The Kryptonite Mini - 5 Evolution lock is a top - notch security solution. It comes with a 13mm hardened MAX - Performance steel shackle that stands up well against bolt cutters and leverage attacks. A brand - new patent - pending hardened double deadbolt design offers extra protection against twist attacks. Its high - security disc - style cylinder is resistant to picking and drilling. Anti - rattle bumpers keep the noise down during transport. The lock also features a sliding dustcover, includes a frame bracket, comes with 3 stainless steel keys, and has a protective vinyl coating.

Using this Kryptonite Mini - 5 Evolution lock is easy. First, install the frame bracket on your bike frame if you want to carry the lock conveniently. To lock your bike, simply open the lock using one of the three stainless steel keys provided, wrap the shackle around the bike and a fixed object, and then close it. When not in use, slide the dustcover over the keyhole to protect it from dirt and debris. As for maintenance, keep the lock clean by wiping it with a dry cloth regularly. Avoid exposing it to extreme weather conditions for long periods. If you notice any signs of damage, like the shackle getting bent or the lock not opening smoothly, it's time to get it checked or replaced.
