Not trying to be rude, but a lot of people try B&W to try and enhance something thats not too clever to start with... and thats about the worst excuse ever for B&W.
Other than trying to be "retro", the only other use for B&W in my book is when you have textures (that cause shadows, so naturally leaning to light and dark) and the shot is *about* texture.
So, I don't think the shot was all that to start with...bike dead centre frame, a little bit soft, nothing really going on, not terribly interesting background and a mix of old and modern.... and B&W didn't make it any better for all of the reasons above...
sorry!
