NDakter 5-Digit Heavy-Duty Combination Chain Bike Lock

Review

What’s included: a combination chain lock with a 5-digit resettable mechanism (default code set to 00000). Multiple length options are offered: 2.62 ft, 3.2 ft, 4.27 ft, 5 ft and 6 ft so you can choose the span that fits your needs.

Construction and materials: the chain is built from 0.24 inch alloy steel links for resistance to cutting and heavy wear. The lock cylinder uses zinc-alloy components and is designed to resist drilling and tampering. Around the chain is a woven polypropylene sleeve that guards against scratches, abrasions and exposure to heat or cold, helping protect your bike’s finish and extending the product’s lifespan.

Operation and security: the five-digit combination mechanism is user-changeable, providing 10,000 possible codes for personalized security. The mechanism is keyless, eliminating worries about lost keys. To use, simply wrap the chain around an immovable object and your frame or wheel, set your code and secure the shackle. Note: the 5 ft model weighs about 2.22 pounds; chain locks are versatile but can be bulky to carry.

Use cases and cautions: long enough to secure one to three bikes or to anchor a bike to posts, racks, gates and railings. It’s also suitable for motorcycles, scooters, skateboards, grills, ladders, doors and lawn equipment. While built to deter thieves and resist quick attacks, no lock is completely theft-proof—avoid leaving valuables unattended in high-risk areas.

Pros

  • 5-digit resettable combination for personalized security
  • Hardened 0.24 in alloy-steel chain resists cutting
  • Polypropylene sleeve protects bike paint and reduces wear

Cons

  • Heavier and bulkier than lightweight cable locks
  • Deterrent-level security — not invulnerable to determined thieves
  • Less convenient to carry for long rides without mounts

VerdictA robust, keyless chain lock that balances strong materials with practical use. The 5-digit resettable code and thick alloy links make it a solid deterrent for everyday security needs, while the fabric sleeve prevents frame damage. Not impenetrable, but a dependable, versatile option for securing bikes, scooters and similar gear.

Reviews

  1. Yvonne 5/5

    Perfect for our scooter

    Chose the red color for our son’s electric scooter. Feels well made, easy to set your own code and straightforward to use. Highly recommend.

  2. Jonny Easling 5/5

    Easy for kids to operate

    Bought for our children’s bikes and scooters — they can set and use the 5-digit code without losing keys. Sturdy build and easy to carry; fits our needs perfectly so far.

  3. Greg 5/5

    Well constructed

    Feels solid and heavier than expected, which I appreciate. Overall very pleased with the quality.

  4. Family Man 5/5

    Solid deterrent — gifted and used daily

    I bought this as a present and my friend uses it every day. The heavy steel links and five-digit combination make it much harder to defeat with basic tools. As a chain it wraps around objects easily and is very versatile. No lock is invincible, but this one feels built to deter.

  5. Meagan 5/5

    Keeps my scooter secure

    Has held up well and felt sturdy. Long enough to lock to most posts and not too bulky to toss in a bag. The code is simple to program and the locking action is smooth.

  6. Margarita Gonzalez 5/5

    Recommended

    I recommend this lock. It arrived on time and seems to be good quality.

  7. Tanya A. 5/5

    Good value and simple setup

    Five-digit code felt more secure than four digits and was easy to program. The fabric cover protects my frame and the chain reaches common racks and poles. Reliable for everyday locking.

  8. Filipe Vilaca 5/5

    Does the job

    Simple and effective. Locks up as expected.

  9. Tori V 4/5

    Solid build for storage use

    Picked this up for my son’s bike in storage. Feels heavy-duty and confidence-inspiring. It’s a bit bulky to carry daily, so I gave it four stars, but it’s perfect for securing a stored bike.

  10. Rational thinker. 1/5

    Video reviews made me nervous

    After watching clips showing a thief twisting the lock off and another where a child’s sibling broke it quickly, I hesitated to rely on it. I still take it on rides but I’m reluctant to leave a bike unattended.

  11. Miss T.V. 5/5

    Very sturdy and reassuring

    Sturdy design and user-friendly combination. Gives me peace of mind that my bike won’t be taken in a hurry.

  12. Pierre CHARLES 5/5

    Looks sturdy and effective

    Appears solid and performs its role as a deterrent. No need to worry about losing a key with the combination setup.

  13. André H. 5/5

    Good product — choose length wisely

    Good build quality. Be sure to select the proper chain length for your needs.
