Looks like this was taken using on camera flash. Ambient light, whether using 500w work lights bounced off a reflector or natural sunlight, usually works better than on camera flash. Just a suggestion.
Nothing in this photo seems very compelling to me. It looks like it was taken with the camera flash, I think better lighting would have helped. The fender of the close bike is washed out and distracts from the photo.
Nice composition with that almost diagonal wheel in front. but it is overexposed. Otherwise this is more the metal "stripes" in the wheel than wheels. (sorry my english)
