Best With One minor exception: Kryptonite No Lock

Buy on Amazon

Even inside your home or apartment, a burglar might decide that hey, this bike will make a nice getaway vehicle. It is a really significant lock, with a lot of weight. The extra length over the'mini' sizes make it easier to lock to poles and stands that are just out of reach. It comes with a great bike mount, and so the lock sits just right.

The build quality of the lock and keys is superb. It’s heavy-duty, extremely tough and durable and locks the bike tightly. They also offer a key replacement for registered keys and anti-theft Protection program if you register within 30 days of lock purchase.

• Very secure in heavy downtown urban environment
• Very durable, very easy to use
• Delivers what they promise

Best For motorcycle: Kryptonite Secure Lock

Buy on Amazon

There's definitely no way to use this lock to secure both your tire and fork as you can with most normal sized u-locks without using a secondary lock. This lock will easily fit standard tires and a standard bike rack pole. The fact that it's mini means that there is less room between your bike and the lock. The lock itself is sturdy, which works to secure a bike. The chains give you a lot more flexibility.

The lock is 100% secure from theft as any grinder can take out even the most highly rated lock. This is great for securing the front tire to the frame or the frame to a post is not really ideal to lock three items at once. It offers great protection and has deterred any future thefts.

• Heavy as a bag of rocks
• Very great choice if you are trying to protect your bike
• Works well and is heavy duty

Best For All Bike needs: Kryptonite Fahgettaboudit Lock

Buy on Amazon

It is a must for the urban bicyclist. This mount feels really sturdy and it has a strap that can fit around just about any part of your bike. It moves the hoodlums down the bike rack where they can grab a ride from some fool who economizes with a master lock on a chump chain. It's heavy duty and much heavier and thicker than the regular strength versions, so it's appropriate for people who need super secure bike locks, but less so for bikers who do not need heavy duty strength.

The size is convenient for securing the frame and either the front or back wheel to a thicker parking meter pole, which the smaller U-locks cannot do. They really need to go back to the drawing board with the mount design. This lock should be able to secure a bike for at least one night in high theft areas if paired with a good secondary lock.

• Great mount provides flexibility and comfort
• Sturdy, you will love the weather cap on the key slot
• Sturdy and secure but quite heavy

Best For money: Kryptonite Bike Lock

Buy on Amazon

The kryptonite bike lock's superior materials makes sure that it ages well with use. The U-Guard plus the extra steel wire is great for protecting all aspects of the bike. It fits around your back tire, bike frame, and bike rack when locking so thats great as long as the bike rack isn't too thick. It's secure and you will love the mount it comes with.

The included mount is handy as well. It includes a new transit flexframe-u transportation system which allows for versatile carrying. It's a solid lock, long and wide enough to lock your gear to whatever you may need. The flex cable adds an extra security feature and gives you a piece of mind. It works fine and the cable is long enough to keep your frame and both wheels secure.

• Heavy duty bike holder for the u lock when not in use
• Wire is great for a second bike or locking the wheels
• Good investment for long term

Best For electric Bike: Kryptonite Good Lock

Buy on Amazon

This is a fantastic all-around lock. It fits street signs and most bike racks. It includes a flexframe-u bracket providing convenient multi-location u-lock transport. Because it's considerably long, you can lock at least one wheel and the frame. It’s more heavy than other locks however the added security is well worth the small amount of extra weight.

Love this bike lock and it has been improved over the previous design and locks both ends without rocking one end in before you can lock it. The attachment has an intentional half moon shape for round frames. Because it's just hardened steel so not much of a match for a cut off wheel.

• A plastic bracket with an elastic strap to allow almost any bike frame
• 14 mm hardened max-performance steel shackle
• Good investment for long term

Best For beach cruiser: Kryptonite Great Lock

Buy on Amazon

Primarily this lock receives high marks due to its compact size and ability to secure it without any space between bike and secure support. It includes a strap and mount for the bike so you can tuck it on the bike and not worry about forgetting it in a bag or what not. The double bolt is a great feature because the key controls bolts on *both* sides of the lock requiring a thief to cut both sides of the lock before releasing the bike.

The lock comes with 3 keys and a holster to attach to your bike. The weight of this lock is equivalent to about a textbook and a half,it's heavy. It is better to use as small a lock as possible to reduce the possibility of using a crowbar to get leverage on the lock.

• Heavy for a u lock, but easy to use and solid
• Very sturdy and comes with 3 keys
• Very secure, and very well made

Best For college kids: Kryptonite bigger Lock

Buy on Amazon

Compared with other products by Kryptonite, the kryptonite bigger lock has a convenient design. This U-lock is very small and lightweight. It is compact, well-protected by its rubbery coat, and smooth to operate. It has a great bracket to store easily on the frame. It's also great for quick trips to the corner store, coffee shop, etc, when you don't want to wear your messenger bag/backpack-just throw it over a handlebar and go. It has two types of keys.

It is easy to use and very heavy duty. They aren't too heavy and they fit in a back pocket, so that's nice and portable. It is perfect for figuring out that pesky little rubber piece.

• Perfect for a daily commuter bike
• Great little lock that snaps in well when attached to
• Good brand reputation

Best For belt: Kryptonite lighter Weight Lock

Buy on Amazon

Best part: kryptonite lighter weight lock costs comparatively low and it is available to ship in 24 hours. The shackle on the Messenger Mini is longer than the Evolution Mini-5, a bit shorter than the Mini-7, but half an inch wider than either. This is the perfect balance of lightweight and secure (7/10 on the kryp scale) for being a daily rider in a high-theft city. It has a design for ease of use. It can be defeated with a single cut, but it is well enough made that this would take several minutes at least.

This lock won't be cut with a bolt cutter, so a grinder would have to be used. If together, it will fit in most water bottle holders, and the open area of the pack provided you have padding between your back and the lock. The opening is wider to fit around large racks / tire & frame, but thinner material makes it slightly lighter than either. This is a great lock for quick stops, or areas in clear public view where a cutting attack would be impractical.

• Easy to take with you and just big enough to lock up
• Increased shackle dimensions allow for flexibility with lock-up
• More versatile than the mini, great for belt holster, fiddly keyhole
• Shackle design for ease of use
