Super High Quality
The quality is outstanding. I got my first Kryptonite lock back in the 80s, my Mom didn’t my bike stolen, and this product lives up to my expectations. I bought this with the intention of using it while doing some weekend touring, but quickly realized that 6lbs is much heavier than it sounds online. Unfortunately I had to return it, however REI makes the return process very easy, started online and visited my local store to return. If you need a heavy secure lock, buy this one.
Really good lock
Solid. Having the lock built into the chain is a great development
Great lock
Length is great for getting your back wheel and frame. Kinda heavy, but I guess that’s a good thing security wise.
This lock Rocks
Great for large E-bike. Very secure and the chain sleeve is easy on your frame.
Kryptonite to defeat UCSB theives
Kryptonite builds a solid product. My son is at UCSB and we just bought a new bike for him to get around campus. We spent almost as much on the lock as the bicycle. It is a sad commentary on life at UCSB but there it is. Kryptonite still builds a solid product that will take a little more effort to defeat than the U-lock. The lock is heavy.
