Kryptonite KryptoFlex Cable Lock

The Kryptonite KryptoFlex Combination Cable Lock is provides a medium level of security and a high level of flexibility. The four digit combination locking mechanism is convenient because you never have to worry about remembering to bring a key. In addition, the flexible six feet long cable allows you to secure a bike to an assortment of racks and other immovable objects. However, a cable lock's flexibility comes at the expense of reduced security because they are easier for thieves to cut than are U-locks. If you lock up overnight or in a high risk location then it is advocated to also use a more secure but less flexible U-lock. The following picture shows the Kryptonite KryptoFlex installed underneath my bike seat and seat pack.
