Review on Secure Your Bike with the Kryptonite Keeper 810 Foldable Bicycle Chain Lock by Eddie Duncan

It's obvious that a lot of thought has gone into the design of this lock. The holder is great and I love that it attaches to your existing bottle cage. They could have stopped there, but they also incorporated strong Velcro straps to further attach it to the frame. The lock slides in and out of the holder easily, and after a few vigorous rides I'm sure it will stay there securely. This is NOT a high security lock. I use it to secure my under $1500 bike from Starbucks while drinking coffee indoors. This lock isn't designed to secure your $3,000 e-bike at the train station while you're at work.
