I'm looking for critique on the modeling and texturing of this bike

Weird. I like it a lot! A whole lot. First cycle I've seen in a while that managed to seem "fresh".
But of course, the best way to help is with criticism, so here we go:
You have visible tesselation on the inner rim of the rear wheel, and the bump map on the tire treads is kind of grainy. I also personally feel like I would like to see a little more texture detail on the contact surfaces, like the seat, etc. And what about gauges?
Beautiful design though! Hope to see more of your work in the future, whether its new projects or tweaks and iterations of this one!
Thanks for the advice Nonquad. I was so happy to be 'done' that I may have rushed a bit.
