Could have really pushed the levels hard to get it really gritty and dramatic to further enhance the subject. Lovely cropping. Some might say its too tight but I think it makes it quite abstract
Nice textures are created in the rust and the different forms of paint. I might have preferred a slight crop off the left to not include the trees. While I see you wanted to include the handlebar I think the trees take away more from the photo than the handle bar gives. I do like the overall composition of the photo though. From the cut of tire, and the repeating round circles. Good lines.
