Understanding Kryptonite Locks

Kryptonite are a very well respected name in the field of bike locks, and offer a range of different U-locks and chains.

To make things easier to understand, all Kryptonite locks are colour-coded to indicate the level of security offered:

  • The Yellow locks are classed as Ultimate Security and are given the name “New York”. They are suitable for high risk bike theft areas such as inner cities and college campuses. I have one of these for use in Dublin – the Kryptonite New York 3000 – it’s really heavy to carry around on my bike, but it would also be very difficult for anyone to break open.
  • The Orange locks are classed as High Security and are give the name “Evolution”. These are lighter and offer less protection than the yellow locks, and would be suitable more more moderate theft risk areas such as the suburbs. However, I’m told the Kryptonite Evolution Mini locks are very popular with the bike couriers in the city, because of their good trade-off of security against size and weight.
  • The Grey locks are classed as Moderate Security and are given the name “KryptoLok”. These are only really suitable for low risk areas. I used to use one of these with my first bike, but then again the bike was rubbish and not really worth stealing!

Within each range of locks there are a number of options available, and you can choose between U-locks or chains, depending upon your requirements. Both U-locks and chains both have their advantages, and for high-risk areas you’re better off using both, as many bike thieves only carry enough tools with them to tackle one kind of lock – either U-lock or chain – but not both.

And, of course, with any lock you need to know how to lock your bike properly to make it as secure as possible.

    concerning Kryptonite Locks, my son’s Specialized bike was stolen in a parking garage in the Docklands. The thief must have a grinder to cut it!
