FoldyLock Classic Folding Bike Locks - Set of 2 Matching Bike Locks with 6 Identical Keys - Patented Heavy Duty Anti Theft Locks with Carrying Cases for Bicycles E-Bikes and Scooters - 95 cm

This is one heavy duty lock. Stronger than all the rest. If you lose the key, good luck just go buy new bikes.

Only a few cons. Sort of awkward connecting it to certain bike racks. Encountered a few where it wasn’t long enough to connect to the lock to use. Also the edges will scratch the paint off the bike surface. Be careful.

They are not light weight - but not meant to be. That was an odd question. These are excellent bike locks. We use them for ebikes. Nice to have two for a couple, and keyed the same! They could be a little longer to accommodate more bike locking scenarios. But that's a trade off with how compact they are (nice!) and how easy to cut they are (not at all).

Heavy locks for our Ebikes! They fold up and fit in the holder well. We carry them in our bike bags and love having the same key for both locks.

Happy I found this lock, it is a solid deterrent and reasonably priced. The lock is easy to use and the harness is excellent. No vibration and stays put while riding over the bumps. Because of the relatively short length, it is sometimes difficult to get a larger bike close to what it is being secured to.

We got the two lock package. They were keyed the same, which some reviewers had me worried they would not be. I like how we can attach one to the other to make a longer lock or use separately.

I like it so far. The lock has some weight and is a bit stiff, but I don’t think that is a negative. My only complaint - it is difficult to remove from the cage/holder.

While no lock is 100% pick-proof, and nothing will stand up to a portable grinder, this lock is beefy enough to slow down a potential thief - hopefully causing them to pick another bike to steal instead of yours... I bought the "twin pack" (2 locks that use the same key) because I can use them end-to-end to extend the "reach" so I can go through my e-bike's frame, rear wheel (where the motor is), and rear rack, then lock it to an immovable object (tree, lamp post, etc.), even if it's not real close to the bike. The mounting system holds the lock securely to the bike, and holds them quietly while you're riding. So much nicer than a heavy-duty u-lock than clanks around while riding, or a flopping cable that can be cut in <5 seconds anyway... Highly recommended!

This lock is larger than expected, but it look and feel sturdy.
