Best For ebike: Kryptonite Hardened Steel Shackle

Buy on Amazon

If you are looking for a popular lock for your regular usage, you cannot go wrong with this pick. The bike mount is very sturdy, with no rattles. It features, providing advanced protection against twist and single cut style attacks. The bracket slides up and down and around the tube it is fastened to. It feels very secure and heavy. The lock is simply too heave and its weight easily overcomes the friction with which the Bracket is "secured." It’s particularly good at locking the frame to a bike stand, sign post or similar bike racks. It is a bit long, especially if you are locking up on conventional posts and bike racks.

Why We Like This:

Heavy as it looks, a safe choice for your bike
Disc detainer lock which is very smooth
Lot of satisfied buyers

Best For money: Kryptonite Bike Lock

Buy on Amazon

The features department is where kryptonite bike lock truly manages to shine. The key hole guard creates a lot of weight on your road bike whether your mounting it or carrying it in a bag. 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 does add weight on your road bike whether your mounting it or carrying it in a bag.

The ulock has a hidden keyhole that you can access by turning the black cover. The cable is easy to manipulate and store on your bicycle. It's secure and you will love the mount it comes with. It's 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. A decently sized bolt cutter will get through this, and it is a decent lock for suburban/rural areas, NOT NYC.

Why We Like This:

Great lock with great security and peace of mind
Heavy duty bike holder for the u lock when not in use
Good brand reputation

Kryptonite makes beautiful and great lock with classic and smartly choosen materials. This size is nice when you need to lock more than one bike up. It has a design that is really excellent and big improvement over the previous designs that kryptonite used to use. It comes with a mounting bracket, a cover for the key hole, and is very easy to use. The lock is quite heavy. The type face is tiny and the instructions are not laid out in a simple way.

The key is more complicated, the keyhole is small and has a built-in cover. It looks more useful and it doesn't scratch the. The anti-theft program is also easy to set up.

Why We Like This:

Adjustable so you can ensure it clears the pedals
Very sturdy and comes with 3 keys
Heavy for a u lock, but easy to use and solid

Best For Any type Of Use: Kryptonite Good Lock

Buy on Amazon

The features department is where kryptonite good lock truly manages to shine. The longer shackle model of the lock can be a little bit harder to store on a bike however, especially if you use bottle cages. It is made of very soft metal. As you tighten the screw, it draws the strap and rubber sections (doing the actual holding) tighter. The release mechanism feels less likely to snap, and the installation of the kit includes the use of a webbed strap and metal buckle (the bike is protected by a rubber insert) that firmly attach to the bike frame.

Functionality is great but the included mounting bracket uses a small Allen type screw which is made of very soft metal. There's a nice little cover on the lock/key opening to keep grunge out. The mounting bracket is nice, which keeps you from having to lug this around.
