Compact and Very Secure - Heavy
This bike lock is strong, compact, and easy to carry. It folds up neatly and fits well on the bike without being bulky. Feels very solid and gives good peace of mind when locking up the bike. IT is a little bit heavy but it is definitely built well and I can tell its made of good materials. Simple, high-quality lock that does exactly what you need.

Great security and Easy to Use
I use this lock for both my mountain bike and my mini bike. It's simple to use, feels very solid, and gives me peace of mind whenever I leave my bikes unattended. Some people may find it a little bulky, but good security is worth the extra weight. The build quality is excellent, and the folding design makes it easy to transport and store. Highly recommend for anyone looking for a durable and secure lock.

A big strong lock in a small package
A big strong lock in a small package! This lock folds up and stows very nicely on the bike frame, yet unfolds for much more reach and flexibility than a classic U lock, making it work in more circumstances and easier to lock both the bike frame and one wheel. It takes a little getting used to handling the articulated form and sliding the latch into place, but very high quality workmanship and smooooth operation. We really liked the multicolored version, but it was out of stock (too popular). Fun colors, and a highly visible deterrent. Independent professional reviewers seem to support manufacturers' claims about it being among the hardest to defeat too.

Good Lock, Unreliable Holster
This is a great lock that is fairly lightweight, yet strong against tampering. It isn't going to provide the same level of security as say, a competently designed U-lock, but it gets the job done of locking tires to your frame. I do not suggest using these as a main lock. The lock is easy to use and manipulate, and it does per the name, fold up nicely when done. The compact model is large enough to fit around 26" fat tires plus fenders. The only issue I have with this lock is the holster. The lock snaps into it and is retained via a precise molding of the holster. I only bought these locks ~3 weeks ago, and they have slipped out and flown out onto the road twice already - and that's with no deformation of the holster, just jostling from bumps. And yes, they are attached to my frame with the anti-slip feet installed. Obviously, this creates issues for people that might be driving behind you. I'm planning on just carrying these in a cargo bag instead of using the holsters since they're so unreliable. I hope the next iteration of this lock has a better retaining mechanism that isn't so cheap. They could have just installed a strap onto these to help retain them in the holster and they would stay in fine.

Indestructible Lock
Great lock! Someone obviously tried to cut through my lock and was unable to. They ended up cutting my bike frame instead so they could steal my bike. The fact that after all of that the lock still works is crazy to me. It is easy to use, was easy to install, and was great to just slide into the holder when riding / the bike was not locked up.

High Quality Lock
Excellent high quality lock. Easy to use on a scooter. Folds up, compact, easy to carry. Comes with 3 keys and a bracket to attach to a scooter or bike. Watched videos showing this Seatylock FoldyLock brand hard to cut.

Great all around lock.
I thought I was looking for a small u-lock along with a longer cable for my bike. This was to reduce the amount of room it took up in my backpack and panniers and to reduce the weight they added. (I already had a larger u-lock and cable, which took up a lot of room and weighed a few pounds.) While searching, I came across this Foldylock. It is not a whole lot lighter than my other lock, but it is more compact and mounts on my bike frame. Hence, I don't notice the weight as much. Also, it is quite sturdy. It is coated so that it does not scrape the paint on my bike frame. As advertised, it also does not make any rattling noises as I ride my bike. The price was higher than I wanted to pay, but I don't regret getting it. It has been a handy bike lock, and I carry it all the time. (I only carried my old lock when I thought I would use it was a bother to carry.) It is a quality product.

bunt und stark
Sehr schönes Schloss! Es ist wunderbar beweglich und lässt sich sehr gut bedienen. Mit einem Kilo ist es noch gut transportierbar. Die beiliegenden Befestigungsdinger sehen nicht so stabil aus, da ich aber die Halterung direkt an den Rahmen schrauben kann, brauchte ich sie nicht.

十分好用
工具都無法破壞,但長度比常見的鎖鏈短,上鎖時需要一些訣竅。
