Walmart offers the Genesis Men's 26" V2100 Dual-Suspension Mountain Bike in Black or White, model no. 92688, for $129 with free shipping. That's tied with last week's mention as the lowest total price we've seen, and a current low by $42. It features suspension on both the front and rear forks, an alloy 4-bar frame, disc brakes, and 21-speed Shimano gearing.
