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.

  • Good lock for around town
Size: 4.27 feet Long, 6 mm Thick Color: Sky Blue
Sturdy, easy to use lock for my bike. The length is generally good although if it were a couple inches shorter or longer it would wrap around my seat stem perfectly. It wraps well, but I have to bring it down to the frame to take up slack when wrapping it when riding.

  • 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

  • Cable ok but thin chain
Size: 3.2 feet Long, 6 mm Thick Color: Black
The chain is much smaller than I anticipated - not thick at all. Other than that, I like the lock. Combination was easy to change and seems to work well. Covering on Size all good. I’m using this in conjunction with a ULock so I would never rely on this lock alone. I can see it would be easy to cut through quickly so it’s more of a deterrent. When I first wrapped it around my bike bar, I couldn’t get it tied enough, and it rattled a lot, and the chain noise was driving me nuts. It took a while for me to figure out how to wrap it and then adjust it after it’s closed to make it tight enough so it doesn’t jingle. I was able to do this, but it took some playing with it ... show more

  • Good quality lock
Size: 3.2 feet Long, 6 mm Thick Color: Black
I can confidently say I love this lock and hope to use it for decades. It’s good quality, a bit of weight to it. It’s worth a purchase especially for as long as you can probably keep it.

  • 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.

  • Perfect for locking up the golf cart
Size: 4.27 feet Long, 6 mm Thick Color: Black
We had another type of lock for our golf cart and it was always a twisted mess. Although it was fairly new, I found this one and we couldn’t be happier. It never kinks, is heavy duty and easy to lock.
