Seatylock FoldyLock Compact Folding Bike Lock - Award Winning Patented Lightweight High Security Bicycle Lock - Heavy Duty Anti Theft Smart Secure Guard with Keys & Case for Bikes or Scooters

Bought this lock for just locking up the bike around town. I really like that it mounts to the frame and is always with me. The Velcro straps that wrap around the frame are coated with a sticky rubber to prevent it from slipping. It does slip a little when going over bumps, but it’s still pretty secure. It’s relatively light compared to my giant klunky ABUS U-lock, so I don’t mind the extra weight permanently mounted to my bike. I would NOT trust this lock if I were to leave my bike outside overnight (I keep my bike inside). The metal plates inside the black plastic are pretty thin looking, and I imagine it wouldn’t be too hard to cut through. However, that’s not what I bought it for. I bought it so I could bike around town and lock it outside for an hour while I go into the store or get a beer at the brewery. It’s perfect for this. I trust it for a few hours a day in a low to medium risk situation. Very high quality construction. The keys are high quality and the locking action is smooth and crisp. I keep one on my keychain at all times, so I always have my lock and key with me whenever I’m on my bike. It’s long enough that I can lock two bikes to a pole, but you won’t be able to fit the lock around both the frame and tire if you do this. Otherwise, it’s longer and much easier to fit around a tire, frame, and pole than a traditional U-lock. If you lock your helmet to your bike, be aware that the end is a little too big to fit through the vent holes in my helmet, so I just put it through the strap instead. Really brilliant design. Had this for about a year now, no issues. I just bought another for my girlfriend.

Primary benefit is the compact nature of the lock. Also has some of the benefits of a chain lock in that it can be maneuvered through awkward bike/rack areas. Smooth lock, youtube evidence says these are fairly bolt cutter resistant which is all I can ask for. Great product!

It was a bit larger than expected, so I was worried about the weight on my new bike. I don't notice it at all.This is the best bike lock I've seen and used. Couldn't t be happier, the colors are fantastic, it mounts securely in its cage, which mounts on the bottle cage bosses with the supplied hardware. AND supplied Allen wrench. We all have a bunch of them, but this one's the perfect size so glad to see it was included.I didn't try the other mounting system.It's easy to use, fun to use honestly the way it folds out.Feels rock solid, no question about it's security.10/10Great value too

The media could not be loaded. Very solid, and heavy, combined with a very loud alarm (that was purchased separately) I do not think anyone will be wanting to saw through this monster. Also much easier to manage than my coiled lock. $95 is a bit much but to deter thieves from stealing your bike that costs way more I will say I do NOT have buyer’s remorse. It is worth the cash.

I like that I got a set of two for two bikes and can just bring one key for both. The part that is difficult is that you need to use the key to open the lock and then keep it in to get it to close. This can be really difficult when locking it to something. The lock isn't very long so it is tricky to use a key the whole time and get it to close. I have similar older locks that just click shut without the key so I miss that. The length is fine, it keeps the weight down, but it's just a tricky system!

What an amazing and innovative bike ‘folding’ lock. If you’re seeking a cleaner, less obnoxious look, than the ‘standard’ U-bolt bike lock, this is it. Plus it offers superior anti-theft deterrence features.Yes, it costs more at $80 (on sale); but if you regard your bike as an investment or an essential equipment, then the FoldyLock (aka SeatyLock) will offer greater protection, along with greater piece of mind.- Mounting Issue: One concern that I had was where to mount it on my bike frame. I preferred the 'stem’, so I immediately mounted the lock holster to the mounting screws on my bike.But then I tried to slide in the FoldingLock into the holster. Ugh! It wouldn’t fit! 'When 'fully-folded', the length of the stem (i.e from the top bar to the crankcase) was too short (14.5”in; 36 cm).I groaned with frustration b/c I didn’t want to install it on the lower bar, where I mounted my water bottle. Then I discovered a technique (hack) to make it work, which I describe in the photos, below. So if your bike stem is a short (35-38 cm), perhaps try this method:Steps:1, Place the folding lock over the opening of the holster2. Push out the longer ‘outer’ bars (black) away from the holster and push the inner ‘’orange’ bars over the holster3. Partially slide down the inner ‘orange’ bars into the holster about 1/4” to 1/2”.4. Slide the outer ‘black’ bar so that it realigns straight with the orange bars.5. Slide down the FoldingLock into its holsterThat’s it! All I needed was an extra 1/2” of space, but this method offers that space.Luv the final look and finish!

This is probably the best and tidies lock I used. Very sturdy. Worth the price for sure.

It's definitely easy to mount and carry on your bike or scooter in a compact fashion, it comes with 3 keys which is great for people who misplace keys. It certainly seems solid and difficult to break, but I can't say I've tested it for long periods or anything. I guess if it fails me, I will update my review, but so far, it seems like a secure choice.
