There is a lot going on here. It's a nice image but maybe if you focused on the bike in front and the bikes in the background were out of focus it would make the image less cluttered. Good details though and the black and white adds a nice touch.
I am going to have to partly agree with aclockwork on this one. The black and white is a great touch and I say this because color would have cluttered the image moreso that it currently is. Focusing just on the first bike and the rest out of focus might work as would only getting a couple bikes (3 at most) in the image. Overall not too bad, just a few things to think about for next time.
