You’re not hanging up your wheels when the snow flies and you love the solitude of quiet winter adventures. This overlanding machine is built for you. Our 20+ year history of building fat bikes all comes together in a modern take in the Forager. The Forager is built to hold a 27.5 x 4.5’’ tire with plenty of room for icicles. Built with current fat bike standards such as 197 x 12 rear spacing, 120mm bottom bracket shell and 150 x 15 fork, this set up will stand the test of time. At the heart of the Forager is a proprietary double butted top and down tube in the largest diameters we’ve built from, giving us the strongest, stiffest and best tracking fat bike we have ever made. The Forager is not limited to just the cold surfaces, with bike packing and bike adventuring fitting right into its oversized wheel house. We’ve taken everything we’ve learned from building fat bikes for over 20 years and combined all of that knowledge into our most advanced offering in this category. The bottom line: Fresh snow, hard pack snow and deep winter adventures are at your beckon call. No surface should be left off the list with this beast of a bike. ***The large, Stanley finished Forager has been on a few test rides. Please confirm you're ok with that before ordering. FRAMESET SPECS - Head Tube: 44mm - Bottom Bracket: 120mm Threaded - Seatpost: 30.9mm - Thru-Axle Rear End Spacing: 197 x 12 - Post-Mount Disc: 160 or 180 rotor - Max Tire: 27.5 x 4.5" - Water Bottle Locations: 2 (small has 1) - Ring Capacity (single only): 30T - Derailleur hanger: Replaceable - Fork: Enve Fat Fork 150 x 15 - Chris King Matte Black headset - Matte Black seat tube collar - 3 Moots Ti Spacers 5mm, 10mm, 20mm ***************************************************************** Angry Catfish Bicycle is one of the largest Moots dealers in the country.

Exploration requires versatility, strength, and durability because it is impossible to know what lies around the bend of the snowy trail. Arctodus Ti was created for the winter unknown. It was named after Arctodus simus, an Ice Age behemoth that was the biggest bear to ever walk the Earth. As a massive bear itself, Arctodus Ti doesn’t worry about covering vast distances in changing conditions. It has a lightweight titanium frame, a large front triangle for lots of cargo, and adjustable geometry that was designed for flotation and control in deep snow. There’s a fine line between an adventure and an expedition. This is the bike to help you find it. ************************************************************** Angry Catfish's website is tied into Otso's available inventory. If you are visiting our store to view the bike, please contact us before coming, to ensure we have what you're looking for. ************************************************************** THE BIGGEST TIRE CLEARANCE We designed Arctodus around a 26” x 4.8” tire for optimal handling and control on loose trails. You’ll have a hard time finding a 26” or 27.5” fat bike tire that doesn’t fit in the Arctodus Ti frame. That’s because this bike fits the biggest fat bike tires on the market: 26” x 5.05” and 27.5” x 4.5”. In fact, Arctodus Ti is the only fat bike with this narrow of a bottom bracket to clear tires this big with a 12-speed drivetrain. We achieve this by using a 5mm offset on the rear wheel. A big bear needs big paws, after all. ADJUSTABLE GEOMETRY 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. This frame is also compatible with Wolf Tooth GeoShift 1º and 2º Angle Headsets, effectively unlocking five head tube angles from 66.5º to 70.5º. No matter the conditions, Arctodus Ti has an answer. ARCTIC PROVEN We didn’t hold back when testing Arctodus Ti prototypes. It’s not like we designed this bike to be confined to groomed trails. Arctodus Ti was made for riding dogsled routes, forest paths, and frozen fjords. The titanium frame is durable enough to meet the demands of a Polar expedition. A large front triangle can fit your trusty full frame bag, while the carbon fork has matching three-pack mounts for extra gear. There is even an option for a rear rack that can be attached via mounts on the seat stays. The adjustable geometry was developed for exploration, with extra trail for optimal stability in deep snow. Arctodus Ti feels at home in your local forest or well north of the Arctic Circle. The mushers in Svalbard seem to like it. NARROW Q FACTOR Arctodus Ti has a 100mm bottom bracket. This is 20mm 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 Ti is compatible with suspension forks that have up to 120mm of travel. A few options are available on the Custom Bike Builder. STABILITY & FLOTATION Arctodus Ti geometry was designed for optimal riding on fresh trails. The 68.5º head tube angle paired with massive tires gives Arctodus Ti more stability than other fat bikes. DROPPER COMPATIBLE A dropper post is a game changer in deep snow and technical winter riding. Arctodus Ti has ample seat tube depth for longer travel dropper posts and a routing port just above the bottom bracket.

Voytek 2 takes what the original Voytek started and makes it better. This is a fat bike that rides like a mountain bike on snowy trails. We overhauled Voytek geometry to give you a fat bike that lets you go even faster with more confidence. Voytek 2 has adjustable geometry via the patented Tuning Chip dropout system like all Otso bikes, as well as the new GeoChip head tube system that alters geometry at the front end of the bike. It has clearance for 26” x 4.6” or 27.5” x 4.5” tires, suspension correction for a suspension fork, internal cable routing, lower standover, and several more updates. When the snow melts, swap in a 29” plus wheelset to keep the party going all year. Voytek changed the world of fat bikes when we announced it in 2016. Voytek 2 is here to do it again. ************************************************************** Angry Catfish's website is tied into Otso's available inventory. If you are visiting our store to view the bike, please contact us before coming, to ensure we have what you're looking for. ************************************************************** Narrow Q factor Voytek 2 feels more like riding a mountain bike than a bike built for 26" x 4.6" tires because it has a narrow Q factor. The Q factor of a bike is the distance between the outer surfaces of your two crank-arms. The narrower the Q factor, the more natural it feels to pedal and handle the bike because it is closer to your normal biomechanics. It also allows for stronger power transfer to the pedals, more efficient pedaling, and increased overall performance. Adjustable Geometry When pairing the GeoChip head tube system with the Tuning Chip rear dropout system, Voytek 2 geometry has unprecedented adjustability. Pair a long wheelbase with a slack head tube angle for a stable ride in deep snow. Pair a short wheelbase with a steeper head tube angle for a responsive ride on packed, tacky snow. Or mix and match based on your riding style. Customize Reach and Head Tube Angle GeoChip is a new integrated system that allows you to adjust reach and head tube angle. Three sets of flip chips nest in the frame and hold the headset upper and lower cups. One set of GeoChip flip chips allows for +/- 10mm of reach adjustment, another allows for +/- 1º of head tube angle adjustment, and the third allows for +/- 2º of head tube angle adjustment. This means that you can easily adjust your reach or head tube angle at home based on the riding ahead. With two reach options for each bike due to GeoChip, Voytek 2 effectively has eight frame sizes. Tuning Chip Rear Dropout System All Otso bikes are equipped with adjustable geometry via our patented Tuning Chip rear dropout system. The Tuning Chip can adjust the wheelbase by up to 20mm, raise or lower the bottom bracket by up to 4mm, and adjust the head tube angle by +/- 0.5º. With the machined aluminum flip chip in the rear position, Voytek 2 has a longer wheelbase, lower bottom bracket, and slacker head tube angle for confidence and stability in deeper snow. Use the front position for more responsive handling on packed trails with tight turns. A middle position chip pairs the best of both worlds. Tire Clearance and Wheel Swapping Voytek 2 can fit 26” x 4.6” or 27.5" x 4.5" tires on the stock rims. A full breakdown of tire/rim pairings can be found below in the Tech Specs. To achieve this wide tire clearance with an extremely narrow bottom bracket, the rear hub has a 5mm outboard offset to prevent chain rub. Voytek 2 can also fit 29” x 3.0” tires. So when the trails are packed with snow, ride 26” x 4.0” tires, then when the snow melts and the trails turn to dirt, swap in your 29” wheelset for plus mountain bike riding. Voytek 2 was designed to accommodate multiple wheel sizes without compromising ride quality. Modern MTB Geometry Voytek 2 builds on the geometry that we pioneered with our original Voytek. We gave Voytek 2 a slacker head tube angle, steeper seat tube angle, shorter standover. This updated geometry allows you to go faster with more confidence. Suspension Correction Voytek 2 is suspension corrected. This means that you can build it with a 120mm travel suspension fork without drastically changing the geometry of the bike with a rigid fork. Dropper Compatibility Dropper post routing has a fully internal sleeve via a port behind the head tube. The Wolf Tooth Resolve Dropper Post is an option on the Voytek 2 Custom Bike Builder. Large Front Triangle A larger front triangle means that you can fit more cargo for your ride. Use this space for a custom frame bag, two bottles, or anything else that you need to carry for the ride ahead.

We've partnered with our friends at The Radavist to bring this collaboration Voytek to life. It has all of the same features as the existing Voytek, but with this special colorway. It's ready for snowy adventures and desert touring alike. A portion of all proceeds will be donated to Protect Our Winters. When describing a fat bike, you wouldn’t typically describe it as agile. That’s where the Voytek is different. 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. ***************************************************************** Angry Catfish's website is tied into Otso's available inventory. If you are visiting our store to view the bike, please contact us before coming, to ensure we have what you're looking for. ***************************************************************** 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 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. 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 plus until winter returns. The versatility of the Voytek blurs the lines of plus and fat, keeping the party going all year long. WHEELIES GALORE! The Voytek can run a wide range of wheel sizes: 27.5" or 29" plus MTB tires to 26" x 4.6" fat tires. 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.

Voytek 2 takes what the original Voytek started and makes it better. This is a fat bike that rides like a mountain bike on snowy trails. We overhauled Voytek geometry to give you a fat bike that lets you go even faster with more confidence. Voytek 2 has adjustable geometry via the patented Tuning Chip dropout system like all Otso bikes, as well as the new GeoChip head tube system that alters geometry at the front end of the bike. It has clearance for 26” x 4.6” or 27.5” x 4.5” tires, suspension correction for a suspension fork, internal cable routing, lower standover, and several more updates. When the snow melts, swap in a 29” plus wheelset to keep the party going all year. Voytek changed the world of fat bikes when we announced it in 2016. Voytek 2 is here to do it again. ************************************************************** Angry Catfish's website is tied into Otso's available inventory. If you are visiting our store to view the bike, please contact us before coming, to ensure we have what you're looking for. ************************************************************** Narrow Q factor Voytek 2 feels more like riding a mountain bike than a bike built for 26" x 4.6" tires because it has a narrow Q factor. The Q factor of a bike is the distance between the outer surfaces of your two crank-arms. The narrower the Q factor, the more natural it feels to pedal and handle the bike because it is closer to your normal biomechanics. It also allows for stronger power transfer to the pedals, more efficient pedaling, and increased overall performance. Adjustable Geometry When pairing the GeoChip head tube system with the Tuning Chip rear dropout system, Voytek 2 geometry has unprecedented adjustability. Pair a long wheelbase with a slack head tube angle for a stable ride in deep snow. Pair a short wheelbase with a steeper head tube angle for a responsive ride on packed, tacky snow. Or mix and match based on your riding style. Customize Reach and Head Tube Angle GeoChip is a new integrated system that allows you to adjust reach and head tube angle. Three sets of flip chips nest in the frame and hold the headset upper and lower cups. One set of GeoChip flip chips allows for +/- 10mm of reach adjustment, another allows for +/- 1º of head tube angle adjustment, and the third allows for +/- 2º of head tube angle adjustment. This means that you can easily adjust your reach or head tube angle at home based on the riding ahead. With two reach options for each bike due to GeoChip, Voytek 2 effectively has eight frame sizes. Tuning Chip Rear Dropout System All Otso bikes are equipped with adjustable geometry via our patented Tuning Chip rear dropout system. The Tuning Chip can adjust the wheelbase by up to 20mm, raise or lower the bottom bracket by up to 4mm, and adjust the head tube angle by +/- 0.5º. With the machined aluminum flip chip in the rear position, Voytek 2 has a longer wheelbase, lower bottom bracket, and slacker head tube angle for confidence and stability in deeper snow. Use the front position for more responsive handling on packed trails with tight turns. A middle position chip pairs the best of both worlds. Tire Clearance and Wheel Swapping Voytek 2 can fit 26” x 4.6” or 27.5" x 4.5" tires on the stock rims. A full breakdown of tire/rim pairings can be found below in the Tech Specs. To achieve this wide tire clearance with an extremely narrow bottom bracket, the rear hub has a 5mm outboard offset to prevent chain rub. Voytek 2 can also fit 29” x 3.0” tires. So when the trails are packed with snow, ride 26” x 4.0” tires, then when the snow melts and the trails turn to dirt, swap in your 29” wheelset for plus mountain bike riding. Voytek 2 was designed to accommodate multiple wheel sizes without compromising ride quality. Modern MTB Geometry Voytek 2 builds on the geometry that we pioneered with our original Voytek. We gave Voytek 2 a slacker head tube angle, steeper seat tube angle, shorter standover. This updated geometry allows you to go faster with more confidence. Suspension Correction Voytek 2 is suspension corrected. This means that you can build it with a 120mm travel suspension fork without drastically changing the geometry of the bike with a rigid fork. Dropper Compatibility Dropper post routing has a fully internal sleeve via a port behind the head tube. The Wolf Tooth Resolve Dropper Post is an option on the Voytek 2 Custom Bike Builder. Large Front Triangle A larger front triangle means that you can fit more cargo for your ride.

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. ***************************************************************** Angry Catfish's website is tied into Otso's available inventory. If you are visiting our store to view the bike, please contact us before coming, to ensure we have what you're looking for. ***************************************************************** 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.

Built for chasing both winter-ultra finish lines and backcountry campsites, Beargrease combines the efficiency of a carbon fiber frameset with the capability of multiple cargo mounts and 27.5 x 4.0" tires. Shimano's trusted SLX 1 x 12 drivetrain ties the package together with efficiency and reliability. Beargrease is designed to push the limits of the fat bike—snow, sand, and singletrack are now more accessible and more fun than ever. High-Modulus Carbon Fiber Frame This material offers improved stiffness, better vibration damping, excellent durability, and weight savings compared to other frame materials. Beargrease Geometry 440mm chainstays, longer front/center, short stems, and wide bars create room to move and add confidence while maneuvering on tight trails. Standover height is improved, allowing the addition of an X-Small frame size. This geometry results in a fat bike that rides like a trail bike. It is stable, steers well in loose conditions, and still remains nimble and agile despite the massive wheels and tires. A low bottom bracket height is also key, keeping the rider's center of gravity low, and making dabbing, dismounting, and remounting easier. 27.5 x 4.0" Wheel & Tire Size Beargrease rolls on 27.5 x 3.8" wheels and tires. For groomed snow or dirt, the increase in diameter provides increased rollover, a longer contact patch, and the flotation of a 4.0" tire without added rolling resistance. Kingpin Deluxe Fork Featuring a full carbon design, the Kingpin Deluxe Fork is lightweight and durable, and features an amazing array of accessory bosses to help you make the most of your Beargrease fat bike: - Dual sets of Three-Pack bosses on each leg accept bottle cages or our Anything Cage accessory - Lowrider mounts work with our Down Under front rack for a traditional touring setup - Internal dynamo hub wire routing keeps the front end clean for those upgrading to dyno hubs - 150 x 15mm thru-axle design boosts stiffness and aids in solid tracking on the trail

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. ***************************************************************** Angry Catfish's website is tied into Otso's available inventory. If you are visiting our store to view the bike, please contact us before coming, to ensure we have what you're looking for. ***************************************************************** 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.
