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.
The Wednesday is the result of over a decade of fat bike design experience distilled into one steely-eyed package. With Wednesday, Surly borrowed elements from some of their Trail and Touring models to create a whip that can truly handle anything you want. The frame features trail-ready geometry, 4.6" of tire clearance, and lots of cargo carrying capabilities. - 100% Surly 4130 CroMoly steel with 44mm headtube and internal dropper post cable routing - Frame is ED Coated for increased life expectancy - 1-1/8" straight steerer fork, 4130 CroMoly - 100mm Threaded BB shell - Universal cast dropouts accommodate thru-axle or quick-release standards
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?
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.
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.
