Farley EX 8 is a full suspension fat bike that's built for getting rad in every season. The dual suspension, SRAM 1x drivetrain, and added traction of the 27.5x3.8˝ tires make this mountain bike just as fun in summer as it is in winter. It claws up climbs, bombs through technical sections, and always leaves you grinning.
