A hardtail with a rigid fork is the most affordable and most common type of fat bike. Because most of these bikes use four- to
five-inch-wide tires, and because you typically run those tires at low pressure, even a rigid bike can feel like it has suspension
as the tires conform to irregularities in the trail. If your riding surface is particularly uneven, rooty, or rocky, or you want
to run your tires at a higher pressure for less squirm, consider buying a fat bike with full suspension. A full-suspension setup
can help you maneuver better, keep you from feeling beat up after a long ride, and make the ride more enjoyable if you swap fat
rims for standard mountain bike rims. However, if you typically ride in extremely cold temperatures, a rigid fork may be more
reliable
