Kryptonite Evolution Series 4 Standard U-Lock

kyrptonite Evolution lock -Series-4

The Kryptonite Evolution Series 4 Standard U-Lock is a beefy, beautiful bike lock that offers level 8 (of 10) security. This lock is probably my favorite Kryptonite lock I’ve tested so far. It really makes me feel that my bike is secure. This bad boy comes with three keys and I love the chunky key with the built-in blue light so you can see better in low light conditions rather than fumble around. It’s so cool! And it’s so bright, you could use it in a pinch in lieu of a tiny flashlight–it’s a bit of a stretch (and totally not made for that), but it would be better than nothing, it puts out a surprising amount of light.

The lock is a double deadlock. I’m using it right now with a Flex Cable for the front wheel. Locking is smooth and easy, it’s a real pleasure to use. For travel purposes, I like to U-Lock our two bikes together on the Thule Carrier we use. It’s really hard to steal two bikes locked together, and most bike thieves would move on to an easier target. This lock comes with everything you need to attach it to your bike.¬†Find the Kryptonite Evolution Series 4 U-Lock HERE.
