Big adventures require a bike that can rise to the occasion. Arctodus is named after Arctodus simus, an Ice Age behemoth that was the largest bear to ever walk the Earth. Like its namesake, Arctodus the bike is versatile, strong, and ready to explore. It has adjustable geometry, a durable steel frame, a massive front triangle for a frame bag, lots of cargo mounts, and can clear the biggest fat bike tires on the market. Arctodus is ready for afternoon exploration, polar expeditions, and everything in between.

*****************************************************************
THE BIGGEST TIRE CLEARANCE
Arctodus was built around a 26" x 4.8" tire for optimal handling and control on loose trails. It can fit the biggest fat bike tires in the world. The biggest fat tire on the market is 26" x 5.05" and Arctodus eats them like a snack with room to spare. Same as 27.5" x 4.5", which is the biggest 27.5" tire available. Arctodus is the only bike to clear tires this big with a 12-speed drivetrain without chain interference. When a bike is created for big rides with fresh snow, it needs to fit tires that were designed for the same reason. This is a bike that prays for snow and cuts its own trail.
ONE BIKE, THREE WHEELBASE LENGTHS
A key feature in all Otso bikes is adjustable geometry and the ability to adapt the bike for the ride ahead. The patented Tuning Chip rear dropout system can change wheelbase length by up to 20mm, raise or lower the bottom bracket height by up to 4mm, and change the head tube angle by +/- 0.5º. Use the rear position when the trails are loose and you need as much control as you can get. Use the front position when the snow is firm and the trails let you take turns with a little speed. No matter the conditions, Arctodus has an answer.
DESIGNED FOR EXPLORING
There's no need to wait for the trail groomer. Arctodus was made for foot trails, forest paths, and snow-covered frozen lakes. The bombproof steel frame can withstand the demands of an expedition. A large front triangle can fit a healthy full frame bag. The carbon fork has mounts on either side for cargo. A rear frame can be attached via mounts on the seat stays and Tuning Chip hardware. Even the geometry is catered for exploration, with extra trail for optimal flotation and bottom bracket height that will ride above deeper snow. Whether you're exploring local trails or a national forest, you can trust Arctodus to keep you riding.
NARROW Q FACTOR
Arctodus has a 100mm bottom bracket. This is 30-40mm narrower than other fat bikes that have the same tire clearance. Ride with massive tires without compromising handling.
SUSPENSION CORRECT
All Otso frames feature suspension-corrected geometry. Arctodus is compatible with suspension forks that have up to 120mm of travel. A few options are available on the Custom Bike Builder.
STABILITY & FLOATATION
Arctodus geometry was designed for optimal riding on fresh trails. The 68º head tube angle paired with massive tires gives Arctodus more trail than other fat bikes. Even the BB height was selected for clearance in deep snow.
DROPPER COMPATIBLE
Snowy trails are good with dropper posts, too. A port near the bottom bracket fits a cable and housing for a cable-actuated dropper post.

Voytek changes the fat bike game. It is fast, lightweight, agile, and can handle even the sharpest turns of your local singletrack with ease. Think of it as a mountain bike that can fit fat tires with adjustable geometry. We paired a narrow pedal stance—aka Q factor—with aggressive XC race geometry to build a fat bike that can intuitively handle snowy trails like your mountain bike can handle summer singletrack without sacrificing ride quality. When the weather turns and the snow turns to dirt, swap out the 26" fat wheelset for a 29" MTB wheelset to keep the party going all year.

THE Q-FACTOR IS THE KEY
The Voytek has the narrowest Q-factor of any fat bike in the world at 183mm. With a narrow Q-factor, your weight is closer to the centerline of the bike. This is especially important when cornering because it allows for tight, responsive control—the wider Q-factor found on most fat bikes spreads out your pedals and creates a floppy, unstable feel. The Voytek frame was designed around an 83mm bottom bracket, where most fat bikes have a bottom bracket north of the 100-110mm range. With the Voytek, you don't need to compromise agile handling to ride up to 4.6" tires.
ONE BIKE, THREE WHEELBASE LENGTHS
Our Tuning Chip rear dropout is at the heart of the versatile Voytek. With a quick change in positions, the wheelbase of the Voytek can be extended or shortened by up to 20mm, which also changes bottom bracket height by up to 4mm and head tube angle by +/- 0.5º. In the forward position, you've got an aggressive, responsive Voytek for your next race. In the rear position, you've got that same intuitive handling but with added stability to make it easier to ride in deep snow or adverse terrain. In the middle, well, that's the best of both worlds.
PLUS OR FAT? FAT OR PLUS?
We're internally divided here as to whether the Voytek is a plus bike that can handle fat tires or if the Voytek is a fat bike that has the handling worthy of a plus bike. When the trails are packed with snow, we're riding 4" tires. When spring comes and the trails turn to dirt, we swap out tires and ride 29" plus until winter returns. The versatility of the Voytek blurs the lines of plus and fat, keeping the party going all year long.
MODERN GEOMETRY
Voytek's longer top tube, short chainstays—the shortest in the world for a fat bike—and slightly slacker head tube angle mean more speed and more fun.
SUSPENSION CORRECT
Voytek's suspension-corrected geometry is compatible with an Otso carbon rigid fork or up to 120 mm travel suspension fork.
COMPETITOR TESTED, ISO APPROVED
Voytek's patent-pending frame design exceeds all ISO frame safety standards and has been proven over thousands of miles of test riding, including the legendary Iditarod Invitational and Arrowhead 135 competitions.
DROPPER COMPATIBLE
The EPS molded carbon frame of the Voytek was designed to accept internally routed dropper seat posts.

Frameset + Crankset = Frankset! Voytek is a carbon fat bike with the narrowest Q-factor on the market. And since 83mm cranksets can be difficult to find, we include them with the frameset.

High-Modulus Carbon Fiber Frame
This material offers improved stiffness, better vibration damping, excellent durability, and weight savings compared to other frame materials.
Mukluk Geometry
Mukluk's geometry works extremely well in all conditions and use cases, whether it be riding groomed singletrack at your local trail, exploring a beach coastline, or embarking across the wild frozen expanses of Alaska. At its core, we use the shortest chainstay possible with a headtube angle and fork offset that place the rider's center of gravity further over the rear wheel. This location and combination of front and rear center is key to getting a fat bike that is stable, steers well in loose conditions, and still feels nimble and agile despite the massive wheels and tires. A low bottom bracket is also key to keep the rider's center of gravity low and to make dabbing, dismounting, and remounting easier.
26 x 4.6" Wheel & Tire Size
Mukluk rolls on 26 x 4.6" tires on 80mm rims. This huge tire delivers massive traction, stability, and optimum flotation on soft surfaces such as ungroomed snow or loose sand.
Kingpin Carbon Fork
Featuring carbon construction with an aluminum steerer, the Kingpin Fork is lightweight and durable, and features an amazing array of accessory bosses to help you make the most of your Mukluk:
- Two sets of Three-Pack bosses on each leg for water bottles for Anything Cages
- Lowrider mounts work with our Down Under front rack for a traditional touring setup
- Internal dynamo hub wire routing keeps the front end clean
- 150 x 15mm thru-axle design boosts stiffness and aids in solid tracking on the trail

Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out.
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. 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)
- Spec'd in alternating years with 26 x 3" or 27.5 x 2.8" tires, the Lowside remains capable of running either option

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.
