Every season is prime riding season with a fat bike. Extra-wide fat bike tires create a much larger contact patch than normal MTB tires that lets a fat bike “float” over loose terrain and find traction where regular mountain bikes might struggle. Take them to a sandy beach or pedal your favorite local loop when it’s covered in snow during the middle of winter. Or just hit regular singletrack trails and gravel paths with unmatched comfort and confidence. With a fat bike, the variety of terrain and conditions you can explore expands dramatically.

The Best Fat Bikes: Fat Tires Matter

It's safe to say that fat bikes have come a long way since builders were creating double-rim double-tire bikes like the 1992 Clark-Kent fat bike that was built to ride the snowy course of the legendary Iditabike race. Now, modern fat bikes are lighter and more refined than ever.

Fat bikes typically use 26” wheels and tires (though there are a few 27.5” fat bikes too).

In general, fat bikes can be categorized as either 4” fat bikes or 5” fat bikes, which refers to the tire width the frame is designed to clear. 4” fat bikes generally fit 3.8-4.0” wide fat bike tires while 5” fat bikes generally clear 4.6-4.8” wide fat bike tires. 4” fat bikes are lighter and more nimble, while 5” fat bikes have more “float” due to the wider tires. 4” fat bikes are generally better for all-around riding while 5” bikes are best for the loosest conditions like fresh powder and unpacked snow. 

Rigid, Hardtail, and Full-Suspension Fat Bikes

Most fat bikes will either be rigid bikes with no suspension or hardtails with a fat bike-specific suspension fork. Suspension generally isn’t necessary for fat bikes because the extra-wide tires allow them to run very low tire pressures, typically sub-10 PSI for those fresh pow days. There are a few full-suspension fat bikes, but they’re extremely rare, and most major manufacturers don’t make full-suspension fat bikes because they heavy and complicated. 

Lucky for you, The Pro’s Closet has a large variety of fat bikes so you can choose the best option for your riding preferences. Be it the popular Specialized Fatboy or the elusive full-suspension fat tire bike, the Salsa Bucksaw, TPC will help you find the ultimate used fat bike. 

Specialized Fat Bikes

The Specialized Fat Boy is the premiere fat bike from the big S, and one of the most popular fat bike models on the market. It’s able to clear massive 4.6” tires which provide a hovercraft-like feel over any terrain. 

Trek Fat Bikes

The Wisconsin-based manufacturer produces the Fatboy’s biggest rival, the Trek Farley. With multiple build options available that can fit any price point, the Trek Farley is perfect for those just getting into the fat bike game or riders looking to obtain the ultimate fat bike build.
