Lock It and Forget it

  • Familiarity: I've used it several times

Kryptonite is the most-trusted bike lock brand for a reason. Their products are bombproof and they have a range of sizes for all bikes. The Evolution Series 4 even comes with a free year of theft insurance up to $3k! With the included mounting clip, you can always have your lock handy when you need to leave your 2-wheeled beauty outside for a while. No need to worry, just lock it up and forget it! No one's going to be cutting through this lock.
