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.
Often times, we forget the true essence of why we ride—to enjoy ourselves. And while many of the ear-to-ear grins come from the exploration aspect of riding, what do you do when they slowly fade as you fall into the habit of riding the same routes, day in and day out? You grab a Turbo Levo FSR Expert Carbon 6Fattie/29, and experience the smile-inspiring power to ride more trails. With it, you get the most advanced carbon technologies and engineering that come with all of our S-Works bikes, along with all of the hallmarks that our trail bikes are known for. This means that you get a 500-gram weight savings when compared to the alloy Levo, a roomy top tube for an easy fit and more control, ultra-short chainstays for nimble handling, and a low bottom bracket that makes the bike feel glued to the trail. Then comes a FACT 9m carbon chassis, with an M5 alloy rear end, and efficient and powerful Turbo technology, integrating a battery, and a new Specialized 1.3 motor that delivers 15% more power than the previous version. This also delivers a sizeable increase in efficiency, while our exclusive Rx Trail Tune at the motor smoothly and quietly brings this additional power to the pedals, making climbing the steepest of trails nearly effortless. Of course, the output is fully adjustable to conserve energy, as well, while the custom motor is also the only one on the market that features instant pedal engagement, so you get immediate power the moment you need it, and consistent torque throughout the entire cadence range. At the battery, you'll find that it's fully integrated with the down tube and easily removable for quick charging or swaps. It has a lengthy lifespan for hitting long, out of the way trails and, along with the motor, it's strategically placed for optimal weight distribution. You'll also find our Mission Control App for full control of the Turbo technology, an integrated Trail Display with all of the ride metrics you need, a Trail Remote that lets your easily switch between modes without removing your hands from the bars, and a power meter that shows exactly how much power you're putting out vs. the motor. This version also has a 150mm Öhlins RXF36 fork, SRAM Code R brakes, and a SRAM X01 one-by groupset. It also features our 6Fattie wheel system that decreases deflection and dramatically increases traction, floatation, and fun over the trail. This system also allows you the opportunity to toggle between 29-inch wheels (not included) and 6Fattie wheels, allowing the ultimate in configuration options for the trail at hand. - The Turbo Levo FSR frame is constructed with a FACT 9m carbon fiber chassis and M5 Premium Aluminum rear end, making it not only lightweight but also quite stiff and responsive. The design includes our Trail 6Fattie Geometry that includes a low bottom bracket, roomy top tube, and short chainstays. Cable routing is all internal, including that of the Command Post IR, while the battery is fully integrated in the down tube and the motor is secured by a forged brace mount. - The custom Specialized 1.3 Rx Trail-tuned motor is built for the Levo and features a 15% power increase and a significant efficiency increase compared to the Specialized 1.2 motor. This successfully places it at the top of e-bike motor technology. It has many other features that no other e-bike can touch, like instant engagement, fantastic heat management, a double freewheel design that disengages the gear box when you hit top speed, and silent, smooth, and consistent output—even at max power. - The Specialized M1-504 battery features an integrated Trail Display and ANT+/Bluetooth module with Mission Control App connectivity. It also houses 504Wh of trail-taming juice, and it's neatly integrated into the down tube.
