Surly ECR 29+
$1,900.00
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 is 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 29+ sizes have two water bottle mounts and one set 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.

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.

$1,900.00

Cannondale F-Si Carbon 5
$2,300.00
Cannondale's best XC hardtail just got better. If going really, really fast on dirt in lycra is your cup o' tea, nothing lets you top 'em on the climbs and drop 'em on the descents like the F-Si. The F-Si Carbon 4 features Cannondale's BallisTec Carbon frame with stiffness-enhancing Si offset. The RockShox Reba fork offers 100mm of travel to smooth your way to speed and control. WTB STX i23 TCS wheels deliver on strength and light weight, while the Schwalbe Racing Ray tires fly over hardpack and dig into sketchy corners. SRAM serves up 12 wide-ranging speeds, and gets it power through a stiff TruVativ crankset, resulting in efficient power transfer and crisp, precise shifting to give you the advantage on every part of the course. Shimano MT500 hydraulic disc brakes provide reliable braking power when you need it, so you can carry more speed and brake at the last possible second, and Cannondale's cockpit components and Fabric Scoop saddle keep you in control and race-ready.
Surly Pugsley
$1,900.00
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.

Up front, it features a 130mm travel suspension fork, and the overall geometry has been tuned and developed to maximize its performance on rugged trails.
All-City Electric Queen
$1,999.00

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.

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.
Giant Reign SX 1
$3,990.00
