The Kryptonite Evolution Mini D (or U) lock is a favourite amongst bike messengers and hipsters. It’s popularity is no doubt due to it’s combined size (3.25” x 5.5”) and strength.
The small size is perfect for filling the D of the lock with bike (see our guide – How to lock your bike) – any space left leaves an opportunity for a thief to get tools in and pop it open. The size also helps for portability – many people just stick their Evolution Mini in their back pocket. This lock is perfect for leaving your bike for a few minutes. You may find however that using this lock as your only lock (not recommended – always use two locks!) limits where you can park your bike – you can only just fit a tube of your bike frame and a regular bike post through it.

The Evo Mini is small yet strong, with a 13mm steel shackle, hence the 0.9Kg weight. It is rated Silver Sold Secure and rated 9 out of 12 on Kryptonite’s own scale of strength. Kryptonite locks suffered from a flaw previously where the old style cylinder locks could be opened with a pen. The whole locking system has been reworked to use a flat key which eliminates that vulnerability.The bend in the ‘D’ means only one locking pin is required
What is worth noting is the curve in the end of the lock. This allows only one locking pin to be used which is cheaper for production but also means a thief only needs cut the lock in one place to get in. The Kryptonite New York series of locks use two locking pins, which is part of the reason for their higher security rating, and price.
Kryptonite locks come with a guarantee which is in reality, a useless marketing ploy.
In summary, this is a great lock and worthy of the price. I use this as a secondary lock to secure the front of my bike alongside my main lock, a Kryptonite New York 3000 which is bigger and even more secure.
LOCK YOUR BIKE score: 4/5
