A lot of high end bicycles are made in the USA (Trek carbon-fiber frame bikes for example, but the current Trek CEO is a WI leftie unfortunately). On the low end there is this USA supplier for Walmart: http://www.bca.bike

Oh thanks.
“Trek Bicycles is the largest U.S. bicycle company and they’re the only major manufacturer still producing two-wheelers in the U.S. Overall, Trek makes roughly half of the bicycles manufactured here in the United States. Despite Trek’s American-made legacy, U.S. made bikes account for only about 1 percent of Trek’s total production. Trek makes 4 models in their Waterloo manufacturing facility...the Session, Madone, Speed Concept and Emonda.”
