- SCRATCH-PROOF FABRIC PROTECTION: The bicycle chain lock is wrapped by a high quality polypropylene fabric, which is scratch-proof and wear-resistant, anti-hot and anti-icing hands; it protects the chain and prevents it scratching your bicycle frame, long lifespan.

- MULTI-PURPOSE: The chain lock is 4.27 feet and weighs about 1.87 pounds, long enough to lock 1-3 bikes together, or lock your bike to a tree, gate, fence, railing, thick pole and others. The lock can also be used for motorcycles, scooters, skateboards, grills, ladders, doors, lawnmowers and many others.
- KINDLY REMINDER:The lock head's diameter is around 1.25"/3.2 cm, satisfying the security demand of nearly all kinds of bike wheels currently on sale. Nevertheless, if you have Scooter, e-bike or any thing with wheel gap/hole less than 1.25"/3.2 cm, the lock will not be able to pass through the wheel. In this case, we kindly suggest that you may lock the scooter by wrapping around it rather than passing through the wheel gap.

I like it. I was pleasantly surprised when I learned that I can set my own combination and how easy it is to execute. The lock in and of itself seems rather sturdy, no one is cutting this one with mere wire cutters. I also like how this one is a combination lock as opposed to a key so now I can allow my trusted coworkers to utilize the lock even when I'm not present.

This bike lock works great! It's sturdy, secure, and gives me peace of mind when I’m out and about. The combination dial is easy to use, and it’s much more convenient than dealing with keys. One important tip: Don’t forget your combination! There’s no way to reset it, so once it's set, write it down or store it somewhere safe. Otherwise, you’ll be shopping for bolt cutters.

This chain lock is very heavy duty (and heavy). The combination is easy to set or change. The numbers on the combination lock are easy to see (good size white numbers on black background). The covering over the chain appears to be sturdy. I use these locks to secure ladder(s) to a boat cradle from fall to spring so they live outdoors 8 months each year. Will post an update if this lock fails its first winter.

The media could not be loaded. I love to cycle but I am always paranoid that I can't leave my bike unattended even if it's to make a quick stop to go to the bathroom. I have been shopping for a bike lock for quite some time and feel like after a lot of research I have found the best one. The NDakter Bike Chain Lock is not only one that is super easy to program your code but also one that feels very sturdy which features an external cloth covering which goes over the metal chain to make it harder for someone to try to cut it off and run off with your bike. The other things I really like about this product is that it comes in many different colors and 2 different lenth formats. There is a shorter one and I went with the larger one thinking ahead for if I am biking with my girlfriend or someone else we would be able to lock both bikes onto a bike stand and protect both of them from theft. The color varieties are almost endless, I went with the black to make it simple but I could have easily gone with one of the blues or reds. The last thing that I wanted to mention is that there is one drawback for some folks who are looking for a very lightweight bike lock. This is not the lightest bike lock and wanted to make a point to inform everyone, especially to those road cyclists like myself who are always trying to shed grams to be able to go faster on the bike. The weight component doesn't bother me especially because I know that it is because it is made really well and will do the job that I am wanting it do which is to protect my bike from theft. I highly recommend this product for those looking for a durable and easy to use and program bike lock.

Had to find an alternative to lock my French Door Fridge bc my young grandchildren were getting in it and playing around with the food. If they were eating the stuff they took out I’d be fine with it but they weren’t. The supposed child safety lock I initially got worked for awhile then they figured that out. This worked like a charm. I have a security camera in my kitchen and watching them trying to figure this out was hilarious!

Inexpensive, easy to use, and light weight. As expected this cheap lock doesn't give much protection. A bike thief was able to snap the metal rod that connects both ends of the chain when it is locked. This happened in broad daylight on a major street with people around, so it wasn't necessary to use an angle grinder to break this lock.
