NDakter Bike Chain Lock, 5 Digit Combination Heavy Duty Anti Theft Bicycle Chain Lock,2.62/3.2/4.27/5/6Ft Long Security Resettable Bike Locks for Bike, Bicycle, Scooter, Door, Gate, Fence-4/6mm Thick

I'm not sure whether this lock would deter a really determined bicycle thief, but it's certainly more than enough to prevent some casual ne'er-do-well from swiping your ride. Both the chain and lock seem *very* heavy duty and the nylon sheath covering the chain offers near-total protection for your bike's finish.The locking mechanism and combination tumblers work very smoothly and the numbers are bright and easy to see in most lighting situations.My eBike, which is what I bought this for, is on the pricey side, so I use this lock in conjunction with a "horseshoe" type lock and a folding lock. I've also installed an alarm on my bike. Even so, I rarely leave the bike alone in an area that doesn't have security cameras and a lot of foot traffic.

Sturdy yet lightweight chain lock. It took me a while to come up with a 5 digit combo, but that's another level of security. I feel very safe securing my bike with this lock. It also fits into my little frame pouch, which is a nice bonus.My only regret is not getting a longer lock so I can wrap both wheels and frame into it.

The shortest size lock is perfect to go around stand of a e-scooter but it still does not get in the way of the wheel and just be long enough to hook to different things around town. It’s safe, affordable, and easy to set the combination and with it being the perfect size, I have zero regrets bring is lock.

Get it. I've had bikes stolen in the past, so I wanted a heavy-duty lock. This lock is long enough to weave through the frame and wheels and is very durable. The combo setup is easy to use and great for locking up your bike quickly.

It's a good lock, the combination is easy to set and I like the color. My only complaint is it's not 4.27 feet long. I measured 48" from end to end which is barely longer than my old chain. The whole reason I bought it was to have a longer chain which is frustrating but it's still a good product.

A lock only stops an honest man, but i don’t have any complaints about the quality. its real chain and doesn’t scratch your bike. I have a mountain bike so it wouldn’t bother me but some folks with nice road or gravel bikes probably would

Using this to lock up my trash and recycling bins in NYC. Works well, easy to use, seems secure.

The lock is exactly as described. It is easy to use and set the new password.
