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.
We designed Diamondback's el Oso Tres to be capable of any adventure you point it at. Of course, you might argue that a fat bike with a suspension fork is overkill, what with the high-volume/low-pressure Maxxis Minion FBF/FBR 26x4.0-inch tires already soaking up rocks and gripping Mother Earth like they were slathered in glue. Then again, we built this bike with the most remote and technical trails in mind. When you're days away from the nearest trailhead, a burly, winter-tested fork plus a reliable parts package all come in really handy. The KS E30i dropper seatpost improves maneuverability on dicey downhills. Thru-axles front and rear add stiffness for enhanced steering precision. Overkill? Heck. Yeah. Bring on the overkill. Bring on the adventure. - The 6061-T6 aluminum frame/fork with hydroformed tubes packs a punch without also packing extra weight - Manitou Mastodon Comp 100mm travel fork clears your way through the toughest terrain - Powerful Shimano SLX M7000 hydraulic disc brakes increase your control - No mountain is too steep with Raceface Aeffect cranks and Shimano 1x11-speed drivetrain components - Maxxis Minion FBF/FBR 26x4.0" tires provide gobs of traction - KS E30i dropper seatpost lets you drop that WTB Volt Race saddle and improve maneuverability on dicey downhills
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
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.
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
The fastest human alive topped out at 27 miles per hour. Fastest bear? 35 miles per hour. The takeaway? Bears are fast; particularly this bear, Diamondback's el Oso Dos. We made this fat bike quick by designing it around a rigid platform to shave pounds. Thru-axles front and rear add stiffness for enhanced steering precision. Let the gigantic tires take care of the suspension—something they do quite well. That means you can ride this bike up and over just about anything and under any conditions, including through snow, sand, or mud. Even when the weather gets bearish, el Oso Dos will keep you in the saddle. - The 6061-T6 aluminum frame/fork with hydroformed tubes packs a punch without also packing extra weight - Rear thru-axle adds stiffness - Twenty reliable gears to scale any terrain, courtesy of Shimano - Powerful TRP Slate X2 disc brakes provide control in all conditions - DB El Oso Custom air formed alloy fork rides as well as it looks. It's also plenty stiff, thanks to its 15mm thru-axle - 26x 4.5" tires are wide enough to take you places other bikes fear to tread
