Kryptonite KryptoFlex 1218

It feels like a pretty solid lock, and the tumblers roll well.

As others have mentioned, there's no mounting bracket included, despite the included instructions clearly implying they should be. (Plus, there's no way to contact Amazon Direct to inquire about it.) Not a huge deal,...View More except the mounting clip is permanently affixed to the cable, which unnessarily adds to the lock's clunkiness. The cable itself seems fine for what it is, a "Level 1 Security" cable lock. But I will say the cable itself is less rigid than others I've had,View Less

Used this lock for only 4 time my Bike is already stolen! Absolutely useless! Don’t buy this if you own a good bike

Had the same issue as MDGodfrey. After about a year, the lock would no longer open. Used this regularly for my e-bike. I had to buy bolt cutters to unlock my bike...

I bought 2 about 2 weeks ago for our bikes. They get used about 4 times a week. One is still working fine. On the other the male connector no longer clicked or stayed connected when inserted. I gave it another squirt of silicone...View More and it connected, however, now it won't disconnect. It's stuck in the locked position. Good thing it wasn't locking the bike when this happened. Hence the 3 stars. A follow to review above. Amazon shipped a replacement promptly only to have the same issueView Less
