First single speed project - help!

That singulatored bike up there ^^^ is from those people off gumtree isn't it?

http://www.gumtree.com/london/09/20584009.html I'm surprised they haven't got some stick from here yet...

The black gate bike 'on red tyres' they have on there seems to have had it's forks un-raked using the 'crashing into something' method!
