Folding Bike Lock with Mounting Bracket Bicycle Locks Anti Theft with 360° Rotating Lock Head Waterproof and Scratch Resistant Foldable Bike Chain Lock

I mounted this to the bottle bosses on the underside of my bike, it's completely out of the way until you need to use it. The purple elastic strap is easy to use and the lock stays secure and doesn't make any noise while riding. The lock can be deployed or put away in under a minute.The protective coating is very thin, not rubberized, and I don't think it's going to be very kind to the mediocre paint on my frame. I'll have to be careful.It came with some oversized zip ties if you want a more custom installation location, but fortunately my bike had these unused bottle bosses ready to go.

This is an unusual bike lock, but it works well. It folds/unfolds easily but not too easily. You can definitely feel the weight of the weight of the metal behind it. The anti-scratch coating is quite thick - you can see where the coating stops around the rivets. It is so think, in fact, it makes me kind of wonder how thick the metal plate behind it is. The lock comes with mounting screws for the bottle holder and with heavy duty plastic straps with tightening screws that you can mount pretty much anywhere. My water bottle holder is already taken, so I ended up mounting it on a seat post part of the frame without any issues. Overall it works great. My only worry is how well the rivets will hold up if someone is trying to knock them out with a hammer or some such. Not something I'm planning on trying myself, however.

I wasn't exactly sure what to expect when I chose this lock. I find the chain locks unwieldy and heavy. Wrapping them around the seat or keeping it in a saddle bag isn't a great option. When I saw this, the idea of a modern looking, all metal lock that folds up and attaches to the bike frame was intriguing.It arrives packaged well, and works like a dream. My only complaint is there are no instructions on how it works or how to mount it properly. While it didn't take too much time to figure it out, a "quick start guide" would have made my initial impression much better.All in all, a good lock.

I like the strong, heavy-duty metal. I believe the flexible device style will prevent theft. I like that it has bolts and screws, and keys for secure action. I would at least warn, that until it is practiced indoors, the lock set up is not swift like a typical padlock. I used this indoors within safe confines, practicing timing and technique. You can’t be too careful.

This is a great alternative to more expensive name-brand folding lock. It weighs only ~14.7oz (417g) and small size that fits nice in one hand. Instead of mounting on my bike frame, I simply carried it in my backpack. I was able to lock two bikes together to a bike stand in front of stores. I used to carry a heavy duty U-lock that weighs ~6lbs.Its construction is great; looks and feel high quality. It offers much better protection than low-cost cable locks against wire cutter. This folding lock offers a great protection when rider needs to shop at grocery store or grab a meal. Not sure how it will do if bike thief has more time and better tool to cut thru the lock.

This is a unique folding bike lock. It's harder to tamper with than most other locks and can be adjusted at different angles. It comes with two keys and a pole mount for your bike. It has a thin rubber strap that secures it to the mount with a little peg. I question the strength of the hole in the strap, after repeated use I can see it tearing. Time will tell.
