Pivot Cycles LES Fat Pro XT
$4,250.00 - $4,560.00
The Pivot LES Fat is the world’s most versatile big-tire machine. It's compatible with almost every wheel size available, from 26-inch to 27.5-inch Fat to 29er. The perfect wheel and tire combination? That’s always open to debate. But one thing is beyond dispute: No matter which wheel size you choose, your bike should handle great. Pivot's proprietary Swinger II dropout system guarantees that’s always the case, no matter which wheel and tire combination you use. The ingenious dropouts maintain ideal geometry via an indexed adjustment arc designed into the dropouts—the bigger the wheel and the more clearance you choose, the lower the bottom bracket. The LES Fat full carbon frame features a svelte top tube and seatstay shaping for comfort on long rides and epic adventures. The full carbon frame features leading-edge materials and Pivot's proprietary hollow-core, internal-molding process. This coveted technology enables Pivot to create an ultra-lightweight frame featuring the largest downtube in the category and a 132mm Press Fit BB for best-in-class power transfer. Additional frame details include the Cable Port System for clean and easy cable routing, three water bottle mounts, and a narrow Q-Factor for better pedaling ergonomics. The LES Fat frameset includes a Pivot-designed carbon, rigid fork that easily accommodates any wheel size with clearance to spare. This full carbon fork features 150mm dropout spacing—the same spacing as fat bike suspension forks, so you can use the same wheels with rigid and suspension forks. Looking for a bike that's ready for anything? The LES Fat is a four-season hardtail that can take you from singletrack to snow to sand with no compromises.

KHS 4 Season 5000
$3,299.00
Wherever and whenever you want to ride a bike, KHS's 5000 is as ready as you are. The heart of this wide, track-laying beast is the high-modulus MSD carbon frame that's light, gorgeous, and pairs beautifully with its carbon fork, letting you dive into corners as the nearly 5-inch wide Vee tires float over and grab snow, mud, and even hardpack. That ability comes in handy when the wide-range SRAM X7/X9 drivetrain gets you up to speed and keeps you there even when conditions get fluffy. Always reliable Hayes Prime Sport hydraulic disc brakes help keep you from disappearing into a snowdrift forever. When the snow starts flying and the wind is chilly, don some wool and bear-hug the fat.
Surly Big Fat Dummy
$3,025.00
The Big Fat Dummy is a long tail cargo bike that took a few too many doses of growth hormones. At first glance, you might say that Surly just put bigger tires on a Big Dummy. But if you said that, you'd actually be very wrong so just… don't. Think of Big Fat Dummy as more of a second or third cousin to Big Dummy rather than a brother. They share some of the same DNA and look sort of similar, but they're two very different bikes and really only interact when they both reach for the potato salad spoon at that family reunion that no one really wants to be at anyway. Now that that's out of the way, let's get down to the nitty gritty of what makes this hulking beast of a bike tick. Surly's goal with designing a cargo bike around fat tires was to create the most stable, stiff, and traction-laden ride possible while hauling a ton of stuff. Big Fat Dummy has a longer toptube and slacker headtube than its more svelt cousin giving it a nice, predictable, and stable ride. They also used thinner, lighter tubing to construct its cargo area so while it's an overall burlier bike, there's not much difference in weight. Big Fat Dummy accepts either 10mm or 12mm axles in the rear with a spacing of 190/197mm. That big ol' spacing equates to one thing: tire clearance for days. Big Fat Dummy maxes out at a massive 26 x 5.25" tire.* While that large of a tire provides the most traction and stability a bike can possibly offer, it's also a lot of rubber to push and might not be for everybody. Luckily, Big Fat Dummy is also a blast to ride with 3" tires too. It uses the same 100mm suspension-corrected fork as the Wednesday, meaning if you want to add a little squishy squishy to your ride, you can throw a Bluto on and let ‘er rip. If you intend to carry a passenger on your Big Fat Dummy, Surly requires use of their Dummy Rail Collars. These provide a secondary retention system for the rack, as well as stiffen the rack system. In addition, a stoker handlebar set up, found on tandem bicycles, is recommended as well. Make sure to check with seat post manufacturer for stoker handlebar compatibility. All Big Fat Dummy framesets and bikes ship with a Dummy deck, rails, bags, and the aforementioned Dummy Rail Collars so you can immediately start hauling cargo — human or otherwise. Big Fat Dummy is ready and willing to carry all sorts of crap — literally. It's already in use on an organic farm in Ecuador so it's likely that it's hauled some form of manure by now. *Using a 26 x 5.25" tire will cause some drivetrain limitations.

Surly Ice Cream Truck
$2,000.00
Ice Cream Truck is the bike we reach for when we don’t really know what the trail has in store. From log and root-covered ribbons of twisty singletrack to miles of powdery snow or sandy beaches, Ice Cream Truck can handle it all. Hell, you could probably even hop over a grizzly if the situation arises. Probably. While we could certainly throw out terms like "confidence-inspiring" and "traction-laden" to describe Ice Cream Truck, those phrases are mostly garbage, so we’re not going to do that. We’re not here to inspire you, and we didn’t laden it with anything. What we did do was design a monolith of a trail bike that doesn’t care what’s in front of it. - Long toptube, short seatstays, and a 68-degree headtube angle makes it tight and maneuverable on fast, technical terrain - Modern trail bike standards like stealth dropper post routing, 44mm headtube, and thru-axles - Clearance for a full 26 x 5 tire on 100mm rims

Low Center of Gravity Playful Trail Bike Sloping "low slung" front triangle design provides a low center of gravity for technical maneuvering with ease or countersink control in deep conditions.

Surly Pugsley
$1,900.00
The Surly Pugsley may be the original fat bike, but this one is far from the original. Previously a great all-around fat bike, the Pugsley has been redesigned to be an ideal off-road touring and exploration rig. Surly lengthened the chainstays 12mm for stability when loaded and so your heels float effortlessly past panniers. The tweaked rear rack mounts on the dropouts let you center your rack over the wheel, despite the offset rear triangle. Those dropouts will take a 142x12mm thru axle if that's your schtick, but this rig comes with a 135mm QR hub, snug as a bug with a pair of adapter washers. Pugsley brings back the 135mm-spaced offset fork, so you can run a front wheel with a spare cog or freewheel as a bail-out option to swap with the rear if your internally-geared hub freezes up in neutral or you smash your derailleur having too much fun. A plethora of three-pack mounts give you gear-hauling options aplenty, and a Surly Moloko Bar gives your hands damn near as many options as well, so they stay clappably happy even on your longest, story-generating adventures.

A WTB Volt Comp saddle offers a comfy perch for longer outings, so you can push your forays even deeper into the unknown.

Surly Wednesday
$1,550.00
Wednesday is a great all-around fat bike that has the soul of a trail bike and mind of a touring bike. Wednesday sits in the middle of our Trail category, but don’t let that fool you into thinking that’s its only use. With Wednesday, we borrowed elements from some of our Trail and Touring models to create a versatile fat bike that can truly handle anything you want to attempt. If you do an equal amount of off-road touring as you do hitting trails, Wednesday’s ability to play both parts equally will suit you well. Or, if you’re looking for a fat bike and don’t need the fattest tires on the market, Wednesday’s 26 x 4.6" tire clearance is just the ticket. Any day of the week’s a great day to ride a Wednesday. - Modern mountain standards: stealth dropper post routing, 44mm headtube, suspension correction, front and rear thru-axles - Full suite of useful braze-ons: front and rear racks, multiple sets of three-pack mounts, fenders - Full-forward, short chainstay position: 26 x 3.8 tires on 80mm rims; full-rearward, longer chainstay position: 26 x 4.6 tires on an 80mm rim
Surly Ice Cream Truck Frameset
$825.00
Surly's Ice Cream Truck turns up the volume on fat. With unmatched traction and float courtesy of super wide tires (up to 4.8-inches wide!), and the flickable geometry of your favorite trail bike, this fatty feels frisky, limber, and ready for action. The symmetrically spaced 190mm rear end uses Surly's Modular Dropout system for an array of rear axles choices. 197mm thru-axle? 190mm geared? Singlespeed? All equally plausible possibilities with the Ice Cream Truck. A 44mm headtube provides fork options, and the frameset ships with a suspension-corrected, 150mm fork with a 15mm thru-axle. Surly's proprietary 4130 chromoly steel and corrosion-fighting ED coating add a hefty dose of tough to this bike. Now, where do you want to ride your Ice Cream Truck?
Surly Wednesday Frameset
$650.00
Wednesday is a frame with a decade of Surly's Omniterra design experience distilled into one steel package. Wednesday can ride over the same type of pretty much anything all of their other Omniterra bikes can, but they borrowed elements from both their Trail and Touring categories to create an Omniterra ride that can truly handle anything you want to attempt. Want to point the thing down a mountain and roll those dice? Wednesday has geometry spry enough to get you through the techy stuff, stable enough for the fast stuff, and doesn’t feel sluggish when you have to ride back to the top. It also has the chops for any sort of expedition you may want to undertake. It has plenty of bottle mounts; triple bottle bosses on both fork legs and the down tube; standard bottle mounts on the seat tube and underside of the down tube; plus rack mounts on the frame and fork and fender eyelets on the dropouts, along with barrel bosses on the crown, fork legs and mid-blade, thru-blade eyelets on the fork as well. It also has internal dropper post routing and Surly Trip Guides to manage all the housing and cables on your frame with style. Wednesday also has its very own dropout design as well – a rear-facing, slotted dropout that can use either 10mm or 12mm axles and exit rearward or vertically. They’re cast steel and spaced at 170/177mm. Wednesday gives you a lot of options in the tire clearance category. In the full-forward, short chainstay position you can run 26 x 3.8? tires on 80mm rims and in the full-rearward, longer chainstay position you get the option of 26 x 4.6? tires on an 80mm rim. Wednesday is made out of Surly's own proprietary 4130 CroMoly steel and is ED coated for extra protection from the elements.
