  • Compact and easy to carry, reasonable security, well designed mounting.
Color: Black
This is a standard-length bike lock for locking a bicycle. This length allows the front tire to be removed and set next to the bike and the lock looped through the front and rear wheel and around the seat tube and a pole. This secures both wheels and the frame. U-locks and most cable locks are designed for the same technique. Then flat plates are highly resistant to bolt cutters. The wide direction does not fit the jaw, and the flat area causes the contact area to be too high to cut. Not sure how it will fare against an angle grinder, but it is probably not any easier than any chain. The RC-50 hardness is usually a good balance between strength and brittleness. I assume that the engineers optimized this for the alloy used. There is probably a set of tools that could be devised to pry at the pivots, but this is probably not a normal thing. I am not a bike thief, and it has been a long time since I worked at a bike shop, so I am not up to date. What this type of lock does well is to be far more compact and easier to carry than cables, chains and u-locks. With the associated mounting, it is easily carried on the frame instead of in a backpack or on an awkward mount cantilevered mounting scheme. The bracket is designed to be mounted to standard water bottle mounts and has extra 'hose' clamps to support the extended length. With the lock inserted from the side, causes the rigid structure of the mount to absorb vibrations and shocks and to avoid stressing the elastic band used to retain it. In my use, this works well and is very quiet. It is a big improvement on my previous cable lock and significantly better than any u-lock I have seen. At least one reviewer worried about scratching the frame, but the plastic coating of the links seems to prevent this as well as making it relatively silent on rough roads. I prefer this type of lock because it is easy to carry and to deploy as long as you have a spare water bottle location. The mount is intelligently designed, and the lock is quiet while riding. There are a lot of somewhat similar designs that cost a lot less and a lot more. The really cheap ones are usually thinner and lighter. Similar sized ones seem to cost more, but performance information is difficult to come by. The price seems good to me. In the long run, all locks can be defeated. You need something that will delay the thief and be secure enough that the thieves go for a softer target. In most cases this should do the trick. ... show more

  • Sturdy Folding Bike Lock Provides Ample Security
Color: Orange-black
This OKG Security Grade Folding Bike Lock is very sturdy! I like the compact way it so efficiently folds up so that it is very compact! Hardened Steel, it weighs in at a little under 4 pounds, which might at first seem like a lot until you consider that the cable & lock versions that are decent strength weigh in at about the same, but take up more space. Nice product! ... show more

  • Very heavy
Color: Orange-black
I was surprised at how heavy this is. It feels very solid and is nice looking. The part to attach the bike to something is relatively short which means unless you can attach to a bike rack or have something else smallish you can get really close to this isn't for you. I need something with a longer piece that could say, go around a small tree or a larger post. For those who don't need this much length, this is great. It folds up to about 8x2 inches which is small enough to stash in a cargo bag. You will need to be careful about putting it with anything fragile because it weighs almost 4 lbs. and could easily crush anything lighter-in short-don't put in with your sunglasses! If this would meet your needs I definitely recommend it but I need to find something different. ... show more

  • Serious Security!
Color: Orange-gray
This is a seriously chunky bike lock. The lock is suitable if you have a high-end ride or even an old beach junker like mine. Construction is a series of hardened alloy steel sections daisy chained in series, designed to be anti-theft, anti-cut and anti-pry. The weight of the lock, in hand, inspires confidence. The lock ships with a plastic mounting cradle which can either be used with the mount holes typically on a bike's lower tube (hardware is supplied for this). If that option isn’t available to you, as is the case with me with my bracket holes used for a drink holder bracket, you can undermount the cradle on the bike’s upper frame tube. To use this method, heavy duty plastic zip-clamps are supplied. Rounding out the package are four keys, useful if you share use of a bike or even if you just keep losing keys. I had a small moment of confusion figuring out how to open the lock’s connecting piece but once I’d figured out that it slides out sideways from the lock (rather than pulling out etc.), things got easy. I also oiled the key slot as it felt a little dry on first use but that I consider a standard maintenance issue, especially if you live in a dry climate like me. Regarding that, I would caution not to lose that last key because I think you’d have a better chance chopping up your bike frame to get it free than breaking through this lock; it’s that substantial. The lock is heavy but, as long as you have it attached to the frame, that shouldn’t be a major issue. The packaging indicates you could even use this lock to secure a motorcycle and, having used it, I have little reason to doubt that. A great product and highly recommended by me. ... show more

  • Worth the money
Color: Orange-gray
I have an electric bike, and I use this lock for it. My bike is very expensive so I wanted a lock that could do the job. This lock does the job. I would recommend.
