Walmart offers the GMC Men's Denali 700C Road Bicycle in Yellow/Black size Medium (pictured) or Large for $159 with free shipping. (Amazon sells it in Small for the same price.) That's tied with our mention from two weeks ago as the lowest total price we could find by $27. It features a 21-speed Shimano drive train, side-pull caliper brakes, drop handlebars, Vitesse racing rims, and more.
Don't like yellow? Walmart has it in XL Black for the same price.
