I dont know much about filming/editing, but I watch a lot of biking edits so I will tell you what I see.
The song didnt match the riding at all. If the rider was faster I think it would have fit better, also it seemed really quiet compared to the sounds of the rider but that could just be my headphones. The shot at the beginning could have been axed, or at least put at the end with the other outtakes. Not sure if you did any color grading, but the colors were super dull and there was to much blue to the shots. Also the rider did the same mini-whip off of all the jumps, which got super repetitive especially since its not an amazing whip. finally, the edit seemed to just drag on. I found myself only watching to the end so I could just give you some feedback, otherwise I would have gotten bored. Next time, keep it around 2:00 if the video is similar to this.
What I just told you was comparing your edit to someone like Aaron Laroque's(sp?). Compared to a lot of videos on pb, including mine, its a great edit.
