The Hoot Ti is a premium titanium hardtail that was designed for bringing the fun to any line on the trail. The frame tubing is the 3Al/2.5V grade 9 titanium that has been an industry favorite for decades. This titanium tubing was selected because it is lightweight, lively, and emphasizes the playful Hoot Ti geometry. The bike features a custom Fox 36 Performance Elite Fork with 140mm of travel to optimize the Hoot Ti ride experience. 3-D titanium printing in the UDH rear dropouts and chainstay yoke pair with short stays for a playful ride. However you choose to ride this titanium hardtail, it’s guaranteed to be a Hoot. PLAYFUL GEOMETRY The geometry of Hoot Ti has one goal: fun. The 425mm chainstays are core to Hoot Ti because they add nimble, playful handling. The 65º head tube and 76º seat tube angles pair for a balanced riding position, while that slack head tube angle, long reach, and low bottom bracket drop of 60mm allow for confident downhill riding on aggressive trails. A shorter standover and lower top tube allow for longer travel dropper posts and more creative, playful riding without the bike getting in the way. Every detail of Hoot Ti contributes to a bike that will bring the party to any trail ride. TITANIUM FRAME The titanium tubing used in the Hoot Ti frame is the 3Al/2.5V grade 9 titanium tubing that has been an industry favorite for decades. This specific frame material was chosen because it is lightweight, lively, and responsive. These are necessary qualities for tubing that need to live up to the playful requirements of the Hoot Ti geometry. 3-D TITANIUM PRINTING The key to bringing Hoot Ti to life. 3-D titanium printing is present in the rear dropouts and the chainstay yoke. Otso engineers leveraged this technology to give Hoot Ti short 425mm chainstays while maintaining the 29” x 2.6” tire clearance. This also allowed for a hidden dropper post routing port behind the BB shell and twin cable clamps that are molded into the chainstay yoke. 3-D titanium printing is also featured at the rear UDH dropouts for a clean look and a brake mount inside the rear triangle. CUSTOM FORK Hoot Ti is built with a custom Fox 36 Performance Elite 140mm travel fork. While any 140mm fork will work with Hoot Ti, Otso engineers worked directly with Fox for this custom option because they wanted the 36mm stanchion of the Fox 36 with the 140mm travel of the Fox 34. This sturdier stanchion is better suited for aggressive, chunky trail riding. The fork features the new Grip X damper, a 44mm offset, bleeders on the fork lower, and black stanchions with black lowers for a stealth look.

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 +/.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 Biek 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.

The Otso Fenrir is a ride-anywhere bike for bikepacking races and afternoon adventures alike. It can be built with drop bars or with MTB bars and both selections are available as stock build options. A tire clearance of 29” x 2.6” or 27.5” x 2.8” keeps the Fenrir rolling on rough terrain, while extra frame and fork braze-ons are ready to carry gear for days or weeks on the trail. Like all Otso bikes, the Fenrir has adjustable geometry via the patented Tuning Chip rear dropout system that makes the bike as adaptable as its rider. VERSATILITY While all Otso bikes are known for their versatility, the Fenrir might be the most versatile yet. It was designed to accommodate drop bars with a 50mm stem or MTB bars with an 80mm stem. It can be built with gears or single speed, with a suspension fork or rigid, with a mechanical or electronic drivetrain, or with a dropper or rigid seat post. The ability to fully customize the build of the bike makes the Fenrir as versatile as its rider. FENRIR WITH DROP BARS The Fenrir was designed with the option to be built with drop bars or MTB bars. When configured with drop bars, the Fenrir rides like an extra-capable gravel bike. The relatively longer top tube means a shorter stem is needed with drop bars to align with the rider's preferred reach. It can be built with standard road/CX/gravel bars for rides on local trails or with wider bars to fit a handlebar roll loaded with lots of gear. FENRIR WITH FLAT BARS When built with MTB bars, Fenrir rides like a 90s XC bike. It's fun and lively, yet efficient and Capable with a capital C. It can handle any sketchy descent or technical climb with ease. Because the top tube is relatively short for a mountain bike, a longer stem (80-90mm) is ideal for maintaining reach. Ride it on your local singletrack or load 'er up for that backcountry tour that you've been dreaming about--you know the one. However you choose to build it, Fenrir will ride any road/trail on the map and carry all the gear to get you there. OPTIMIZED FOR BIKEPACKING Every last feature of Fenrir is optimized for bikepacking. The stainless steel frame is strong, comfortable, and surprisingly light weight. It can be built with flat bars or drop bars depending on your affinity for large handlebar rolls. Single speed is an option for folks who like simplicity while touring. It has extra mounts on the frame and fork for hauling all the gear you'll need for days (or weeks) on the trail. The frame and fork can clear 29" x 2.6" or 27.5" x 2.8" tires for trails that are especially gnarly. No matter your destination and how long it takes to get there, Fenrir is ready. SINGLE SPEED All metal Otso bikes have the option to be built single speed or with gears. Fenrir is included in that group because it has a small notch on the rear dropout near the Tuning Chip. If you build your Fenrir with gears, but want to convert to single speed later on, there is a single speed Tuning Chip available ready to order alongside other accessories. There's no wrong way to build your Fenrir. SO MANY MOUNTS A bikepacking bike needs to be able to carry all the gear for days or weeks on the trail. Fenrir has mounts for bottles, fenders, and racks. The Enve fork also has three-pack mounts on either side for sharing the load. CAPABLE GEOMETRY Pick a trail on the map and ride it. Fenrir has the endurance of a gravel bike, with the stability of a mountain bike. Above all, it is Capable with a capital C so you can stay the course and reach your destination. DROPPER FRIENDLY A small port near the bottom of the seat tube allows for the cable routing of a dropper post. If you don't ride with a dropper, you probably won't even notice the port. AMPLE CLEARANCE Tires need to meet demands of the trail for traction, stability, and comfort. Fenrir can ride up to 29" x 2.6" or 27.5" x 2.8" tires.

The Waheela C is a carbon-framed drop bar bike with adjustable geometry, unrivaled ride quality, and enormous tire clearance for 700c x 54mm, 650b x 54mm, or 29" x 2.1" tires. It has extra frame and fork mounting points for bottles and racks, easily accessible internal cable routing options, compatibility for 1x or 2x electronic or mechanical drivetrains, and the ability to run a dropper post. No matter the road ahead (or under the tire), the Waheela C is ready. GIANT TIRE CLEARANCE Gravel comes in all shapes and sizes, from the packed limestone of Southeast Minnesota to the chunky roads of the Flint Hills of Kansas. The Waheela C is equipped with tire clearance to handle the terrain of your next race. Where most gravel bikes can fit 650b x 50mm but only 40mm with bigger wheels, the Waheela C keeps on rolling, with space for 700c x 54mm tires. It'll run 700c x 35mm when the roads are tacky and tidy, 700c x 42mm when there's a bit more uncertainty, 700c x 54mm when the gravel road turns to ATV trails, and anything in between. The Waheela C can also fit 29" x 2.1", 27.5" x 2.1", or 650b x 54mm if 700c isn't really your thing. In short, the Waheela C is ready for the road ahead. ADJUSTABLE GEOMETRY Like all Otso bikes, the Waheela C sports our patented Tuning Chip rear dropout system, which allows you to change the length of your wheelbase and the height of your bottom bracket. Put the Tuning Chip in the back position to get the stability and comfort of a longer wheelbase for a full day of riding gravel. Switch to the front position to get the agile handling and responsiveness required by your next CX race. And the middle position? That's the best of both worlds. The adjustable geometry of the Waheela C allows you to ride any road or any trail without needing to switch bikes. UNRIVALED RIDE QUALITY Our proprietary Waheela geometry was developed by our engineers for stability, confidence, and comfort on rough terrain. Where many gravel bikes put extra weight on the front wheel, the Waheela C centers the rider over both wheels. This makes for a more stable ride while allowing the compliant rear triangle to come into play and absorb the bumps of a gravel road. Meanwhile, the lightweight EPS molded carbon frame adds responsiveness and readiness for a sprint up that next hill. After a long day on the saddle, you'll find yourself adding a healthy amount of miles to tomorrow's ride. EXTRA MOUNTING POINTS Waheela C features fork bottle bosses, extra down tube mounting points (6 total), as well as top tube gas tank mounting points. Numerous braze-ons allow Waheela C to accommodate water bottles, fenders, racks, frame bags, and more. DETAILS THAT MATTER Internal brake and shifter routing with sleeves, carbon access door under the bottom bracket for easier routing, front and rear thru-axle, and threaded bottom bracket for reliable, easy service. This also allows you to run that dropper post you've been dreaming about. COMPATIBLE WITH 1X OR 2X Waheela C is 1x and 2x compatible with mechanical and electronic drivetrains. It's also fully compatible with both Shimano Di2 and SRAM eTap AXS, in case you don't want to take advantage of internal routing options. QUALITY ASSURED Designed by the Otso engineering team, Waheela C frames are manufactured in one of the premier carbon fiber factories in Taiwan and come with a 5-year limited warranty. All bikes are inspected and assembled at our headquarters in Minneapolis, MN USA.

The Warakin Ti is an efficient, responsive, sprightly titanium bike that can handle any road in any weather. Using the progressive geometry of its Warakin Stainless predecessor, the Warakin Ti pairs unrivaled ride quality with the superior quality of titanium. It's a lightweight, durable, lively machine that will carry the rider to where they choose to go, while enjoying every pedal stroke along the way. SUPERIOR TITANIUM The 3Al/2.5V B338 grade 9 titanium that we use for the Warakin Ti is the same titanium that has been a bicycle industry favorite for decades, and with good reason. Equal parts science and magic, titanium is durable, lightweight, lively, corrosion resistant, and timeless. The tubing is seamless, butted, clean, and strong. It's because of the superior quality of titanium that we chose this material to lend to our heralded Warakin geometry as a bike that will endure the roughest roads in the harshest conditions and tell the stories for decades to come. EXTRA TIRE CLEARANCE If a bike is meant to ride any road in any condition, it needs to fit tires and wheels that will get you to and from your destination, while handling every bump along the way. The massive tire clearance of the Warakin Ti was built with this in mind. It'll fit 29" x 2.1" for that road that doesn't actually appear on the map, just as easily as 650b x 50mm for windy forest trails, or 700c x 35mm (or 700c x 50mm if you want a little extra) for your next gravel race. Because a frame that can last forever needs to have the ability to adapt to whatever the road (and the future) may bring. VERSATILITY Like all Otso bikes, the Warakin Ti sports our patented Tuning Chip rear dropout system, which allows the rider to lengthen or shorten the wheelbase by up to 20mm and raise or lower the bottom bracket by up to 4mm. For chunky gravel on remote roads, the longer wheelbase of the rear position is set for stability and comfort. For a quick spin around town or the CX course, the front position makes for snappy handling and agile control. The middle position? That's the best of both worlds. The Tuning Chip rear dropout system was designed because the bike should be just as versatile as its rider. TOP QUALITY Designed by the Otso engineering team, Warakin Ti frames are built by top fabricators in Taiwan and come with a five-year limited warranty. All bikes and frames are inspected and assembled at our headquarters in Minneapolis, MN USA. PROGRESSIVE GEOMETRY The progressive geometry of the Warakin Ti takes a page from the cross-country MTB playbook. Increased top tube length and a shorter stem maintain stack and reach while providing a lively ‘can-do’ attitude on rougher terrain. EXTRA MOUNTING OPTIONS Numerous braze-ons accommodate three bottles, fenders, racks, cable routing clamps, frame bags, and more. Mix in the Wolf Tooth B-RAD System to even further increase on-bike storage options. SUSPENSION-READY The geometry of the Warakin Ti includes an axle-to-crown measurement of 420mm, which allows for a shorter suspension fork.

Voytek changes the fat bike game. It is fast, lightweight, agile, and can handle even the sharpest turns of your local single-track 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 single-track 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, whereas 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 the bottom bracket height by up to 4mm and the head tube angle by +/.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.

The Enve fork also has three-pack mounts on either side for sharing the load. CAPABLE GEOMETRY Pick a trail on the map and ride it. Fenrir has the endurance of a gravel bike, with the stability of a mountain bike. Above all, it is Capable with a capital C so you can stay the course and reach your destination. DROPPER FRIENDLY A small port near the bottom of the seat tube allows for the cable routing of a dropper post. If you don't ride with a dropper, you probably won't even notice the port. AMPLE CLEARANCE Tires need to meet demands of the trail for traction, stability, and comfort. Fenrir can ride up to 29" x 2.6" or 27.5" x 2.8" tires.

The Waheela C is a carbon-framed drop bar bike with an adjustable geometry, unrivaled ride quality, and enormous tire clearance for 700c x 54mm, 650b x 54mm, or 29" x 2.1" tires. It has extra frame and fork mounting points for bottles and racks, easily accessible internal cable routing options, compatibility for 1x or 2x electronic or mechanical drivetrains, and the ability to run a dropper post. No matter the road ahead (or under tire), the Waheela C is ready. GIANT TIRE CLEARANCE Gravel comes in all shapes and sizes, from the packed limestone of Southeast Minnesota to the chunky roads of the Flint Hills of Kansas. The Waheela C is equipped with tire clearance to handle the terrrain of your next race. Where most gravel bikes can fit 650b x 50mm but only 40mm with bigger wheels, the Waheela C keeps on rolling, with space for 700c x 54mm tires. It'll run 700c x 35mm when the roads are tacky and tidy, 700c x 42mm when there's a bit more uncertainty, 700c x 54mm when the gravel road turns to ATV trails, and anything in between. The Waheela C can also fit 29" x 2.1", 27.5" x 2.1", or 650b x 54mm if 700c isn't really your thing. In short, the Waheela C is ready for the road ahead. ADJUSTABLE GEOMETRY Like all Otso bikes, the Waheela C sports our patented Tuning Chip rear dropout system, which allows you to change the length of your wheelbase and height of your bottom bracket. Put the Tuning Chip in the back position to get the stability and comfort of a longer wheelbase for a full day of riding gravel. Switch to the front position to get the agile handling and responsiveness required by your next CX race. And the middle position? That's the best of both worlds. The adjustable geometry of the Waheela C allows you to ride any road or any trail without needing to switch bikes. UNRIVALED RIDE QUALITY Our proprietary Waheela geometry was developed by our engineers for stability, confidence, and comfort on rough terrain. Where many gravel bikes put extra weight on the front wheel, the Waheela C centers the rider over both wheels. This makes for a more stable ride while allowing the compliant rear triangle to come into play and absorb the bumps of a gravel road. Meanwhile, the lightweight EPS molded carbon frame adds responsiveness and readiness for a sprint up that next hill. After a long day on the saddle, you'll find yourself adding a healthy amount of miles to tomorrow's ride. EXTRA MOUNTING POINTS Waheela C features fork bottle bosses, extra down tube mounting points (6 total), as well as top tube gas tank mounting points. Numerous braze-ons allow Waheela C to accommodate water bottles, fenders, racks, frame bags, and more. DETAILS THAT MATTER Internal brake and shifter routing with sleeves, carbon access door under bottom bracket for easier routing, front and rear thru-axle, and threaded bottom bracket for reliable, easy service. This also allows you to run that dropper post you've been dreaming about. COMPATIBLE WITH 1X OR 2X Waheela C is 1x and 2x compatible with mechanical and electronic drivetrains. It's also fully compatible with both Shimano Di2 and SRAM eTap AXS, in case you don't want to take advantage of internal routing options. QUALITY ASSURED Designed by the Otso engineering team, Waheela C frames are manufactured in one of the premiere carbon fiber factories in Taiwan and come with a 5 year limited warranty. All bikes are inspected and assembled at our headquarters in Minneapolis, MN USA.

Our original all-road bike. The Warakin Stainless was one of the first bikes we built when we created Otso in 2016. It's been such a hit over the years that we haven't changed the geometry one bit. Stainless steel has a ride quality that is familiar, yet surprising—smooth like steel, lively like titanium. The Warakin Stainless is ready for your next century, three-day bikepacking trip, or afternoon group ride. STAINLESS STEEL The supple and smooth ride quality of steel meets the corrosion resistance and lively feel of titanium. Stainless steel is lighter than you think, loads of fun, and ready for your next full day on the saddle. It's a frame material that is as unique and seldom used as it is versatile and excellent for multiple types of riding. TIRE CLEARANCE 700c? Check! 650b? Double check! 29er? Triple check! Warakin Stainless has massive tire clearance because no two roads are the same. The Warakin Stainless has clearance for 700c x 51mm, 650b x 51mm, or 29" x 2.1" tires. Race gravel with 700c x 38mm semi-slicks, then swap in 29" x 2.1" for that bikepacking trip with gnarly trails without needing to ride a different bike. TUNING CHIP™ The Tuning Chip rear dropout system allows for adjustable bike geometry by changing the wheelbase by up to 20mm, bottom bracket height by up to 4mm, and head tube angle by 0.2º. This means you can easily switch between a bike with the responsive, agile handling of a shorter wheelbase and a bike with the confidence and stability of a longer wheelbase just by flipping the Tuning Chip. Use the back position for stability and confidence with its longer wheelbase, lower bottom bracket, and slack head tube angle. The front position is ideal for winding singletrack or the CX course with its shorter wheelbase, higher bottom bracket, and steeper head tube angle. The center position is the best of both worlds. TOP PERFORMER Unparalleled ride quality results from the combination of stainless steel and carefully thought out frame geometry. The Warakin Stainless was designed by our engineers in Minnesota and manufactured by top steel frame fabricators in Taiwan. PROGRESSIVE GEOMETRY Warakin’s progressive geometry takes a page from the cross-country MTB playbook. Increased top tube length and a shorter stem maintain stack and reach while providing a lively ‘can-do’ attitude on rougher terrain. DROPPER FRIENDLY A small port near the bottom of the seat tube allows for the cable routing of a dropper post. If you don't ride with a dropper, you probably won't even notice the port. FOR THE LONG HAUL Numerous frame braze-ons allow Warakin to accommodate cable routing clamps, three water bottles, fenders, racks, frame bags, and more. Three braze-ons on either side of the fork allow for additional storage.

The Otso Fenrir is a ride-anywhere bike for bikepacking races and afternoon adventures alike. It can be built with drop bars or with MTB bars and both selections are available as stock build options. A tire clearance of 29” x 2.6” or 27.5” x 2.8” keeps the Fenrir rolling on rough terrain, while extra frame and fork braze-ons are ready to carry gear for days or weeks on the trail. Like all Otso bikes, the Fenrir has adjustable geometry via the patented Tuning Chip rear dropout system that makes the bike as adaptable as its rider. VERSATILITY While all Otso bikes are known for their versatility, the Fenrir might be the most versatile yet. It was designed to accommodate drop bars with a 50mm stem or MTB bars with an 80mm stem. It can be built with gears or single speed, with a suspension fork or rigid, with a mechanical or electronic drivetrain, or with a dropper or rigid seat post. The ability to fully customize the build of the bike makes the Fenrir as versatile as its rider. FENRIR WITH DROP BARS The Fenrir was designed with the option to be built with drop bars or MTB bars. When configured with drop bars, the Fenrir rides like an extra-capable gravel bike. The relatively longer top tube means a shorter stem is needed with drop bars to align with the rider's preferred reach. It can be built with standard road/CX/gravel bars for rides on local trails or with wider bars to fit a handlebar roll loaded with lots of gear. FENRIR WITH FLAT BARS When built with MTB bars, Fenrir rides like a 90s XC bike. It's fun and lively, yet efficient and Capable with a capital C. It can handle any sketchy descent or technical climb with ease. Because the top tube is relatively short for a mountain bike, a longer stem (80-90mm) is ideal for maintaining reach. Ride it on your local singletrack or load 'er up for that backcountry tour that you've been dreaming about--you know the one. However you choose to build it, Fenrir will ride any road/trail on the map and carry all the gear to get you there. OPTIMIZED FOR BIKEPACKING Every last feature of Fenrir is optimized for bikepacking. The stainless steel frame is strong, comfortable, and surprisingly light weight. It can be built with flat bars or drop bars depending on your affinity for large handlebar rolls. Single speed is an option for folks who like simplicity while touring. It has extra mounts on the frame and fork for hauling all the gear you'll need for days (or weeks) on the trail. The frame and fork can clear 29" x 2.6" or 27.5" x 2.8" tires for trails that are especially gnarly. No matter your destination and how long it takes to get there, Fenrir is ready. SINGLE SPEED All metal Otso bikes have the option to be built single speed or with gears. Fenrir is included in that group because it has a small notch on the rear dropout near the Tuning Chip. If you build your Fenrir with gears, but want to convert to single speed later on, there is a single speed Tuning Chip available ready to order alongside other accessories. There's no wrong way to build your Fenrir. SO MANY MOUNTS A bikepacking bike needs to be able to carry all the gear for days or weeks on the trail. Fenrir has mounts for bottles, fenders, and racks.

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, whereas 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 the bottom bracket height by up to 4mm and the head tube angle by +/.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.

The Hoot Ti is a premium titanium hardtail that was designed for bringing the fun to any line on the trail. The frame tubing is the 3Al/2.5V grade 9 titanium that has been an industry favorite for decades. This titanium tubing was selected because it is lightweight, lively, and emphasizes the playful Hoot Ti geometry. The bike features a custom Fox 36 Performance Elite Fork with 140mm of travel to optimize the Hoot Ti ride experience. 3-D titanium printing in the UDH rear dropouts and chainstay yoke pair with short stays for a playful ride. However you choose to ride this titanium hardtail, it’s guaranteed to be a Hoot. PLAYFUL GEOMETRY The geometry of Hoot Ti has one goal: fun. The 425mm chainstays are core to Hoot Ti because they add nimble, playful handling. The 65º head tube and 76º seat tube angles pair for a balanced riding position, while that slack head tube angle, long reach, and low bottom bracket drop of 60mm allow for confident downhill riding on aggressive trails. A shorter standover and lower top tube allow for longer travel dropper posts and more creative, playful riding without the bike getting in the way. Every detail of Hoot Ti contributes to a bike that will bring the party to any trail ride. TITANIUM FRAME The titanium tubing used in the Hoot Ti frame is the 3Al/2.5V grade 9 titanium tubing that has been an industry favorite for decades. This specific frame material was chosen because it is lightweight, lively, and responsive. These are necessary qualities for tubing that need to live up to the playful requirements of the Hoot Ti geometry. 3-D TITANIUM PRINTING The key to bringing Hoot Ti to life. 3-D titanium printing is present in the rear dropouts and the chainstay yoke. Otso engineers leveraged this technology to give Hoot Ti short 425mm chainstays while maintaining the 29” x 2.6” tire clearance. This also allowed for a hidden dropper post routing port behind the BB shell and twin cable clamps that are molded into the chainstay yoke. 3-D titanium printing is also featured at the rear UDH dropouts for a clean look and a brake mount inside the rear triangle. CUSTOM FORK Hoot Ti is built with a custom Fox 36 Performance Elite 140mm travel fork. While any 140mm fork will work with Hoot Ti, Otso engineers worked directly with Fox for this custom option because they wanted the 36mm stanchion of the Fox 36 with the 140mm travel of the Fox 34. This sturdier stanchion is better suited for aggressive, chunky trail riding. The fork features the new Grip X damper, a 44mm offset, bleeders on the fork lower, and black stanchions with black lowers for a stealth look.

The Warakin Ti is an efficient, responsive, sprightly titanium bike that can handle any road in any weather. Using the progressive geometry of its Warakin Stainless predecessor, the Warakin Ti pairs unrivaled ride quality with the superior quality of titanium. It's a lightweight, durable, lively machine that will carry the rider to where they choose to go while enjoying every pedal stroke along the way. SUPERIOR TITANIUM The 3Al/2.5V B338 grade 9 titanium that we use for the Warakin Ti is the same titanium that has been a bicycle industry favorite for decades, and with good reason. Equal parts science and magic, titanium is durable, lightweight, lively, corrosion-resistant, and timeless. The tubing is seamless, butted, clean, and strong. It's because of the superior quality of titanium that we chose this material to lend to our heralded Warakin geometry as a bike that will endure the roughest roads in the harshest conditions and tell the stories for decades to come. EXTRA TIRE CLEARANCE If a bike is meant to ride any road in any condition, it needs to fit tires and wheels that will get you to and from your destination, while handling every bump along the way. The massive tire clearance of the Warakin Ti was built with this in mind. It'll fit 29" x 2.1" for that road that doesn't actually appear on the map, just as easily as 650b x 50mm for windy forest trails, or 700c x 35mm (or 700c x 50mm if you want a little extra) for your next gravel race. Because a frame that can last forever needs to have the ability to adapt to whatever the road (and the future) may bring. VERSATILITY Like all Otso bikes, the Warakin Ti sports our patented Tuning Chip rear dropout system, which allows the rider to lengthen or shorten the wheelbase by up to 20mm and raise or lower the bottom bracket by up to 4mm. For chunky gravel on remote roads, the longer wheelbase of the rear position is set for stability and comfort. For a quick spin around town or the CX course, the front position makes for snappy handling and agile control. The middle position? That's the best of both worlds. The Tuning Chip rear dropout system was designed because the bike should be just as versatile as its rider. TOP QUALITY Designed by the Otso engineering team, Warakin Ti frames are built by top fabricators in Taiwan and come with a five-year limited warranty. All bikes and frames are inspected and assembled at our headquarters in Minneapolis, MN USA. PROGRESSIVE GEOMETRY The progressive geometry of the Warakin Ti takes a page from the cross-country MTB playbook. Increased top tube length and a shorter stem maintain stack and reach while providing a lively ‘can-do’ attitude on rougher terrain. EXTRA MOUNTING OPTIONS Numerous braze-ons accommodate three bottles, fenders, racks, cable routing clamps, frame bags, and more. Mix in the Wolf Tooth B-RAD System to even further increase on-bike storage options. SUSPENSION-READY The geometry of the Warakin Ti includes an axle-to-crown measurement of 420mm, which allows for a shorter suspension fork.

Voytek changes the fat bike game. It is fast, lightweight, agile, and can handle even the sharpest turns of your local single-track 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 single-track 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, whereas 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 the bottom bracket height by up to 4mm and the head tube angle by +/.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.

Versatility Meets Performance The Waheela C is a carbon-framed drop bar bike with an adjustable geometry, unrivaled ride quality, and enormous tire clearance for 700c x 54mm, 650b x 54mm, or 29" x 2.1" tires. It has extra mounting points for bottles and racks, easily accessible internal cable routing options, compatibility for 1x or 2x electronic or mechanical drivetrains, and the ability to run a dropper post. No matter the road ahead (or under tire), the Waheela C is ready. GIANT TIRE CLEARANCE Gravel comes in all shapes and sizes, from the packed limestone of Southeast Minnesota to the chunky roads of the Flint Hills of Kansas. The Waheela C is equipped with tire clearance to handle the terrrain of your next race. Where most gravel bikes can fit 650b x 50mm but only 40mm with bigger wheels, the Waheela C keeps on rolling, with space for 700c x 54mm tires. It'll run 700c x 35mm when the roads are tacky and tidy, 700c x 42mm when there's a bit more uncertainty, 700c x 54mm when the gravel road turns to ATV trails, and anything in between. The Waheela C can also fit 29" x 2.1", 27.5" x 2.1", or 650b x 54mm if 700c isn't really your thing. In short, the Waheela C is ready for the road ahead. ADJUSTABLE GEOMETRY Like all Otso bikes, the Waheela C sports our patented Tuning Chip rear dropout system, which allows you to change the length of your wheelbase and height of your bottom bracket. Put the Tuning Chip in the back position to get the stability and comfort of a longer wheelbase for a full day of riding gravel. Switch to the front position to get the agile handling and responsiveness required by your next CX race. And the middle position? That's the best of both worlds. The adjustable geometry of the Waheela C allows you to ride any road or any trail without needing to switch bikes. UNRIVALED RIDE QUALITY Our proprietary Waheela geometry was developed by our engineers for stability, confidence, and comfort on rough terrain. Where many gravel bikes put extra weight on the front wheel, the Waheela C centers the rider over both wheels. This makes for a more stable ride while allowing the compliant rear triangle to come into play and absorb the bumps of a gravel road. Meanwhile, the lightweight EPS molded carbon frame adds responsiveness and readiness for a sprint up that next hill. After a long day on the saddle, you'll find yourself adding a healthy amount of miles to tomorrow's ride.

The Warakin is a versatile steel all-road bike that will carry its rider to any destination. It is designed for multi-surface rides, overnighters, gravel races, and commuting. Frame features include adjustable geometry; lots of mounts for cargo, racks, and fenders; clearance for 50mm tires; suspension-corrected geometry to run a suspension fork; and can be built with gears or single speed. No matter your riding plans, the Warakin will meet your needs for the road ahead. THE COMFORT OF STEEL The Warakin frame is made of Otso custom-butted 4130 chromoly tubing. This steel has a classic, comfortable quality and pairs with the Warakin progressive geometry for a stable, smooth ride. 4130 chromoly is known to be durable and reliable, which makes it a strong option for light touring and afternoon rides alike. MULTI-SURFACE RIDING If you want one bike that can join afternoon group rides, gravel races, overnighters, and daily commutes, the Warakin is for you. The progressive geometry, generous tire clearance, cargo and rack mounts, and smooth steel frame allow the Warakin to adapt to many types of riding. This bike has been a favorite here at Otso HQ where a 20-mile ride could include 10 miles of pavement, eight miles of gravel, and two miles of flowy singletrack for good measure. ADJUSTABLE GEOMETRY The Tuning Chip rear dropout system allows the rider to lengthen or shorten the wheelbase by up to 20mm, raise or lower the bottom bracket by 4mm, and change the head tube angle by +/- 0.5º. For chunky gravel on remote roads, the longer wheelbase of the rear Tuning Chip position is set for stability and comfort. For a quick spin around town or the CX course, the front position makes for snappy handling and agile control. A middle position is also available, which covers the best of both worlds. TIRE CLEARANCE If a bike is meant to ride any road in any condition, it needs to fit tires and wheels that will get the rider to and from their destination while handling every bump along the way. The Warakin will fit 700c x 50mm tires for minimum maintenance roads, just as easily as 650b x 50mm for forest trails, 700c x 35mm for your next gravel ride, or anything in between.

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.

Our original all-road bike. The Warakin Stainless was one of the first bikes we built when we created Otso in 2016. It's been such a hit over the years that we haven't changed the geometry one bit. Stainless steel has a ride quality that is familiar, yet surprising—smooth like steel, lively like titanium. The Warakin Stainless is ready for your next century, three-day bike-packing trip, or afternoon group ride. STAINLESS STEEL The supple and smooth ride quality of steel meets the corrosion resistance and lively feel of titanium. Stainless steel is lighter than you think, loads of fun, and ready for your next full day on the saddle. It's a frame material that is as unique and seldom used as it is versatile and excellent for multiple types of riding. TIRE CLEARANCE 700c? Check! 650b? Double check! 29er? Triple check! Warakin Stainless has massive tire clearance because no two roads are the same. The Warakin Stainless has clearance for 700c x 51mm, 650b x 51mm, or 29" x 2.1" tires. Race gravel with 700c x 38mm semi-slicks, then swaps in 29" x 2.1" for that bike-packing trip with gnarly trails without needing to ride a different bike. TUNING CHIP™ The Tuning Chip rear dropout system allows for adjustable bike geometry by changing the wheelbase by up to 20mm, bottom bracket height by up to 4mm, and head tube angle by 0.2º. This means you can easily switch between a bike with the responsive, agile handling of a shorter wheelbase and a bike with the confidence and stability of a longer wheelbase just by flipping the Tuning Chip. Use the back position for stability and confidence with its longer wheelbase, lower bottom bracket, and slack head tube angle. The front position is ideal for winding singletrack or the CX course with its shorter wheelbase, higher bottom bracket, and steeper head tube angle. The center position is the best of both worlds. TOP PERFORMER Unparalleled ride quality results from the combination of stainless steel and carefully thought-out frame geometry. The Warakin Stainless was designed by our engineers in Minnesota and manufactured by top steel frame fabricators in Taiwan. PROGRESSIVE GEOMETRY Warakin’s progressive geometry takes a page from the cross-country MTB playbook. Increased top tube length and a shorter stem maintain stack and reach while providing a lively ‘can-do’ attitude on rougher terrain. DROPPER FRIENDLY A small port near the bottom of the seat tube allows for the cable routing of a dropper post. If you don't ride with a dropper, you probably won't even notice the port. FOR THE LONG HAUL Numerous frame braze-ons allow Warakin to accommodate cable routing clamps, three water bottles, fenders, racks, frame bags, and more. Three braze-ons on either side of the fork allow for additional storage.
