Amazon offers the GMC Men's Denali 700C Road Bicycle in Yellow/Black, model no. 92706, for $159 with free shipping. That's tied with our February mention as the lowest total price we could find by $39. This bike has a 21-speed Shimano drive train, 22.5"/57cm aluminum frame, side-pull caliper brakes, drop handlebars, Vitesse racing rims, and more.

Update: Walmart offers it for the same price via in-store pickup.
