The kryptonite front wheel's superior materials makes sure that it ages well with use. This heavy duty U-lock / 4ft flex cable is a must have for bike security, extra deterrent for thieves. It includes a 4’ kryptoflex double loop cable for securing front wheel or accessories. The extra cord is useful for securing additional components, but adds bulk even when wrapped around the frame during transport. The lock moves all around, the mount doesn't stay put and you end up ditching the mount and using Jedi mind tricks to get this fastened to your bike.
The frame attachment is also really well designed and relatively easy to install. The extra cable enables you to lock both wheels for extra security, extra deterrent for thieves. The key comes with a LED light, and you get free replacement keys from Kryptonite.

The lock is excellent and comes with extra keys which is nice. It also includes a flexframe-u bracket providing convenient multi-location u-lock transport. It is great for keeping your bike safe and locked.

This is a very sturdy lock, but kryptonite has created a lock so secure that it is actually difficult for even the owner to unlock it. It is large enough to attach the frame and wheel to many poles or bike racks. The bike has to be facing opposite directions to lock together. The more room the lock has to move around the easier it is to break.
It’s particularly good at locking the frame to a bike stand, sign post or similar. The lock itself opens and clothes smoothly. It is easy to pack and lock, and has enough strength to protect your bike reliably. It is a bit long, especially if you are locking up on conventional posts and bike racks.

If you are searching for a satisfactory lock for your daily usage, you cannot go wrong with this pick. It is the gold standard for bicycle locks. It's easy to install on your bicycle and keeps the ulock secure and out of your way. The frame attachment and flex cable are both invaluable and are holding up well. It is great for protecting all aspects of the bike.
The cable is easy to manipulate and store on your bicycle. It is for basic theft deterrence and it works fine and the cable is long enough to keep your frame and both wheels secure. It would definitely make a robber think twice if it would take more than 5 minutes to break, cut, or pick a lock to get to the goods.

Heavy duty bike holder for the u lock when not in use

Locking the bike with the u-lock through the seat stays to the stable post offers the option to lock up the frame, but has the constraint of less surplus space in the u-lock to secure to a post or rack. It is easy to open and it's very strong. The type face is tiny and the instructions are not laid out in a simple way.
This lock makes for serious short term lockup. It offers unbeatable protection. The anti-theft program is also easy to set up. It comes with a mounting bracket, a cover for the key hole, and is very easy to use.

It can easily lock a frame and wheel to a bike rack or pole. It's great for hooking up your front wheel and frame without a struggle. Because it's considerably long, you can lock at least one wheel and the frame. It's just hardened steel so not much of a match for a cut off wheel.
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. It’s more heavy than other locks however the added security is well worth the small amount of extra weight. It’s great for hooking up your front wheel and frame without a struggle.
Why We Like This:
A plastic bracket with an elastic strap to allow almost any bike frame

The Kryptonite's mount for this lock appears sturdier. It comes with a nice mount to affix the lock to the frame and it's not in the way. It is smaller and means that the lock is completely filled with the frame and post which prevents the lock from being broken apart with a bottle jack. This is a short lock, and it doesn't come with a supplemental cable to wind around and lock your front wheel to the frame & lock.
The Mini-5 is a great second lock. It is used for self defense to ward off a bear or dragon, this thing is a tank. There will not be any affixing of any scooter to a pole or bike rack. The bracket is easy to install and use.
Why We Like This:
Small enough to be attached inside your frame when you ride
Solid u-lock that fits in your back pocket
Nice compact size and nice protective coating to protect bike frame

This is on the small side of U-locks. It lives up to the Kryptonite name and provides excellent protection. It's narrow enough to lock up a frame, fit in a back pocket, or throw in a pack, and because it's so light, it doesn't really add much weight or bulk. It comes with several keys so that's very nice.
This is a good lightweight U-Lock. It provides excellent protection and this lock is worth every penny. It's so light that you can put it in a (big) saddle bag or locked around your handlebar. This will work well if you want to lock up for a couple hours in a not so high bike crime area.

This is the second-highest-rated lock on an independent site that rates locks. It measures to ensure the lowest chance of theft. The U-lock is small for locking a large frame bike such as RadMini Step-Thru Electric Fat Bike Version 2, or RadMini Electric Fat Bike Version. It is built for the street sign posts in ny that are shaped like the van halen or whataburger logos. The clip can be attached to your bike or you may hall it in your backpack.
The bike lock is easily 99.9% visually new HOWEVER it is missing 1 of 3 keys (the LED key) and it is missing the frame bracket to store the lock while riding. This lock will withstand a lot of force.
