Went out today to take daughter no 2 to work, Daughter no 1 is out on my bike just pottering around as she's recently passed her test. Gets home to find my bike's on the drive. Daughter 1 says" Dad i've done something stupid, sorry i've put the disk lock on the wrong way" "Thats ok" I say, "just put the key in through the other side of the wheel", ...You know whats coming dont you....Yes there's lots of holes in the disk and only 3 spokes in the wheel, she chose a hole next to a spoke so you cant get the key in...Doh
