Bike Locks Heavy Duty Anti Theft Bicycle Lock Folding 4-Digit Level 6, Security Chain FoldyLock with Bracket, 2.8 FT Strong Foldable Lock

Great lock! Well made, heavy duty and compact. Fits very snug on the seat post.

The media could not be loaded. I don't know what people are talking about how it doesn't stay on their bike or falls of??? I don't think they're attaching it correctly. My only concern would maybe be how strong the rivets really are.

I really don't want to make it seem like this isn't a great product. It looks and feels very very well made. but the rivet joints give me a worry because they are what feels in my hands like the weak points in the links, which feel very solid and very well made in the actual links. but the rivets, each joint feels in my hands like i could break them, The caveat is that I'm pretty strong, about as strong as the average big guy. I'm not saying it is flimsy at all, I'm just saying the joints in my hands felt like i could probably break them.I couldn't bring myself to apply any good amount strength against the joints because I didn't want to end up having purposely broken the item before returning it, which would be wrong. I decided to play it safe and just return it in perfect unbent condition and go for another style of lock.YMMV, I thought it was important to bring this up because other than that one thing, which again, is only my own subjective feel of the links that made me believe that the joints should have been made thicker, or sturdier for my own peace of mind, maybe try it and see how they feel for yourself.Absolutely everything else about this item is excellent. The combination lock looks and feels solid and strong, and the locking mechanism is brilliant. The mount with the built in reflector that locks the lock to it is utterly brilliant.In the end, most bike locks are only going to be so strong, so I guess I'm going to have to take some more time looking for the best tradeoff of convenience/performance I can find.

Practico, no tan pesado, y de buena calidad

Son bikes all over town and uses this when going into stores or stopping in a park.We LOVE:-Too fat to cut with a quick bolt cutter. a thief would probably go to the next bike if they saw how fat the metal is.-easy to open and close. just be careful not to forget the combination.WE DONT LOVE- we could not get it to stay on the bike when not in use. so my son takes a backpack specifically for water and this lock. i wish the lock on bike mechanism worked, but it never worked. he tried, my husband tried, i tried. so if you are depending on that feature, look elsewhere.-it is heavier than other locks, but that is because of the quality thickness of metal which is what makes it a good anti theft device. the weight is worth it. but it does feel like a heavy rock in the backpack.

This lock was great for around 1year. I liked that it was compact and seemed very secure. On the plus side there was an attempt to steal my bike but the thieves couldn’t break through the lock itself, you could see the saw marks of their attempts but luckily for me they gave up. That evening 2 other bikes were stollen from the same spot but I was fortunate because of lock. Anyway… the reason this isn’t a 5 star review. The locked jammed while securing my bike outside my apartment. I’ve had to smash the lock to get my bike free. The code was correct but the latch mechanism had jammed, I had to hit the unlock button with a hammer for it to release. Luckily it happened at home and not while I was out or I’d have been stuck. The locking mechanism has been a little temperamental for a while but I didn’t expect it to completely lock up. It’s a shame as it has been great but I don’t trust the brand enough to purchase another one. If they can redesign the locking and releasing mechanism that would be great. Overall it’s a super secure lock, good design but I need a better release mechanism. I daren’t lock it again at this point.

Decent lock with extremely poor inadequate, mounting system! This could’ve been solved by providing a plastic holder that fits in a water bottle cage as shown in my photo. I was able to jury rig this by taking a plastic bottle sold at Dollar tree and cutting off the top. The bottle fits perfectly in a Cycling water bottle cage with the lock inside.The provided lock mount is flimsy and unless you have adequate space in your seat, tube will likely not fit either.The lock will discourage some amateur thieves, but it is certainly not a high security solution

After trying several methods for securing my expensive e-bike I have finally found a solution that I find is versatile and easy to use. I tried a keyed folding lock but didn't want to carry another key. This strong combo lock plus a looped steel cable offer a wide range of security options for leaving my e-bike unattended. I actually carry a strong combination lock (set to the same combination) as well to provide even more flexibility. Mounting the lock to the seatpost is trivially simple and it looks good on the bike.1- Used by itself through the chainstay and rear wheel offers a good option for a quick stop because the bike weighs 60 pounds and is hard to carry.2- If I can park close enough to a fixed post/rail I loop the lock around the post as well.3- If the lock is too short to reach the post/rail I pass my cable around the post and then secure it to the bike with the folding lock that I have attached to a wheel.4- If there is no post I use the padlock to attach one end of the cable to something immovable, like a chain link fence or an eyebolt.I added a concealed Apple AirTag for the unlikely case when someone defeats all of that hardware. Then you and the police can track it down. BTW: If you can locate your stolen bike DON'T try to recover it yourself. Let the police do their job and recover it for you.I highly recommend this lock.
