Kryptonite Kryptolok 610 S Folding Bike Lock, 100cm Foldable Bicycle Lock

This lock is super cool and easy to use. You can securely lock your bike to irregular shaped and large diameter objects like light poles. If you’re locking up your bike in the community while you run into the store or stop for lunch, this lock is perfect. A casual bike thief with bolt cutters will likely move right along to another bike secured with a cable lock or lower quality u-lock. This lock is heavy… I zip tied the mount to the inside of my handlebar basket because I didn’t want to use the water bottle bosses on my frame. There’s so much weight over the front wheel though, that I have to be VERY careful parking my bike in the garage. The handlebars will turn and potentially cause the bike to tip over. This might be a consideration if you’re planning to stash this in a child’s bike basket.

Works really good just don’t get ur hands in between them when closing the will pinch your hands. Good lock tho I have it mounted to one water bottle holder good holder for lock too. Worth the money.

Expensive and heavy. Good if you are on an ebike. Otherwise, buy cheaper German version (a bit less in diameter, but 1/3 the price, an ⅛" thicker links, and lighter). Or buy 2 Expensive ones and leave them attached to your usual locking location(s).

seems very high quality and strong. takes a bit of practice to use these folding locks. the mount is solid, when mounted to the bottle holder mounts. the length of the lock is good.

BUYER BEWARE. We specifically ordered these locks for the coverage value. What is not said is the coverage COSTS MORE MONEY. After spending 20 minutes uploading the bill of sale, image of the bike, image of the invoice buying the lock (jpeg image only and 3 images under 10 MB what a PITA) I was led down the path of being ultimately charged $55 for anti theft protection for a lock that I thought I was getting insurance with. Never did I see that the anti theft offer is addition expense. That insurance offer was for only 2 years. And only for the 1 bike I was allowed to list with one lock. So.... if you think this is a good deal for the protection. It is not. With the TWO bike locks I paid for plus the added insurance for only 2 years, I was well over $250. Ouch.

Quality bike lock that stows away nicely. It is heavy but I expect that from a quality lock. Highly suggested based on ease of use and practicality

I use this to hit through my wheel and the body of my ebike and depending on the situation also through a bike rack. It's the perfect size, and since I am used to toting things on my ebike I don't notice the weight. I use this in conjunction with a Kryptonite chain lock and it feels very secure.

I am very happy with the ease of use, and how small it folds up to. Very convenient to have the holder attached to the bike frame.
