How you take a picture of a freestanding bike

I've always wondered how some photographs get taken of bikes, because there's no bikestand behind them, or anything like that, it's like there is literally a bike that is freestanding there, much like this.

And I wondered well that's actually really amusing, there is nothing, well makes for an amazing picture.  However then I stumbled on a really amusing picture.

So that's how it's done, well there's a little bit of a chuckle for you to get you over the mid week hump
