Kryptonite

Evolution Series 4 1016 Integrated Chain Lock

Sure, there are plenty of days that a quick and lightweight cable lock will do the trick, but that won't suffice in the city, and certainly can't be trusted to keep your pricey steed safe for your full 8-hour work day at the office. That's what the Kryptonite Evolution Series 4 1016 Integrated Chain Lock is for — giving you big protection from the city streets, and long hours of leaving your trusty steed unattended. The Kryptonite Evolution Series 4 1016 works like a body-guard for your bike. It uses 10-millimeter 3M Manganese steel, tucked inside a nylon sleeve to keep your frame scratch free, while securing it to the fixed object of your choice for all day security.

The Evolution Series 4 features burly construction that is cut resistant, and uses an end-link design that fastens to a hardened deadbolt, so even what is typically the weakest part of the lock is hardened for the streets. The lock uses a disc-style cylinder that's both pick and drill resistant, and a nice little dust cover to shield the internals if the day's worst enemy is rainfall. The chain comes in at a whopping 5-and-1/4-feet long, giving you the space you want to hoop in your front wheel when locking up, or lock to large objects. Its power does, however, come at one cost — weight— scaling in at 9.7lb, making it a decent lock for tossing in your messenger bag or backpack, but not ideal for carrying on quick errands. It rates a solid 8 out of 10 in Kryptonite's security scale, meaning that Kryptonite trusts it so much, it will help you pay for a new bike if your trusty steed is taken at fault of the lock, all you have to do is register your bike and lock with Kryptonite after purchase, so you have extra peace of mind when you're stuck in the office working late, or hitting the local dive bar for a pint on the way home.
