  • Good Lock but Susceptible to Rain
Size: 90cm (35.4in) Circumference Style: Forever Max Security 18/18 Color: Black Max Security 18/18
I’ve had it for over a year. Heavy duty lock that works well in a lot of situations that u locks can’t. It is heavy, which I don’t mind. The bend points are susceptible to rain. I had it on top of my car then rode with it on my bike in the folded up position and had to use wd-40 to free it up the following day. That bend gives some resistance but still works. ... show more

  • Best folding lock out there, convenient to carry
Size: 90cm (35.4in) Circumference Style: Forever Max Security 18/18 Color: Black Max Security 18/18
Although a thick chain lock or U-lock might offer slightly higher security, this lock is probably the most secure folding lock currently available. I went with the FoldyLock Forever since it comes with a frame mountable storage sleeve, which makes it much easier to access and store than a heavy chain. Also it offers a little more flexibility than a U-lock, since you can wrap it around wider objects that might pose a problem for a U-lock. It's lighter than a cable lock, but heavier than a U-lock. The key is a high quality automotive style one. ... show more

  • Solid, heavy duty bike lock.
Size: 90cm (35.4in) Circumference Style: Forever Max Security 18/18 Color: Black Max Security 18/18
I recently bought a very expensive e-bike, and wanted a heavy duty lock to protect it when I stop. I didn't want a chain or cable based lock, as I didn't want to have it sitting in a bag on the bike, or banging/sliding around making noise and damaging the paint. Pros: - It folds up neatly, and slides securely into the holder which is easily mounted to the bike frame. It does not rattle, bounce, or make noise of any kind while riding. The mount is very stable. I love the clean look. - The sections of the lock are coated and won't easily damage the paint on the bike. - While no bike lock is entirely theft proof, this one is designed to be very resistant to cutting and wedging (nut splitter) attacks. I feel that this is a reasonable deterrent to quick-hit thieves when you stop for short periods along a ride. It is commonly rated as the strongest folding lock. Cons: - This lock is heavy. At almost 4 pounds, if you are looking for a light-weight lock, this is probably not for you. But as noted above, the weight is a result of the beefy components that are intended to make it stronger and more resistant to portable cutting tools. - The sections of the lock (and the overall length) are the longest I could find, but this could potentially limit the flexibility of what you can lock to. I looked for overall length to help ensure that I would be able to lock my bike to a wider array of bike racks and permanent structures, but the length of the arms can sometimes result in some awkward angles when attaching to things that effectively shorten it's overall useful length. This shouldn't necessarily be a deal breaker, but be aware that this isn't long enough to mount through/around some racks or structures like trees, etc. I can lock my front wheel to my frame on my Aventon Level 2 (barely,) so I can at least do that if I have to, but if you need more flexibility, and security isn't as big a concern, a heavy cable or chain lock might be an option. - Similarly, the bulk of this lock can (at least in the case of my bike) make it awkward to to get the lock out of the mount. (The only place I could reasonably mount mine to the frame of the Level 2 made for a pretty snug and finicky fit when trying to remove the lock from the mount.) I don't mind as I am not often locking and unlocking the bike, just be sure to consider your specific frame when purchasing this lock. - This lock is expensive. At over $100, this is a substantial investment. Considering the cost of replacing a new e-bike, it's worth it to me, but this is a consideration. - The joints can be a bit stiff. They will occasionally bind which requires a little force get them moving again. Not sure why this is, and it isn't a big deal, but I have noticed it. - Super minor nitpick, but I don't like the gold/brass colored plate around the lock keyway. I wish they made a version with a matte black powder coated finish. I did a sloppy/quick paint job with some black gloss spray paint I had around, but I would really like to have seen a black plated version. Overall, I am happy with this super heavy duty lock, and would buy it again. ... show more

  • These are great
Size: 95cm (37.4 in) Circumference X 2 Style: Classic 95 High Security 15/18 (2 Pack) Color: Black
We use these especially when we take our bikes to a city. They are extremely well-built and easy to use. I don’t think the average person could break this lock for sure. They are a little heavy, but I think that’s a necessary evil for this level of quality.

  • Sturdy portable and cool
Size: 90cm (35.4in) Circumference Style: Forever Max Security 18/18 Color: Black Max Security 18/18
Going on year three with this foldilock. Read about it first, decided it was the right balance of security for me. Really love the key lock which is a little different and less likely to be picked. Fits so easily on bike, folds compact into it's holder, hard to tell it's even there, I get comments on how cool it is. Make sure to check that the holder is tight enough every now and then. I once hit a pothole and the whole damn thing flew off. Not a big deal that one time, but depending on what you're doing if it gets loose on you and you take lots of big shakes it could be a thing. It is noticeably heavy but manageable. I carry my bike just the same even with it mounted. Can wrap around wide items for locking. Pay attention to tips online on how to use it safely and decrease opportunities for people to compromise it. A popular tester on YouTube put it through a lot and it performed quite well. ... show more

  • Review after 1 years use
I use on with 2 large E Bikes for my wife and I. I can use to park the front tire of each bike to the rear tire of the other bike and double lock both bikes without any post to even lock to. These bikes with fat tires, triple suspension, dual batteries weigh 100 lbs each so they are a 200 lbs set when locked together. So no way to pick up and run off with them... One key works on both locks and cannot be removed unless the system is locked up. Easy to transport under the frame of the bike. Cannot be cut with bolt cutters and would take some time and lots of noise to use a cut off grinder. Very heavy duty. Zero rattle during transport with included transport case. ... show more

  • Heavy duty and good fit on step through
Size: 110cm (43.3in) Circumference Style: Elite Max Security 18/18 Color: Black
There is no con for these heavy duty folding locks in my case. I am using it on a class 1 ebike with step through frame and middrive motor. It maintains the center of balance of the bike where it is fitted. It is strong and easy to unfold to lock the bike securely.
