A large part of why bicycle production moved to China is because the American consumer wanted it to do just that, at least indirectly. Consumers demanded ever-lower prices for basic bicycles, while costs of production rose in the U.S. In order to build bicycles in the U.S. again, the American consumer would need to reconcile himself to higher prices. The quality of the goods probably would be better, but it would take a great deal of convincing the consumer to accept higher prices. I have yet to see evidence this will happen in any substantial way.
