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.

ECR is a plus-tired off-road touring bike designed for routes with way less pavement and a lot more trail. Our Go-To Bikepacking Bike Sometimes the only way to break the humdrum of life is with a bike ride off the beaten path. Sometimes just for a quick overnighter, sometimes a month and half fully-loaded through nine countries. ECR is our answer to those sometimes. As our flagship bikepacking rig, ECR is adaptable to frame bags for the minimalist approach, as well as racks and bags to maximize gear-hauling potential. ECR is most at home when your tour starts on dirt and gets more technical from there. - Two wheel platforms available: 27.5+ for frame sizes XS–M and 29+ for M–XL - All the accessory barnacles you could ever possibly ask for including rack and fender, multiple three-pack mounts and mid-blade. - Gnot-Boost rear spacing with Rohloff torque arm slot and Bill/Ted trailer mount - Clearance for 27.5 x 3 (XS–M) or 29 x 3 (M–XL) tires (with or without fenders)

The ECR is Surly's answer to those times when you just need to escape to the woods for a while to get away from the humdrum of life. Those familiar with this steel mule know it’s designed around plus tires, previously of the 29” variety. A fully loaded 29+ bike is an excellent way to explore and get away for a while… if you’re of a certain stature that is. For smaller riders, it poses several challenges though. And no one wants new problems when they’re in the woods trying to escape old ones. To solve this, Surly redesigned the smaller sizes of the ECR to work with 27.5+ while the larger sizes are still equipped with 29+. All you medium specimens out there get your pick of the litter as they're offering that size in both options. Other updates to the ECR include and are limited to: Gnot-Boost rear spacing and a killer new beige paint job. It retains the abundant accessory mounts that we all know and love like Surly Trip Guide for brakes and derailleurs, fender, rack, and Bill/Ted eyelets, and a Rohloff torque arm slot. The 27.5+ sizes also feature two sets of Three-Pack bosses. You’ve got lots of options to bring all your “necessities” with you and still have room for excess baggage if you’ve got it.

This allows you to pick your poison — provided your poison is having a really great time while permanently donning a maniacal grin, of course. - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles, suspension-corrected fork - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed, though) - Clearance for 29 x 2.5 or 27.5 x 3 tires

The Karate Monkey frame features updated, progressive trail geometry, a new tubeset, and Surly’s Gnot-Boost rear dropout system to support multiple drivetrain and wheel size configurations. - 100% Surly 4130 chromoly steel frame and fork; double-butted main triangle and 44mm headtube - Tubeset uses the same trumpet tubes found on Instigator 2.0 frame - Adjustable rear dropouts with 145mm Gnot-Boost spacing works with 142 x 12, 148 x 12mm, and 135mm w/ 10/12 washer - Internal dropper seatpost routing - 30.9mm seat tube ID - Clearance for 29 x 2.55 or 27.5 x 3 tires

Krampus is a dedicated 29+ trail bike that can go over, off of, or through just about anything in its path. Breaking the Mold with a 29er Bike As the first "plus" bike to hit the market, Krampus changed the way many people approach trail riding. It’s shown people the light of how high-volume, large-diameter tires can vastly improve the ride experience. It’s also done a bang-up job dispelling the myth that big tires make you slow. Krampus is kind of like the opposite of a mullet: long in the front and short in the rear. With a long toptube and compact chainstays, it takes trail-shredding abilities to the next level. A mullet may be business in the front, party in the back but Krampus makes partying its business.

"Lean back, hang on, and ride that wild horse." -Thor - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles, suspension corrected fork - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed, though) - Clearance for 29 x 3" tires

Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. Lowside is like the grownup version of the bike you rode when you were a kid and still had hopes and dreams and some semblance of ambition. It’s just as happy riding singletrack as it is parked outside your favorite drinking establishment. Lowside is a singlespeed. Singlespeeding has been a part of Surly’s DNA since day one when we launched the 1x1 Rat Ride. After a lot of Homie Fall Fests and more feats of strength than we can recall, we decided to discontinue it a couple years back. Lowside picks up right where the 1x1 left off. Some have dubbed the Lowside the ultimate pub cruiser. - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though) - Clearance for 26 x 3 or 27.5 x 2.8 tires

The Surly Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. It’s the bike you turn to when you’re not entirely sure what the night has in store. It’s the bike to grab when you want to have just as much fun riding to the trail as you do on the trail, itself. Singlespeeding is an integral part of Surly’s DNA, and the Lowside continues the tradition, by taking a simpler approach to trail riding. - 100% Surly 4130 chromoly frame, main triangle is double-butted; 1 1/8" threadless chromoly fork - Singlespeed "specific" (derailleur hanger: yes; Trip Guides: no) - Dropper post routing - Gnot-Boost rear spacing - Front and rear thru-axles - 26 x 3" or 27.5 x 2.8" tire clearance

Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. It's your BMX bike all grown up. Lowside is like the grownup version of the bike you rode when you were a kid and still had hopes and dreams and some semblance of ambition. It’s just as happy riding singletrack as it is parked outside your favorite drinking establishment. Lowside is a single speed mountain bike.

If you’re like us, your bike needs will likely change by the day, week, month or year. Ogre will get you to your job during the week, then way out of town on the weekend. It even has the chops to handle a cross-country trek or nine. It’s not sluggish on pavement or gravel and can also hold its own on singletrack. Ogre is designed to be the ultimate steel utility vehicle. It relishes in those “take-the-long-way-home-and-find-some-beverages-along-the-way” sort of commutes. You can also haul enough crap on it that you don’t even have to go home if you don’t want to. For this year, we simplified Ogre a bit. We removed the canti studs, so it is now a disc brake-only beast. Now, before you start yelling at us about how the canti studs were the only reason you were even considering buying an Ogre and now we’ve left you contemplating your very existence in this ultimately-doomed universe, hear us out. Rim brake 29er rims — like the ones that you would need to have to make use of those canti studs in the first place — are becoming increasingly harder to find. We could have given you a feature that you’d end up not really being able to use in the future but what kind of monsters do you think we are? To quench your unquenchable thirst for rim brakes, check out the Troll. As far as other updates to the frame go, that about sums it up. Ogre still has everything else you’ve come to know and love: two water bottle mounts, four sets of three-pack bosses, mid- and low-blade fork eyelets, threaded holes for racks, fenders, and trailer mounting nuts, and a Rohloff OEM2 axle plate slot. It still features horizontal-slotted dropouts with Gnot-Boost spacing, a tweaked non-suspension corrected geometry, and a beefy tire clearance. It’s still fully compatible with both 29 x 2.5” and 27.5+ tires. In the complete bike version, we’ve opted to go with a 1x drivetrain and a flat handlebar. We typically try to avoid BS cliché terms like “Do-It-All” or “Swiss Army Knife of Bikes”, so we’ll just say that Ogre can probably handle most of the ideas that are bouncing around in your head.

Off-road touring can be a zesty enterprise, but it’s not without its perils. Bicycles are simple machines that are extremely efficient, but all simple machines carry along with them the chance of breaking down. This efficiency can get you in trouble if your bike decides to break down far away from the comforts of your parent’s basement. If you’re going to ride your bicycles where no one can see, you better take gear that’s up to the task. Troll is up to the task. Our Troll was once a simple mountain bike frame with a few extras that made it nice for touring. The Troll has evolved into a frame that has been pushed deeper into the category of off-road touring. Its geometry is no longer suspension corrected, which gives it more room for a larger frame bag. We’ve also adorned this frame with our Gnot-Boost spacing, allowing you to use any mountain bike hub whether it be 135mm QR, 12 x 142mm thru-axle, or 12 x 148mm Boost hub. The chainstay yoke has been redesigned to be fully compatible with 26+ tires and the dropouts still allow you to run disc brakes, fenders, a Rohloff hub, and racks simultaneously. It also comes with more braze-ons than you thought possible – there are four triple bottle mounts on the fork alone (don’t get excited, you can only run one Anything Cage per fork leg), as well as two more triple bottle mounts on the down tube. Troll is a bike that has one purpose – and that purpose is to carry you as far away from society as possible. Man has known for eons the call of the indifferent forest. The inexorable march of time, and dumb crap like cell phones, have dulled our senses and made us afraid. Reclaim your animalistic tendencies atop Man’s greatest invention.

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
