NDakter Bike Lock, 5 Digit Combination Heavy Duty Anti Theft Bicycle Chain Lock, 2.62/3.2/4.27/5/6Ft Long, High Security Resettable, Suitable for Bike, Scooter, Door, Gate, Fence-4/6mm Thick

I’ve been using the NDakter Bike Chain Lock for a few weeks now, and I’m extremely satisfied with the quality and peace of mind it provides. The chain is thick, heavy-duty, and clearly built to deter theft — it feels much more robust than the cheap cable locks I’ve used in the past. The 5-digit combination is a big plus — more secure than the typical 4-digit ones, and easy to set/reset. The mechanism works smoothly without sticking, and it gives a satisfying “click” when it locks into place. At 3.2 feet, the length is perfect for locking my frame and rear wheel to a bike rack or post, and the protective fabric sleeve keeps the chain from scratching my bike’s paint. I've used it in both dry and rainy weather, and it's held up great without rust or stiffness. For the price, you’re getting a tough, well-made lock that’s easy to carry in a bag or wrap around the seat post. Whether you're commuting or just parking your bike around town, this is an excellent choice. Would definitely buy again and recommend to friends!

This bike chain is great. Well made. Quality material surrounding chain. Easy to set the combination lock. The covering makes it quite on the bike. I bought it instead of cable locks I have had before. They are easier for crooks to cut through.

I am updating this review and switching it to 5-stars. Their customer service responded quickly to an issue I had with the lock and even sent out a replacement with next day delivery. The new lock works great. These are very easy to set the personalized combination. This comes with a color instruction sheet packaged with the lock inside the box and the instructions are also printed on the bottom exterior of the box. The chain is wrapped in a nice flexible nylon casing that protects my bike frame from being scratched by the chain. I like the 5 digit combination as it make this lock more secure over the 4 digits other locks on the market. As I mentioned, setting the combination is very easy. The biggest plus for this lock beyond what it is intended for, is their customer service.

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.

I picked up this 5-digit bike chain lock for my son’s bike, which we keep in a storage closet, and so far it’s been a great choice. The lock feels heavy-duty and well-made, giving me confidence that it will hold up against tampering. The chain itself has a nice weight to it, and the 5-digit combo adds an extra layer of security compared to the standard 4-digit locks. The only reason I’m giving it 4 stars instead of 5 is that it’s a bit bulky, which makes it less convenient to carry around if you were using it daily. But for our needs, keeping a bike secured in storage, it works perfectly and gives me peace of mind

Great Bike lock, solid, good tumblers, and secure. Better than expected. Hefty!

Works super well, easy to use, and is overall just impressive.

Solid buy

Very sturdy structure and easy to use combination lock. Gives me peace of mind to know you can't cut through the chain in a hurry, nor break the lock easily. My bike will stay locked to whichever rail/lamp post I choose :D

Does the job

Attention de choisir la bonne longueur.

Great buy!!

Fun and when set up easy to use
