Surly Big Fat Dummy
$3,025.00
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.

Surly Wednesday
$1,499.00
The Wednesday is the result of over a decade of Omniterra design experience distilled into one steel package. It can easily ride over or through most anything Surly's other Omniterra bikes can and then some. With Wednesday, Surly borrowed elements from some of their Trail and Touring models to create an Omniterra whip that can truly handle anything you want to attempt. Want to point it down the side of mountain? Go ahead, roll those dice. And if you make it to the bottom, you’ll be able to ride back to the top for round two. Wednesday’s geometry is spry enough to get you through techy stuff, stable enough for the fast stuff, and doesn’t feel sluggish on terrain-crawling stuff. While Wednesday is plenty confident on terrifying terrain, it also has the chops for any sort of expedition you may want to undertake. Surly gave it all the necessary braze-ons and mounts for whatever accoutrements you feel necessary in your travels. Racks? Front and rear, friend. Fenders? You got it. Bottle mounts? How does triple bottle bosses on both fork legs and the down tube, and two sets of standard mounts on the main triangle grab you? They even gave Wednesday internal routing for a dropper post and Surly Trip Guides to keep everything nice and neat and free of rat’s nests. In the dropout department, Wednesday uses a cast steel, rear-facing, slotted dropout that can exit either rearward or vertically. They’re compatible with either 10mm or 12mm axles and are spaced at 170/177mm. The Wednesday comes outfitted with trusty SRAM GX shifting components and sure-stopping Hayes MX Comp mechanical disc brakes. The Wednesday is a bruiser in a steel package, and it's prepared to barrel through whatever terrain you can think to point it towards.

Key features - Capable and stiff 130mm frame is 29" and 27.5+ compatible - Boost148/110: stronger wheels, more tire clearance, shorter stays - Exclusive suspension tech with ABP and Full Floater - Straight Shot stiffness, Knock Block frame defense
Surly Ice Cream Truck Frameset
$825.00
The Ice Cream Truck goes where most other bikes can’t. Snow, rocks, mud, sand — you name it, and chances are, someone has ridden it on an Ice Cream Truck. Don’t let that terrain-crawling ability fool you into thinking the Ice Cream Truck is slow and sluggish, though. A long top tube (best paired with a short stem) and short stays make it trail-approved and ready to rip. And with 4.8” tires on 100mm rims, “trail” is relative. Show a snowman who’s boss, ride through a sand castle — all while riding the perfect get-away vehicle. Or you can stick to riding terrain that won’t ruin a child’s day. It all starts with Surly's proprietary ED-coated 4130 CroMoly steel. ED coating provides a solid foundation for paint externally while adding a layer of corrosion protection internally. The Ice Cream Truck’s frame is symmetrically-spaced at 190mm and features Surly's MDS dropout system, so you have the option of running a 197mm thru-axle, 190mm geared or a single speed rear end. Each frameset comes with all three MDS chips so you can choose your own adventure. A 132mm wide PressFit 41 bottom bracket allowed Surly to play with the stays a bit more and move them a little further out, creating a much stiffer rear end. If you feel like swapping out the included suspension-corrected, straight blade fork, you’ll have plenty of options thanks to the Ice Cream Truck’s 44mm headtube. In a world full of uncertainties, there’s one thing you can count on: Ice Cream Truck will really take you places. At least when it comes to riding a bike — it can’t do much to help you fix the rest of your life.
Heller Barghest
$2,999.00
The beast has arrived. Barghest is built for wild and woolly backcountry action with 27.5+ terrain-clawing tires and 130mm rear travel paired to 140mm up front. The long and slack full-carbon frame puts you in the right position for getting rowdy on the trail, and features internal cable routing for a sleek look. SRAM NX drivetrain components shift through the 11-speed cassette quick and smooth, while Tektro hydraulic disc brakes keep you on track and in the flow. If the search for trail defines you, Barghest is your perfect match.
