Features

  • SECURE & RESETTABLE: 5-digit resettable combination bike chain lock, much safer than other 4 digit locks. Easy to set your own personalized number combination.
  • STURDY & DURABLE: It's hard to break through as the lock cylinder of the bike lock is made of zinc alloy. The bicycle chain lock is made of 0.24 inch alloy steel which is drill-resistant and anti-tech unlocking.Safety tip: Please do not leave your bike out of your sight for too long, especially in high crime areas, no bike lock is 100% safe.
  • 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.
  • CONVENIENT TO USE: Combination locking mechanism provide keyless convenience and set your own password by easy steps. With keyless convenience lock, you dont worry about lost the key and forget to carry it.Code design saves you from the hassle of carrying keys. The code is resettable - there are 10,000 combinations you can set, which makes the chances to crack the code only 1/10,0000. The default code is 00000.
  • MULTI-PURPOSE: The chain lock is 4.27 feet and weighs about 1.87 pounds, long enough to lock 2-3 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.

  • Secure, and sturdy
Size: 3.2 feet Long, 6 mm Thick Color: Black
Was a great value works great for my bike and bike rack. Instructions on how to set the combination. We’re very clear and easy to use strongly recommend this.

  • Great product, simple but efficient
Size: 3.2 feet Long, 6 mm Thick Color: Black
The secure lock looks very solid, the tumblers rotate nicely and feel solid. The chain concept is simple but efficient, easily wraps around a tube and is quickly set.

  • Great material, good weight behind it
Size: 3.2 feet Long, 6 mm Thick Color: Black
I like this thing, it is just as described and will work perfectly fine. The combination was easy to change and the turn dials work well, nice and smooth. As usual with these types of chains they store well and are portable by just wrapping it around the top bar. It is long enough to go through the front wheel, the main bar, and around a bike rack. I would hope this thing comes in handy. I would recommend this, especially for what it costs, it is well worth the security and peace of mind it brings. ... show more

  • Great lock and pretty too!
Size: 4.27 feet Long, 6 mm Thick Color: Green
Got 2 of these one in green, one in blue. Both are not only functional but nice looking and I like the colors. Was very easy to set combination to the lock and then use. Would recommend to anyone.

  • Quick and easy to use for quick stops.
Size: 3.2 feet Long, 6 mm Thick Color: Orange
Although no lock is thief proof even the expensive high end D Locks. That being said not all situations can call for a D Lock. Some stops may present a challenge finding a spot to hook a lock to. Just protecting the frame and back tire means the bike can be lifted and carried off or thrown in a car or truck. This chain gives a little more length to wrap around a thicker pole or tree. I have a thick cable if I need extra length and a FoldyLock which is shorter than this lock but stronger. This is great for the quick stop no key run in run out and park where visible. Convent and quick. Most experts say spend 10% of bikes value on lock. If your bike or e-bike is expensive get insurance and use 2 or 3 locks to make your bike to much trouble to steal. Get a cheaper bike as a backup & lock. ... show more

This chain is thick and heavy! Well made and the combination lock is not crackable.

  • Nice bike lock
Size: 3.2 feet Long, 6 mm Thick Color: Camouflage
We like this one compared to our other rubber one because it doesn’t freeze in cold weather. It’s easy to position and I like that it’s a combo lock vs. a key. It is heavy and doesn’t wrap around my kids bike as nice as the smaller rubber one, but it’s definitely easier to use. The camp print is fun for my son as well. ... show more
