Security & Durability
Security is the most important feature when you look for a bike lock. The NDakter Bike Chain Lock offers a 5-digit resettable combination, which is much safer than the usual 4-digit locks I’ve used.
You can set your own personalized number easily, and with 10,000 possible combinations, cracking the code is nearly impossible. The lock cylinder is made of zinc alloy, making it very hard to break or drill through.
What really impressed me is the chain itself, made from 0.16-inch thick alloy steel that’s resistant to drills and other tampering. I also noticed the lock has a scratch-proof fabric protection wrapped in high-quality polypropylene fabric that protects your bike’s paint and frame, which is great because I hate when locks scratch my bike tires or frame.
When I used it outdoors, even in harsh weather, the lock held up well without rust or wear, thanks to its polished finish and durable materials. It’s heavy duty but still portable enough for everyday use.
Security Features
The NDakter Bike Chain Lock uses anti-theft technologies like a drill-resistant alloy steel chain and a zinc alloy lock cylinder. These features greatly enhance security by resisting common attacks like drilling or cutting attempts. I feel confident locking my bike, scooter, or even my grill outside without worry.
Materials and Construction
The chain material is thick alloy steel available in 4mm and 6mm options, which is strong enough to resist bolt cutters. The lock body is zinc alloy, adding corrosion resistance and durability. Plus, the whole chain is wrapped in polypropylene fabric that protects your bike and your hands from hot or cold metal in extreme weather.
Ease of Use & Portability
Using the NDakter Bike Chain Lock is simple. There’s no key to carry around because it uses a 5-digit combination code. I set my own code easily and reset it whenever I want.
The lock head diameter fits most bike wheels with a gap of 1.25 inches or more, which covers almost every bike frame and bike seat I’ve tried it on.
Carrying the lock is easy since it’s lightweight (just about 0.71 pounds for the 2.62-foot version), and it fits nicely in my bike bags without taking much space.
The lock is long enough to secure one or two bikes together or attach to a fixed object like a fence or gate.

The chain-link design is classic but wrapped in soft fabric, making it safe for your bike’s surface. Inside the box, you get the chain lock ready to use with the default code 00000, which you can reset anytime.
The lock uses a hand control mechanism with a touch control method, making it easy to operate even when wearing bike gloves or after a long ride. I appreciate that this lock combines security and convenience without bulky keys or complicated installation.
Specific Aspects
Weather resistance is another strong point. Whether it’s raining or freezing cold, the NDakter Bike Chain Lock stays reliable thanks to its protective coatings and zinc alloy lock body. This makes it suitable for daily riders and commuters who face all kinds of conditions.
