The Kryptonite Evolution Series 4 STD is a reliable, no frills U-lock. I have used the lock for over a year with absolutely no issues. There is no wear and tear on the lock, and no keyhole sticking issues after using it for an extended time. The arc of the shackle is great for finding a variety of lock-up spots and it easily fits around the wheel and frame on a step-through city bike.
I attach my Kryptonite lock to my rear rack through the shackle. It would be nice to purchase a sturdy lock like this with an integrated bike attachment mechanism. I am not fussed by the color of the lock, but it is a bright orange like all kryptonite locks and can be an undesirable color. I don’t lock my bike outdoors overnight, so the security rating is a little high for my usage. Purchasing a lock specific to the rider’s needs is very important because a lock with a high security rating tends to be a bit heavier. I don’t have to carry my lock around, it is always attached to my bike, so the weight does not bother my routine.
Kryptonite has a great reputation for simple, durable locks. I never have any worries leaving my bike locked in public. It is a great high-security lock for daily use.
