I just had a bike stolen. Two types of locks, secure locking, cable woven through both wheels and frame, U lock on rear wheel Sheldon Brown style.

Unfortunately both locks were Kryptonite; one was picked with a ball point pen and the other one probably was whacked with a hammer.

I detest this brand and I no longer shop at the bike shop where the salesman only last month told me that my two year old Kryptonine U-lock was not one of the 'defective ones'.

It was.
