UBULLOX Bike Chain Lock 3FT 5-Digit Combination Bike Locks Anti-Theft Bicycle Lock 6mm Thick Resettable Steel Chain for Bicycle, Motorcycle, Scooter, Gate, Fence

Very strong and functional. It's about a foot and a half long, and 2 inches thick with a completely metal inside. There's no cutting through it, or forcing it apart, the lock is very strong.

The instructions were clear and the set up was quick and easy. Seems sturdy enough and the cord is wrapped to limit damage to the paint on the bikes. Simple to lock and unlock.

Love it because it is very sturdy and strong and flexible. Easy to set my own lock combination. So far the chain has been long enough to lock my bike to a rack

good

Bought this lock a year or two ago. I have been using it for a long time and I feel confident in locking up my very expensive e-bikes and leaving them. It’s a heavy and bulky item but I use saddle bags on my bike and carry it in it! You are foolish to skimp on your lock. The length is appropriate. I endorse buying this product.

Great product!

works great, a good price and I think impossible to cut with tools thieves might have. Highly recommend the longer one even though a lot to drag around you can ensure you can lock the frame and the tires.

these locks work great!! easy to read for older people and easy to use as well. we have to lock our bikes up at every stop in key west and we could not be happier with how easy these locks are to use!! Highly recommend!!
