Long ago I had my eye on a bike that was locked to a lamp post.
Each day I had to walk past it. Lovely bike, everything was quick lock: i.e; saddle, wheels. Think it was a Diamond Back - good make about 10 years ago.
The lock was really rubbish. This went on for about 2 weeks until I finally decided "It had to be mine". Yet the very next day it had gone!
I'm so glad I didn't nick it. I've had 2 bikes stolen from me over the years and I believe that a nicked bike will spit the thief out; under a bus, into an oncoming car; over the handlebars, kill them with fire, etc.
Don't worry mate, the thief won't get far.
It's a Karma thing.
