OKG Heavy Duty Motorcycle Chain Lock, 4 Keys, 3.3 ft x 1/2 in (12mm) Thick Hexagonal Noose Security Chain with 18mm Cut Proof Hardened Alloy Steel U Lock for Motorcycles, E-Bikes, Mopeds, ATVs, Etc.

Got this lock for my wife’s bike and was very surprised to find out it is basically the same as the kryptonite New York cinch ring chain 1275 but at a fraction of the price. It seems to be made out of the same materials, has the same design, same features and same type of lock. I own the kryptonite cinch chained for my bike and if I could do it over again I would probably save my money and buy this one. I doubt there’s much of a difference and if there is I’m sure it’s not worth the price difference. This lock is a fantastic lock for the price if you can handle that #ChainLife

I love this bike lock. I have an electric bike that i like to take out to go get medicine and groceries, and on numerous occasions this lock had thwarted potential thefts of my bike and saved me money. It’s nice and hefty, and those manganese steel chains are quite durable. It’s long enough to easily lock my bike to bike racks and pole, and it’s portable enough to fit in my backpack.

The bike lock works well, and the addition of the 'noose link' makes it just long enough it to lock through the frame and both tires of my bike if the post isnt too thick. The lock is fairly heavy, but that is the point - it it weighed any less it would be compromising on security. Figuring out how to carry it took a bit of trial and error, but for me the best way to carry it was to loop it around my waist, though YMMV. I've also had some luck looping it around the crossbar on my bike, but it did shift around some while riding.The lock and chain came well packaged in some very nice foam, though with its construction it could probably have been thrown directly out of the plane and landed with just some scratches at my door.Other than the weight, my one nitpick about the device would be that the velcro that holds the fabric sheath on the links has a tendency to come loose. The sheath stays on decently well on its own, so it isnt an issue, but if you want the cleanest look then you might consider sewing the velcro tabs together since they shouldn't need to be removed often.

What a beast of a chain and lock. Can't be cut with anything less than a gas forth rig.

I like this chain/lock set very much. I’ve had my high-$ motorcycle chained to a steel post at my apartment complex for 8 months, and no one has messed with it. I’ve not had any issues with the lock, but it is under a cover, so doesn’t experience any moisture or icing conditions. I did notice that the weld on one of the links is a little questionable … hence the negation of one star. I’ll modify the review if any problems.

Very good bike chin and lock like the lil latch to prevent dirt or debri so it makes it easier to lock and unlock

This seems like very good quality. I was not able to use it though because it was not able to go around my hitch. There was a picture of a review on here where someone showed the shackle of the lock fitting perfectly around their trailer hitch end. This must have been a smaller trailer hitch because it came nowhere near able to fit around mine. Also the shackle was not quite long enough to snap the lock around the part that inserts into the trailer hitch although it can fit over the inserted section. I am returning.

I used this lock less than 5 times - on my 5th time, my key broke in the ULock. There was no incremental weather or other factors that could’ve contributed to the ULock issue. As this lock was chaining my stroller outside my house (and we have a newborn so needing this daily), it was a problem. There is no way to get into this lock or chain by civilian means.. I ended up calling a Locksmith who had to cut through the chains with a welder at a fine cost of $250. I contacted OKG on their website chat for options to help and they responded a few hours later that a Axlegrinder was an option to break the lock. No word on further support or refunds. I wouldn’t recommend this lock if you value getting access to the things you lock up. Compared to my kyptonite keys, the key that came with this lock was flimsy and I’m not surprised it snapped
