Figured since there's a thread running on this right now (Confused About Ed's Photo) I'd move my comments over here as well. :D
I find the photo interesting and engaging. It has enough storyline initially to make me look a bit deeper. I say storyline based on the combination of the cyclist and his shadow. It makes me look twice to try and see what it was that captured the photographers attention. In this case I think the "trick" is the shadow riding the handrail. I also like the play of light and shadows (with the exception of the large block - looks like a planter - in the top left).
Compositionally it has a nice flow using leading lines from the cyclist, to his shadow on the wall, then following the handrail and stairs down and out of the image. Normally the down and out of the frame is somewhat taboo but here it adds a sense of motion to the photo and there is just enough room for the cyclist to "move" into.
