There are a few things to consider when choosing a Kryptonite u-lock, such as the size of the lock, the level of security you need, and whether you want a keyed or combination lock. The size of the lock is important because you need to make sure it will fit around your bike frame and wheels. The level of security you need will depend on where you’re locking up your bike and how often you’ll be using the lock. Keyed locks are more secure than combination locks, but they can be more difficult to use if you forget your key.
Kryptonite u-locks come in a variety of sizes, so there’s sure to be one that’s perfect for your needs. Their mini u-lock is one of their most popular options and is great for light-duty use. If you’re looking for something with a little more security, their standard u-lock or their New York Fahgettaboudit u-lock would be a better choice. And for ultimate protection, their Chain Lock is tough to beat.
No matter what your needs are, Kryptonite has a u-lock that will keep your bike safe and sound.
