Seatylock FoldyLock Classic Folding Bike Lock - Patented High Security Sold Secure Silver Bicycle Lock - Heavy Duty Anti Theft Secure Guard with Keys & Case Mount - 37.4"

The best device to prevent theft

Quick learning curve for use. Won’t scratch. As advertised. Seems heavy duty. Recommend attaching to bike with mounting screws, not the clamps. Seems like it would eventually loosen or break with ties supplied.

I bought this for my son and his electric scooter. This model was a bit heavier and bigger than I imagined, but for short term security, it's great. It enables him to run into a store for a minute or two. And I like this better than a U-lock because its flexibility allows it to be wrapped around objects of different sizes. It's not cheap, but I'm happy with it.

This lock is definitely on the heavier side and a bit pricey, but it feels super solid and reliable. You can tell it’s built to last and gives real peace of mind when leaving your bike in public places. The folding design is compact and easy to mount on the frame, which is a nice touch.If you're okay with a little extra weight for better security, this lock is totally worth it. It feels like it would seriously slow down any thief!

This thing's a bit heavy, but works like a charm. I haven't tried leaving my e-bike in a sketchy alleyway with it, but for less foolish use, like coffee shop trips and grocery runs, it has been perfect. Three years in and I still have my bike and the lock is still working great.

This lock is absolutely strong as a tank and built like one as well. I highly recommend this lock to anyone who values there bike, e-bike, or motorcycle ect.. For the locks quality and it’s toughness I’ve given it five stars, also because the lock is such a good product it truly has earned five stars on its own merit.

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.

These things are beasts and I love them. Mounted well to our bikes and I appreciate the matching keys. Nice to be able to store them out of the way on our Aventure.2 bike frames.
