- Weatherproof & Strong Protection Our chain lock is made of durable 3T manganese steel. The 10mm high-strength square-link chain is thick enough to withstand 6KN tension and 13KN shear force. The anti-theft lock cylinder and rotating switch help prevent technical opening, rain, dust, and other intrusions, making it suitable for year-round outdoor use.
- Heavy-Duty Materials & Safety Non-toxic PVC material, sturdy ABS material, and a reinforced rust-resistant alloy steel chain meet EU environmental standards. The nylon sleeve provides additional protection and helps prevent scratches on your property. The 16mm U lock uses a hard zinc alloy shackle with a thick PVC coating, resisting cutting, breaking, sawing, and shearing.
- Four Keys & Replacement Service Comes with a sturdy disc lock made of a 16mm hard zinc alloy shackle and thick PVC coating. Resistant to cutting, breaking, sawing, and shearing. Includes 4 individual ergonomic keys (one with LED light), made with a stainless steel lock core that is designed not to bend or twist easily. Replacement keys are available upon request.

Heavy duty
Size: 4ft/120cm x 10mm Diameter Chain with Lock
Very heavy - works well for our 2 E-bikes. Very secure. Highly recommend.

Now this is a bike lock!
Size: 4ft/120cm x 10mm Diameter Chain with Lock
Chain is very heavy, with flat links and a durable cover and the lock looks like it would survive a nuclear explosion, and it has a neat security feature, so if someone got your keys, they probably wouldn't be able to open it, unless they knew the secret. Excellent security, highly recommend it!

Sturdy, not too portable
Size: 4ft/120cm x 10mm Diameter Chain with Lock
This bike chain does what it says, with high quality steel and a recessed lock to resist drilling. But it is heavy, over 6 pounds, too heavy for me to comfortably carry on my bike rides. I recommend it as a good home bike lock, but something else is needed for securing the bike while out and about.

I've had such a streak of bad luck on Amazon lately, I'm ready to give up on it. That is until I purchased this bad boy. It works exactly as advertised and is in much better condition/quality than I had anticipated. Very happy (for once) to make a purchase from amazon

Heavyweight chain
Size: 4ft/120cm x 10mm Diameter Chain with Lock
I like the sturdiness of the chain but I’m not crazy about the locking mechanism. Whenever you unlock the bike in order to remove the key from the cylinder you have to close the cylinder back up to remove the key which is an inconvenience because next time you want to lock the bike you have to hold both ends of the heavy chain in one hand and insert the key into the locked cylinder and open it up before you can insert the large U-shaped clamp holding the chain into the cylinder. The lock should’ve been made so the key can be removed with the cylinder in the open position to make it easier to relock the bike.
