A fatbike (also called fat bike, fat tire, fat-tire bike, or snow bike) is an off-road bicycle built to accommodate oversized tyres, typically 3.8 in (97 mm) or larger and rims 2.16 in (55 mm) or wider, designed for low ground pressure to allow riding on soft, unstable terrain, such as snow, sand, bogs and mud.[1] Fatbikes are built around frames with wide forks and stays to accommodate the space required to fit these wide rims and tires. The wide tires can be used with inflation pressures as low as 34 kPa; 0.34 bar (5 psi) to allow for a smooth ride over rough obstacles. A rating of 55–69 kPa; 0.55–0.69 bar (8–10 psi) is suitable for most riders.[2] Fatbikes were developed for use in snow or sand,[1] but are capable of traversing diverse terrain types including snow, sand, desert, bogs, mud, pavement, or traditional mountain biking trails.[3]
History

Picture from series "Strange but True!", placed by Currys Ltd in the cycling press, before 1932Early versions of fat-tired bikes were probably built as long ago as the early 1900s but modern versions were not developed until the 1980s. An early example is the custom three-wheeled in-line longtail-style bike with fat tires, designed by French cyclist Jean Naud in 1980 for desert travel. He rode it from Zinder in Niger to Tamanrasset in Algeria,[citation needed] and later rode a similar bike in 1986 across the Sahara using prototype fat tires from Michelin.[4]
In the late 1980s, Alaskan frame builders began experimenting with custom components and configurations designed to achieve a large contact patch of tire on snow. Steve Baker, with Icycle Bicycles in Anchorage, was welding together two rims and even three rims and built several special frames and forks that could accommodate two or three tires together. In 1989, Dan Bull, Mark Frise, Roger Cowles and Les Matz, rode the 1,000-mile (1,600 km) length of the Iditarod Trail.[5]
Simultaneously, in New Mexico, Ray Molina had commissioned Remolino 3.1 in (79 mm) rims, 3.5 in (89 mm) tires, and frames to fit them. He wanted the bikes for his guided tour business in the soft sands of the Mexican and Southwest arroyos and dunes. Mark Gronewald, owner of Wildfire Designs Bicycles in Palmer, Alaska, met Molina at the 1999 Interbike convention in Las Vegas and rode one of Molina's prototypes at demo days. In late 1999, Gronewald and another Alaskan frame builder, John Evingson, collaborated to design and build several bikes using Molina's rims and tires. Gronewald and Evingson then began producing their own separate lines of fat-tired bikes in 2000. Rims and tires were imported to Alaska where Wildfire and Evingson began making small, handmade production runs and custom-ordered frames built around Remolino 80 mm (3.1 in) rims and 3.5-inch (89 mm) tires. Gronewald coined the trademark "Fat Bike" in 2001 and used it as the model name for his bikes. Gronewald initially worked with Palmer Machinery for welding and later contracted frame building to Mike DeSalvo at DeSalvo Cyles of Ashland, Oregon. Gronewald continued to sell his original fatbikes until 2011. Gronewald's design featured an 18 mm (0.71 in) offset wheel and frame built to allow full range gearing, since he was using standard hubs and bottom brackets available at the time.
Wildfire and Evingson bikes were used in the Iditarod Trail races beginning in 2000. Also that year, Mike Curiak from Colorado set a record on the Iditarod Trail in the IditaSport Extreme race to Nome on a modified Marin bike with Remolino rims and tires. Surly Bikes released the Pugsley frame, in 2005,[6] and began producing Large Marge 65 mm (2.6 in) rims and Endomorph 3.8-inch (97 mm) tires in 2006. The Pugsley frame, rim and tire offerings made fatbikes commercially available in local bike shops worldwide.[7] The Pugsley bikes also featured the offset wheel and frame build.
Other early versions of the fatbike were normal mountain bikes equipped with SnowCat rims, created by Simon Rakower of All-Weather Sports in Fairbanks, Alaska, in the early 1990s;[8] or with multiple tires seated on two or three standard rims that had been welded or pinned together.[9] Rakower was involved with technical support aspects of the Iditabike (later IditaSport) race, which started in 1987. Since 2002 the race continued on the same trail under the name Iditarod Trail Invitational (ITI). Rakower started hand making extra wide rims for participants by welding two rims together and cutting off the middle ridge known as the snowcat rims 44 mm (1.7 in). S. Rakower produced those rims from 1991 through 1999. Many riders on the Iditarod Trail used a Geax tire with the snow cat rim. Enthusiasts would cut and sew tire-carcasses together to maximize the size of the tire and utilize all the available space between the seat stays and chain stays; this tire and rim combination would maximize the bicycle's footprint, increasing flotation on winter trails. Soon after, Rakower decided to design a 44 mm (1.7 in) rim from scratch and had it produced. SnowCats revolutionized winter cycling, as they could be fitted to nearly any commercially available mountain bike.

Surly Bikes released the Pugsley frame in 2005 and began producing Large Marge 65 mm (2.6 in) rims and Endomorph 3.8-inch (97 mm) tires in 2006.[11] The Pugsley frame, rim, and tire offering made fatbikes commercially available in local bike shops worldwide. The Pugsley bikes also featured the offset wheel and frame build. Fatback Bikes came online in 2007 adding the carbon Corvus fatbike. Another Alaskan brand 9:zero:7 joined in 2010 also offering a carbon fatbike. Other bike manufacturers have also entered the fatbike market recently including Trek, with the Farley, Salsa with the Beargrease and Mukluk, and Specialized with the Fatboy and On=One with the Fatty. Others followed since 2014 Rocky Mountain, Felt, Kona, Pivot and many more. Since 2014, Dorel Sports has utilized their Mongoose brand to make fatbikes even more accessible to the general public, with models such as the Beast, Dolomite, Hitch, and Malus selling for around $250, considerably less than their higher-priced predecessors.
Events

As the popularity of fatbikes has expanded,[12][13][14] fatbike specific events (races, race series, tours, and festivals) have emerged. Examples include the Snow Bike Festival,[15][16] the annual Global Fatbike Summit[17] (since 2012),[18] the Fatbike Birkie race[19] which is part of the Great Lakes Fatbike Series (2014–2015 season: 8 races held across 3 states),[20][21] the US Open Fatbike Beach Championships (inaugural, 2015),[22] the USA Cycling Fat Bike National Championship (inaugural, 2015),[23][24] the Ontario-based Substance Projects OnFatbikeSeries (OFBS), the 45Nrth Fatbike Triple Crown race series[25] and the UK Fatbike Championships (inaugural, 2013).[26][27]
The Iditarod Trail Invitational (formerly known as Iditabike and Iditasport Extreme and Iditasport Impossible) race in Alaska has grown into an international event offering an extreme 130-mile (210 km), 350-mile (560 km) and 1,000-mile (1,600 km) distances. The event spurred the creation of many other winter ultra events in the United States, Canada and Europe that are accepted qualifiers to get into this Invitational.
A number of extreme expeditions have also been made on fatbikes. In December 2012 Eric Larsen attempted to ride a fatbike to the South Pole, but made it only a quarter of the way before he had to turn around.[28] Maria Leijerstam became the first to cycle to the South Pole, across the South Pole Traverse road on a tricycle with fatbike tires.[29] On 21 January 2014, Daniel P. Burton became the first person to ride a bike across Antarctica to the South Pole, starting at Hercules Inlet and biking 1,247 km (775 mi) to the South Pole on a carbon fiber Borealis Yampa fatbike[30] with 4.8 in (120 mm) wide tires.[31][32]
Popular fatbiking destinations are predominantly found in the northern latitudes of the United States, Canada, and some Nordic countries.

A Quick History of Fat Tire Biking
Time to put on some FAT! The fat tire bike, sometimes known as a snow bike, is the newest trend in mountain biking. When you swing a leg over a fat bike, you won't be able to quit smiling and laughing. These bizarre-looking machines not only prolong a cyclist's season (and escape the dreaded trainer!). Used to simplify challenging summer singletrack, sand rides on beaches, and rough rides along river banks in addition to winter snow riding. Let's ride fat bikes together!
A DEFINITION:
A fat bike is an off-road bicycle with enormous tires that are often 3.8 inches or larger and rims that are 2.6 inches or wider. These tires are made for low pressure so that riders can navigate soft, unstable terrain like snow, sand, bogs, and mud. To provide a smooth ride over challenging obstacles, the broad tires can be inflated to pressures as low as 5 psi.
THE FIRST FAT BIKES:
The first contemporary versions of fat bikes were not created until the 1980s, when three guys on separate sides of the globe were inspired. Fat bikes have been around since the early 20th century.
Steve Baker of Icicle Bicycles need a bicycle that could travel through Alaska's snowy landscape. He started it by welding two rims together and attaching two tires side by side to create a double-wide tire measuring 4.4" wide before experimenting with special parts and configurations intended to generate a big contact patch of tire on snow. The first fat bike was created when he pieced together a frame to accommodate the wheels!
Simon Rowaker, an additional Alaskan, was inspired by Baker's concept and created the Snowcat, a rim that is 1.7" (44mm) broad. As the largest manufacturing rim available at the time, this gained the most popularity in the early 1990s and was utilized by many adventure riders.
Ray Molina, an adventure cyclist, tour leader, and frame maker, was also scouting out new terrain in southern New Mexico at roughly the same time. In order to create the initial 88mm (3.2") wide rim and the 3.5" Chevron tire, Ray used two Snowcat rims that he had previously welded together while riding sand dunes and arroyos. To accommodate the new apparatus, he created a number of frames, and testing was done at the Samalayuca sand dunes in Chihuahua, Mexico. The advantages of the extra-wide tires and rims changed the game. Molina produced Remolina rims and had a sand bike available for purchase by 1999.
The first Iditabike, introduced in 1987, required riders to go 200 miles through the backwoods of Alaska on terrain that ranged from soft snow, glare ice, and liquid water overflow to rideable frozen crust. The racers walked A LOT with their bikes, which led to a spike in equipment development for the next year.
Mike Curiak of Colorado won the Iditasport Impossible race to Nome in 2000 by pushing and riding his bike more than 1,000 miles in just over 15 days, breaking the previous record by six days. He rode a custom Willits frame built by Wes Williams in Colorado, built with Remolino rims and 3.0" tires. This achievement may have served as the best fat bike proof of concept.
FAT BIKES FOR EVERYONE:
The Surly Pugsley was the one factor that increased the fat bike's accessibility. The 3.7" Endomorph tire and 2.6" wide Large Marge rims were features of the 2005 Purple Beast. The Pugsley introduced fat bikes to neighborhood bike shops all over the world. Distributed widely through Quality Bicycle Parts (QBP), "the public" could now purchase their very own fat bike. Riders assembled the frame and fork that were shipped as a kit using standard mountain bike parts.
A number of additional businesses entered the market not long after the Pugsley's popularity became clear. The Fatback bike firm of Anchorage, Alaska introduced ultra-wide hubs (165mm, then 170mm, now 190mm) and rims (70mm and 90mm) in 2007, enabling more float with less weight.
Complete fat bikes were introduced by Surly and Salsa in 2010, which led to a further increase in sales and accessibility. The momentum grew even stronger.
FAT BIKES TODAY:
Modern fat bikes can glide through terrain that "normal" mountain bikes couldn't handle thanks to their lightweight wheels and tires, front and rear suspension, trail-based design, and high-end components.
These formerly unknown novelty are now being produced for the general public by numerous small and large manufacturers, such as Trek with the Farley, Salsa with the Beargrease and Mukluk, Specialized with the Fatboy, and On-One with the Fatty. Rocky Mountain, Felt, Kona, Pivot, and numerous other brands came next. You may find the lengthy list at www.fat-bike.com.
If you weren't from Alaska, it wasn't immediately obvious what the Surly Pugsley was for when it was first introduced in 2005. Most people had the opinion that a fat bike wasn't necessary unless you simply intended to ride in the snow. The idea that fat bikes are NOT simply for snow and can travel where no bike has gone before and where all bikes have gone wasn't realized until a few years later when other manufacturers began making their own lines of fat bikes.
