DVIC Bike Locks Heavy Duty for Anti Theft - 59 Inches - Bike Chain Lock with Chain Cutter Proof Fiber - Lightweight Bicycle Locks Patented Korea - Scooter Lock - Bike Lock Cable - Bike Security Cable

I was looking for a bike lock to fit into my small under-seat cargo bag that was light-weight and still leave me enough room for my mini flat-tire kit, wallet and cell phone. I got the longest Dvic lock and it all fits great with room to spare. I was surprised how light and compact it is. The locking mechanism is metal and seems well made. It couldn’t be easier to program your own combination and it’s long enough to go through both wheels and the frame (I highly recommend getting the longest one since it it so light and compact). The Velcro strap that holds it together for storage is very strong. I didn’t try the bolt cutter test on it so I can’t fully judge security. I only use the lock for locking my bike up to go into a store or restaurant while the bike is in a public place, so I hope this is enough of a deterrent. I am certain a U-lock is much more secure, but I didn’t want one of those heavy locks mounted to my frame and still have my quick-release wheels/tires begging to be stolen. If I went that route, I would still need to carry a heavy chain or cable.

It’s lightweight because it’s not some huge steel chain or metal cable but has tough strips of Kevlar inside that offer flexibility and lightweight while overcoming even battery grinders etc because it snags on the cutting wheel etc. it’s no $100 lock but for me it’s a great blend of security, weight, and cost!

The security provided by this lock is one of those things that’s only provable by testing it against cutters of various kinds. I don’t intend to try to destroy it to prove it’s going to keep my bike from being stolen. And I simply won’t use it in higher risk situations. But, for a quick and easy deterrent in easier situations it just might do the trick. As is, I think the Kevlar belt (instead of chain/cable) is more dependable than the simple barrel combination lock it’s attached to. The lock seems pretty light weight. In its favor is the light weight, non-stiff, and easily wrapped, easy to store and use attributes. There’s simply no reason to leave home without it.For serious situations I’d want a heavy weight chain and heavy lock setup. Or, even better, I’d avoid those areas entirely.

I wanted something small and lightweight but also sturdy. This fits in my shoulder bag without taking up much room and is easy to use. Great for when I make pitstops on the bike trail.

I noticed that they didn't put the material in which is probably armid Kevlar, other are cut resistant .The cut resistance is butter like and cylinders on the lock provide no secure security. I can't imagine the alloy holding up to a hammer. I would definitely use other locks because when you're riding, good lock your bike temporarily.

This lock is super lightweight, flexible, and easy to use in situations where you won't be leaving your bike alone for too long. So glad I bought it (though I wish I had bought the longer length - I'd suggest buying a size larger than what you think you'll need).

Very easy to store on the bike I combined two of them together to make it a 10 foot length because I have an electric tricycle and I wanted to pass through all three wheels and sometimes there’s an additional bike with me. Programming the lock code is very easy and —- Locking and unlocking is not difficultI can’t attest to its resistance because I don’t wanna destroy the product that’s mine but what I’ve seen online gives me comfort

I love how this lock is compact, light weight, and uses a combination. I would only use this for short bathroom breaks, or at a monitored bike valet, but for that kind of use case it is amazing. So light weight, able to fit in a small saddle bag along with your tools and patch kit, and you don’t have to worry about forgetting a key. I even threw it in my jersey pocket on a ride and forgot it was there, but in case I needed to stop to buy a drink or something, it would prevent a snatch an grab theft pretty well I think. The fact that I will probably always bring it with me means it will do a better job than any really heavy lock that I leave behind because I don’t want to bring the weight/bulk.Again, this is NOT for securing your bike in any sketchy places or for longer than a few minutes, it’s just for quick stops and discouraging any opportunistic thieves in secure locations.I got the 24" version and it just barely fits around a bike frame and a standard bike rack.Update: The mechanism used to set the combination feels a little cheap/weak, but so far, after 6 or 7 uses, it's still holding up. I still give this thing five stars.
