The new Kryptonite Messenger Mini is based off the extremely popular Mini-5 U-Lock. For 2015 the Mini has been widened and lengthened so you can secure your bike to more places, without being so large it won’t fit into your pocket.
The 11mm hardened MAX-Performance steel shackle allows for a reduced diameter while maintaining the same security levels at the Mini-5.
A U-Lock wheel extender provides secondary protection for a front or rear wheel. A reinforced cuff over the crossbar and cylinder give you added security and a centre keyway defends against leverage style attacks.
Durability is improved for 2015 with the addition of the new DuoCore cylinder featuring anti-rotation discs reducing the chance your key will get stuck in or break the cylinder.

I bought this as a secondary lock or when I leave my bike for a quick nip in and out of a shop. It is silver rated. You cannot attach it to as much street furniture due to it's shorter length. It does not come with a frame attachment but I think it's for popping into a back pocket although it is quite weighty but what lock isn't. The wheel extender comes off if wished. It also can take a little time to get used to using the key in the lock, you have to ensure the barrels are aligned before the key will fit.

Cable Lock | Use in low crime areas
These are the lightest bike locks. They’re very flexible and easy to carry in your pocket or on your frame. Great as a visual deterrent or secondary lock to fix quick release components to your frame.
Combination Lock | Use in low crime areas
These are cable locks with a 3 or 4-digit combination rather than a key lock. They are great if you don't want to worry about forgetting keys.
Chain Lock | Use in medium/high crime areas
Chain locks are versatile. Thick chain links are great against bolt cutters. You can secure your bike to a range of bulky and unusual objects.
D-Lock | Use in medium/high crime areas
D-locks are strong and often made from hardened steel. You get 360-degree protection for your frame. Locking mechanisms can resist picking and drilling while the D shaping makes leverage style attacks difficult.
Ground anchor | Use in high crime areas
Ground anchors are immovable platforms you fix to your garage floor or wall. When used with a strong chain lock you can fix your frame to the anchor. These offer the best protection for home storage.
In general, the stronger a bike lock, the heavier it will be.
Cable / Combo locks
These range from around 400g up to 1.25kg depending on the thickness and material used in the twisted cable. These are the lightest bike locks for easy transport.
Chain locks range from around 1kg up to 7kg for the thickest and toughest chain locks. Choose a mid-range weight if you're commuting daily to blend strength and weight.
D-locks tend to be 1kg up to 2.5kgs and are more compact for daily use than a chunky chain lock.
A great way to determine the quality of a bike lock is to see if it is Sold Secure Rated. This is a third party, independent rating system.
An approved lock is graded as Gold, Silver or Bronze. The rating is chosen by how long it takes to break the lock and the tools needed to break it.
If you're planning on insuring your bike, many insurers will state you need a Sold Secure rated lock to make a successful claim.
Typically a bronze rating covers a bike up to the value of £500, silver up to £1,000 and gold for any bike worth over £1,000.
These values vary between insurance providers so check the terms and conditions of your provider.
