OKG High Security Chain - 4.3ft x 3/8 in. Thick Heavy Duty Chain - 130cm x 10mm Hardened Alloy Steel Chain - Premium Cut Proof Chain Ideal for Motorcycles, Generators, E-Bikes (No Lock)

Just received this chain and used it twice. I’m very impressed. Heavier duty than I was expecting. Purchased to secure my bike to my hitch mount rack. A casual thief wouldn’t touch it. A dedicated thief would likely cut the rack off the car before messing with this chain!

Excellent solution for securing a small motor & boat near the water's edge. I store my jon boat and 15HP Yamaha outboard near the water in my backyard. I sunk am 8ft auger at the rear of the boat and looped the chain through the auger head and then used an OKC stainless lock to secure the chain to the outboard. I really appreciate the corrosion resistance of the chain and stainless lock.

I’ve already own 2 security chains and locks for my eBike. First is the Kryptonite Forgetabouit Chain and Disc Lock Combo that is rated a 10 but it’s very heavy, about 15lbs. Opted out for a lighter option. And the second is the Docks Locks Security Chain that is lightweight. (I’ve already done an Amazon Review of the product) Now this product the OKG Security Chains is my third security chain that is in the middle of the 2 chains and probably my now everyday chain for my eBike. It’s a bit on the heavy side about 7lbs but provides the strength to secure your invest. This is the chain you probably want but you are limited to what kind of locks you can use with it since is not included. Which is a deal breaker for some. But you get what you pay for. Most padlocks and normal u-locks will work. I find that using a Kryptonite Evolution Mini Series 4 Disc Lock that is rated an 8 fits with the small chain link.You just have to trim off a portion of the protective casing of the U bar and you’re good to go! I personally recommend this lock.To sum this up. If you’re looking for a good security chain for your eBike or Motorcycle then I would look for the complete package. Both Chain and Lock. Top name brands are expensive but it is worth the investment. Or you can get this chain and then buy my recommended lock and you’ll still get it cheaper I think. You save money lol. That’s my review of this product.Thanks for the read!

This is a nice heavy duty chain - and it's heavy. We use it to wrap around a wheel of our trailer and to a post or to its axel. I do wish I would have gotten one a bit longer - this one works but it's a but tight for my needs. It comes in a nice little bag as well. The space inside the last link is large enough for some hefty locks. I paired mine with a "Master Lock M930XKADLH Magnum Heavy Duty" that you can find here on Amazon and they work well together. My only complaint is that I think it's a bit overpriced for the length, but if it keeps my trailer from getting borrowed then I'm all for it. I'll add a picture later - I forgot to take one.

It's a tough chain with a nice finish and the cloth disguise it .

Excellent heavy duty and thick. It could use another foot of length to work best for an ebike chain, but that’s on me for choosing this size

excellent chain! A bit heavy but thats whats its about, used for locking up our E-bikes with a top quality American made padlock

I got this to add additional secure points for group rides where we leave our bikes for a bit in a place we can't readily visit. It complements my Mastiff lock and chain. The OKC links are more narrow, but they do (just barely) make it over the lock (displacing the rubber covering a little). The nylon cover is decent. I do appreciate that the ends of the cover are secured together, but it does make it difficult to observe the quality of the welds in all of the links. It's a bit sturdy chain, it's not going to be light. It provides value for the money.
