OKG High Security Chain Features
END NOOSE DESIGN
NOOSE CHAIN for effective loop-up design extends the chain FLEXIBILITY that enables the user to connect his/her cycle to another property or to an object which is connected with "the fixed world” (such as ground anchor, tree, fence, lamppost, etc.).
NYLON CHAIN SLEEVE
Durable, waterproof, weather-resistant, highly flexible nylon sleeve allows the security chain to be coiled compactly and covers the chain to prevent damage to the wheel or to the surface paint or coating of the valuables. Need nylon chain cover removable and washable, choose OKG 12mm style security chain (HOOP & LOOP velcro design at the end).
DEFENSE CUTTING TOOLS
10mm hexagonal sided links made of triple heat-treated boron MANGANESE ANTI-CORROSION STEEL for extreme strength, hardened throughout the entire thickness, rather than simply having a tough inner core or hardened outer coating. The narrower inner width of individual links prevents bolt cutters, hand grinders, and leverage attacks.
SOLD SECURE GOLD CERTIFIED
Sold Secure is dedicated to reducing the risk of crime by the assessment of security products through manual attack testing. OKG Products that have passed the evaluation assessed the coveted Sold Secure Approved quality mark.
Security lock chains from OKG are ideal to secure high-value items
OKG brand anti-theft chain is not easy to open with bottle jacks or lever tools difficult to cut with electric or hand tools. So, the negative reward for you enjoying huge security gains is: they are very heavy!!! Therefore, you must find the best balance between weight and safety before buying.
OKG MOTORCYCLE LOCK CHAIN uses the noose chain design to provide a more effective usage length. You don’t need to worry about the chain length when you select security chain because it can be used with most high security padlocks.
A BIT TOO HEAVY TO TAKE WITH YOU if you are riding a lightweight, expensive road bike, but maybe OK for an Ebike or gravel bike with a luggage rack.
Note: The locking shackle must be less than 14mm (9/16 in.) in diameter, otherwise it will not fit through the chain link.

USAGE TIPS
In order to crop a decent security chain, the thief will need to use one arm of the bolt cutter against the ground as leverage. The further your chain & lock is off the ground, the more difficult and less effective this will be.

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.

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

Well-made and the covering seems tough and is riveted in place. But the links are about 1mm too narrow to allow a 14mm u-lock, e.g. Kry Evolution, to fit. Disappointing, will have to return.

Ordered this chain to go with the Hiplok D1000 lock for my ebike. Unfortunately, it doesn't fit the Hiplok. It is a good quality chain. Regrettably, I have to return it.

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!

A very impressive chain that certainly provides some peace and mind when you walk away from your motorcycle.

Not impossible to cut with a grinder, but it would take a substantial time to cut through and be a 2 man job, time enough to scare them away.

This is best purchase I have made on Amazon. The chains are so heavy and tough, came with a lock that makes me stay at ease and sleep without having to worry about my bike

This is a wonderful motorcycle chain. Very strong and had enlarged loop at one end to self loop saving on length.

False advertising, advertised length is 5.3feet or 161cm. Now I have a useless chain.
