Big Dummy is a long-tail cargo bike, which means that not only can you haul a serious amount of cargo, different accessories can be added to your Big Dummy frame and deck depending on what you want to carry. Being a dedicated single-piece frame, instead of an add-on to an existing bike, it's stiffer and resistant to torsional flex, which provides a better ride and longer lasting frame than long-tail add-ons. Like all Surly's frames, it's made of their size specific, 4130 CroMoly steel – a tube set engineered for cargo that sports lots of little touches that you've come to love in a Surly, like clearance for big tires and the use of common component sizes. Figure on being able to carry about 200 pounds (90kg) of cargo. The load weight, and how it's loaded, will affect the handling somewhat. Also, plan on using gears, especially as cargo weight increases. This may seem obvious, but as you get comfy with it, you will use your full range of gears as never before. The parts kit is good quality, and suitable to loaded as well as unloaded riding. It's got a 3x10 drivetrain, Avid BB7 disc brakes, quality Shimano Deore hubs, and 26x2.3" Kenda Kiniption tires. They've outfitted it with Surly-designed bags, deck, rails and Dummy Rail Collars; everything you need for the majority of stuff you might carry, like groceries, shovels, bags of charcoal or mulch, guitars, lamps, mannequins, whatever. Bags, deck, rails, and rail collars are all designed to improve on previous offerings and work together to make sure your stuff is transported with safety and stability. It's an unbending interface, which when you're carrying lots of cargo, is a good thing to have. Get creative, and get hauling. If you intend to carry a passenger on your Big 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. These are included with current Big Dummy bikes and frames, as well as available for older Big Dummy bikes and frames (compatible with all generations of Big Dummy bikes/frames). 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. If you are planning to carry a child on your Big Dummy, Surly recommends the use of a child seat. They've tested the Maxxi Yepp seat. Yepp makes an adaptor that allows their seat to mount onto Surly's deck. It works well with the Big Dummy. At this time other child seats are not recommended and will void your warranty. Surly is testing other options. For the most up to date compatibility/options, check http://www.surlybikes.com/safety Note: keep in mind Big Dummy weight limits when carrying a passenger.

The Big Easy is a longtail electric cargo bike that expands what's possible by bike. With passenger deck seating, Surly trailer integration and the option to run dual batteries, families with children, entrepreneurs with bike supported businesses and commuters who want to run more errands en route to their destination will appreciate the maximum cargo potential of Big Easy. - Condensed bike size range and dropper post routing to promote bike sharing and to accommodate more riders per frame size? - Fully tested and rated electric bike component set? - Capable of running dual batteries for extended range - Damping headset provides smooth and stable handling characteristics under heavy loads? - Equipped with the most powerful Bosch electric bike motor and largest battery available - Includes Bosch Standard 4A charger, wiring harness and brackets for additional battery

Riding with cargo is core to Surly's mission on this earth, whether you’re running a front rack and bag setup or a full-blown cargo bike and trailer. There are times, however, when even the strongest riders are limited in what they can haul, so Surly created Big Easy, their long-tail electric cargo bike. Consider it the 18-wheeler of the cargo bike world, minus the diesel fumes. When it comes to geometry, Big Easy rides and feels like a normal-length bike. It has increased stand-over height clearance and they threw in a dropper post to promote bike sharing across different-sized riders. So, whether you want to wave goodbye to the old family gas hog, upgrade your bike-supported business’s two-wheeled fleet, or simply haul more bowling balls during your daily commute, Big Easy makes doing all that, well, easy. - Full component set perfectly suited for electric cargo bikes, including four-piston Tektro brakes - Equipped with Bosch Performance CX, their most powerful drive unit - Capable of running dual batteries for extended range, if you’re into that. (All mounting hardware and wiring included.) - Damping headset provides smooth and stable handling characteristics under heavy loads - Condensed bike size range and dropper post routing to promote bike sharing and to accommodate more riders per frame size - Includes Bosch Standard 4A charger, wiring harness, and brackets for additional battery

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.

Bridge Club is a highly versatile touring bike that perfectly hits the sweet spot spanning on- and off-road excursions. All Road Touring Bike for Any Destination Bridge Club is for those multi-surface outings — planned or unplanned. We've all run out the clock on a dirt tour and had to add in some paved shortcuts. Conversely, when you’re feeling a little zesty on your next road tour, Bridge Club is ready for reroutes through the woods. Some people hear "bike touring" and immediately think of long-forgotten stretches of highway, small-town oddities, and roadside attractions. Some instantly recall desolate stretches of desert dirt roads or lush green forest trails. With Bridge Club, you can have your dessert and eat it too! - Ultra-focused on simplicity, it only has the barnacles that matter most to the discerning bike tourist - Two build kit options: Pavement (700c) and Off-Road (27.5) - Run racks and panniers, framebags, or all of the above - Disc brake-specific, single position vertical rear dropout makes it less intimidating than other bikes in the category - Clearance for 700 x 47mm tires (with or without fenders), 27.5 x 2.8 tires (27.5 x 2.6 with fenders), and 26 x 3 tires (26 x 2.8 with fenders)

When your bike touring route takes you over the river and through the woods with a quick jaunt through town for supplies, you can't beat the versatility and smooth riding characteristics of Surly's new Bridge Club. First off, it's a Surly so you know the 'Natch chromoly steel frame and fork are built to handle your entire kit and caboodle, and thanks to the typical overabundance of rack and cage provisions you can mount your gear via traditional racks and panniers, go full bikepacking-style, or mix-up your favorite combo of the two. The Bridge Club rolls on plump 27.5 x 2.4-inch WTB Riddler tires for a blend of low rolling resistance on smooth pavement and confident handling on forest trails. You can also run up to a 2.8-inch wide tire for more flotation, or swap-in a 700c wheel and tire combo if your route includes a lot of on-road riding. A dependable 2x10 drivetrain ensures you'll never run out of gears as you make the push up long climbs, and mechanical disc brakes offer worry-free performance to keep you safe no matter what the weather brings. And, thanks to fully housed cabling and front and rear fender mounts, you can splash through soggy days with a smile. A comfortable Salsa Bend flat bar and WTB Volt saddle complete this relaxed all-terrain tourer.

Cross-Check is a tough-as-nails, super-versatile road bike that performs astonishingly well on any surface. There is no such thing as one bike that can do it all, but Cross-Check comes pretty damn close. It's a dyed-in-the-wool commuter and utility rig. It was a gravel crusher long before "gravel bikes" existed. Some people have even raced cyclocross on it. Though, we don't necessarily condone that behavior. Cross-Check was the first complete bike we ever offered. Since then, people have modified them hundreds of different ways to suit their riding styles and preferences. There’s a reason that nearly every person who has ever worked for Surly has owned one. - Semi-horizontal dropouts for singlespeed compatibility and wheelbase adjustability - Gnot-Rite dropout spacing allows installation of 130 or 135mm hubs - Accommodations for front and rear racks and fenders - Clearance for 700 x 42mm tires with or without fenders

There is no such thing as one bike that can do it all, but the Cross-Check comes mighty close. It's a cyclocross bike by design, but don’t be fooled into thinking that it has only one purpose. This jack-of-all-trades will do just as well getting you across the country as it does getting you across town. At home on the road, on trails, and on gravel, the Cross-Check'll fit pretty big tires, or smaller ones if you like. It can be built as a geared bike, a singlespeed, or a fixed-gear. The Cross-Check’s frame is engineered to supply a comfortable but lively ride. The tubing is CroMoly steel, high quality, custom-drawn, and built to our specifications. It's designed to work with components of popular sizes, meaning you can find both new and old parts to hang on this frame. It will accommodate a wide range of crank types and chainring sizes. It's got accommodations for racks and fenders (front and rear) and, because of its ample tire clearance, you can outfit it to suit where and how you will use it. There's a reason the Cross-Check has remained popular after all these years. The frame is comfy, tough as nails, and super versatile. Surly continues to hear from people for whom the Cross-Check has long been their go-to bike simply because it performs so astonishingly well on any surface.

Surly's Long Haul Trucker enjoys a reputation as one of the best riding and most value-packed touring bikes out there. It's been around long enough to be tested in the real world, in all kinds of places, with all kinds of loads on all kinds of roads. Sometimes, however, a combination of load, climate and terrain demands a bit more braking performance than a standard rim-brake LHT can provide. That's where the Disc Trucker comes in. Disc Trucker is a Long Haul Trucker specifically designed for the unique forces discs impose. Surly made sure it can run discs, racks, and fenders with no jury rigging, a somewhat unique feature they've just now decided to call Simulpatibility. Most of the components on the complete bike are the same as the standard LHT; parts chosen for their balance of technical capability, durability, and value. The drivetrain uses the sort of wide gearing you will need for loaded and unloaded travel, cable operated disc brakes for their proven reliability and ease of service, and hubs that are durable and easy to maintain. You'll need to outfit it with the extras you want, like fenders and racks. Surly doesn't include that stuff because everybody's needs are different. From the casual commuter to the person who rides around the world more than once, the Disc Trucker is more than capable. It's a tool designed from the ground up to take you and a bunch of stuff just about anywhere you'd like to go. It is a tool to help you get lost and find yourself.

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 Surly's 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.

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

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?

Years ago the Karate Monkey helped start the 29-inch wheel movement and, as time's gone by, many companies ­– Surly included – have experimented with even more wheel sizes. With so many different types and sizes of tires now on the market, riders have begun to understand the effect that tire width has on overall wheel diameter, and with ample tire clearance, you can see the benefits of multiple wheel sizes all on one bike. 27+ tires have the same rolling diameter as a 29-inch wheel, yet you get all the traction and floatation benefits of extra-wide knobbies. And that's just the tires. The Karate Monkey frame has recently gotten a makeover that includes the addition of features like internal dropper post routing, a new tubeset that uses the same trumpet tubes found on Surly's Instigator 2.0, and a slight tweak in geometry that is more progressive and trail-oriented. The Karate Monkey uses a horizontal dropout with a derailleur hanger that features Gnot-Boost spacing, which gives the rider the ability to run any kind of mountain bike hub they choose. 10 x 135mm QR, 12 x 142, or 12 x 148 Boost will all work in the Karate Monkey frame. The frame uses a 44mm headtube for broad fork compatibility and is ED coated for an added layer of internal protection. If, at any point, you decide you want to throw on some skinny meats, standard 29-inch wheels and tires can be swapped in with no issue. If you want to round-house kick some trail right in the face, the Karate Monkey is your sled. - 100% Surly 4130 chromoly steel frame and fork; double-butted main triangle and 44mm headtube - Adjustable rear dropouts with 145mm Gnot-Boost spacing. Works with 142, 148 12mm thru, as well as 135mm w/ 10/12 washer - Internal dropper seatpost routing with 30.9mm seat tube ID - Clearance for 29 x 2.55 or 27.5 x 3 tires

Karate Monkey is a highly-versatile trail bike that plays the part of 29er and 27.5+ equally well. Multipurpose Hardtail Mountain Bike Karate Monkey delivers a resilient, lively ride on all sorts of gnarly terrain. Its frame is a highly-versatile canvas for whatever dirty masterpiece your brain cooks up. According to our computing machine (Thor) it can be set up in approximately 487 different configurations. Originally designed as a 29er (and the frame that helped spark the 29" wheel movement), the latest Karate Monkey is designed to perform just as admirably as a 27.5+ rig as well. 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 venerable Karate Monkey. When it comes to mountain riding, this bike brings everything you need to the experience and more. It's shod with 27.5 x 3.00 terrain-clawing Dirt Wizards for max traction on singletrack thanks to an aggressive tread pattern and cushy, wide footprint. But there's more to this agile trail runner's set of shoes — thanks to generous frame clearance, you can drop a set of 29-inch wheels in with up to a 2.50-inch tire if you desire something with less bite and similar roll-over capabilities. And, with Surly's Gnot Boost rear dropout spacing, you can comfortably run any kind of mountain bike hub: 10 x 135mm QR, 12 x 142mm, or 12 x 148mm Boost will all work in the Karate Monkey frame. Wheel choices aside, Surly built the updated Karate Monkey with a nod toward modern trail-bike geometry and includes internal dropper post routing, two or three bottle mounts (depending on size), threaded fender eyelets, and all the braze-ons you've come to expect from Surly for attaching racks, cages, and bags galore. Running gear consists of SRAMS's rock-solid NX 1x11 drivetrain with full-length external housing and Level hydraulic disc brakes for reliability when you need it most. Throw on a 140mm suspension fork and this all-rounder turns into a serious trail slayer. For what seems like a simple bike at first glance, the Karate Monkey offers much, much more. Listen to the Monkey and lose yourself in its ways.
