Bike thieves are a pain in the bottom; I thought that I would get my own back.
Ladies and Gentlemen, I give you . . . the bike spike.
When locking your bicycle in a dodgy area simply remove your saddle and replace it with the bike spike.

I removed the bark and sharpened the stick into a point with a chisel( I also used a surform but it is not necessary).
I tried to stop myself but I could not resist putting on the inevitable blood splash.
I added a rim from a drinks can just to finish it off.

Given a choice of bikes to steal it would be insane to steal the one with a big, bloody spike on it.
"They don't like it up 'em ".
Maybe I'm fooling myself but at the very least it gives passers-by a smile.
Happy Riding ( remove the spike first).
