, it even says to clean and lubricate regularly with a lubricant such as wd-40. Of course this is with the laser cut keys being so thin. Thats why they give you 5. haha. Another thing, when you unlock the lock, you can't pull out the key until you've lock it back. A way to make sure you've locked your bike i guess. And to make sure you know what you are buying, this lock does not come with a bike mount. You'll have to buy one/ make your own, which is kind of a bummer. If you search youtube for bicycle u lock mount, there's a vid of a homemade one. I made one out of it too :)

    5.0 out of 5 stars It really is a brute.
    Reviewed in the United States on February 21, 2010

    After getting a bike stolen, I started looking for some decent U-locks. Since I sometimes lock up two mountain bikes at a time, I needed one with a long shackle. The two best on the market are the Kryptonite New York LS, and the OnGuard Brute LS. The Brute is considerably cheaper, so I decided on the Brute.

    As other reviewers have noted, the new, improved version I received differs from the photos on Amazon. I also noticed that the packaging markets this lock to motorcycle/scooter users, not to bicycle users. As a result, no bicycle frame mount was included. I've read reports of OnGuard's bike mount being flimsy and quickly breaking, so the lack of their mount is no big loss. I have a few TwoFish LockBlocks and BikeBlocks that I can use instead, and they are very durable solid rubber mounts.

    OnGuard sure likes to give you plenty of extra keys. There is one rather large lighted key and four spares. The lighted key seems more of a gimmick, so I just carry one of the smaller spares on my keyring. Even that was a bit bulky so I cut the key's head down to a small arrowhead shape, following the molded lines in the plastic. Even if you somehow lose all five keys, you're still not out of luck. If you register the lock with OnGuard, you can always order more keys in the future.

    The anti-theft insurance offer sounds like a good idea, but if you read all the fine print you'll discover there are enough loopholes to get OnGuard out of paying for most anything. No matter, I didn't buy it for its insurance policy, I bought it for its theft deterrence ability.

    The lock itself is very hefty, weighing over five pounds. The shackle is 16.8mm thick, slightly better than the old version's (and Krypto's NY-LS) 16mm shackle. I had an old KryptoSTD lock and I could slightly bend the shackle because it was not hardened steel. I could not bend the Brute's hardened shackle AT ALL. Anyone who tries to cut this with a hacksaw or bolt cutters would get exhausted and give up. It may not stop a determined thief with an angle grinder (no lock can), but it will at least put up a good fight.

    2.0 out of 5 stars You won't get your bike stolen
    Reviewed in the United States on October 6, 2011

    After a lot of consideration, I gave this U-Lock a 2-star rating.

    Since I got the lock, I've had some problems unlocking/locking it with the keys provided. The lock starts to "stick". It's as if something isn't aligned properly. This went on, and got slowly more severe, until I couldn't turn the key at all. I ended up having to call the police to come take a saw to it so that I could get my bike off of the rack. Here is a picture of the lock afterwards: (...)When talking to the police, they mentioned that they had this happen to three of these same exact locks this week alone. So this is not an uncommon occurrence. That is why I'm giving it two stars.

    However, they also said that it was the hardest lock they've ever had to cut through. Believe me, nobody is getting through this lock. They had to get out some heavy machinery. If someone is willing to go through that much effort to get to your bike, then no lock is going to save you. I just wish they would fix the locking mechanism. This would be elevated to the perfect lock.

    Even though Amazon is shipping me a replacement for free, I'm probably going to invest in another lock as well. Just in case.

    3.0 out of 5 stars So %$&^ing heavy and awkward!
    Reviewed in the United States on December 6, 2011

    Like you're probably doing now, I read a lot of the reviews that mentioned the weight of this thing and how big it was and didn't really care because I wanted a great lock. Not to beat a dead horse or anything, but it is so freaking heavy and awkward! It does exactly what it is supposed to, and I'm pretty sure you'd need a cutting torch to break through this thing, but it is a giant hassle to transport when not in use. I have a Crosstrail by Specialized and this lock won't fit anywhere on the bike, including the cross section where you normally store a lock. I would really recommend checking one of these out at your local bike shop and getting a feel for it before you purchase one online.
