Waheela & Warakin Gravel Bikes | Voytek & Arctodus Fat Bikes

What happens when a bunch of friends who happen to be both engineers and bike nerds get together for a group ride then sit down for some drinks and chat? They notice all the little things they wish their bikes had built in and then create a business just to create the bikes for which they’ve been longing.

Born and bred on the famous gravel roads of rural southern Minnesota, Otso Cycles is a brand embracing its nordic legacy and Finnish namesake. Otso is the spirit of the bear in Finnish mythology and the bikes built by the brand embrace that toughness. With bikes made for snow, dirt, sand and gravel, the Otso line is versatile and innovative.

Now with four bikes in the Otso family, you’ll love each and wonder why you don’t own them all. The Voytek is a fat bike with mountain bike capabilities. The Waheela C is a plush carbon framed all-road bike at home on the gravel but more than capable on pavement. The Warakin, available in stainless steel and titanium models, is simply a stunningly beautiful all-road bike as worthy of a showroom as it is a week-long bikepacking adventure. The Arctodus is designed for the biggest, boldest bike adventures you can imagine.


Plus and Fat-Tire Ready

Is the Otso Voytek a fat bike or a plus-sized hardtail mountain bike? Yes, it is. Created to be one of the more versatile fat bikes on the planet, the Otso Voytek can adjust to the style of riding you anticipate or the trail on the map. The carbon frame makes this about the lightest, most agile fat bike you can find.

The carbon frame gets things started with an exceptionally lightweight and agile base of operations. The real versatility, however, can be found in the rear triangle. Pick your favorite wheel size and the Voytek can roll with it. Tire clearance will rarely be an issue as you’re able to fit everything from 29 inch or 700c wheels with 4.6 inch tires to smaller 27.5, 26 or 650b wheels.

Throw on a suspension fork to take your rigid fat bike to hardtail fat-plus status and crush some trails that require a little more cushioning.

Making things even more versatile is the patented Wolf Tooth Tuning Chip on the rear dropouts. Flip the chip and you have a longer wheelbase. Flip it again and the 20mm shorter wheelbase provides a different vibe and raises the bottom bracket clearance by 4mm to help you push less snow when the powder gets deep.

Of course, it would be shameful to talk about the Otso Voytek without mentioning the Q Factor. The distance between crank arms, i.e. the Q Factor, is notoriously wide on most fat bikes. While that’s not a huge problem most of the time, you’ll end up with sore knees, hips and ankles due to the altered geometry of each pedal stroke. Over thousands of pedal strokes, that adds up. The Otso Voytek has a more narrow Q Factor so your pedal stroke geometry is much closer to that of your mountain or road bike fits.


Ready to Explore

The bigger the adventure, the more the bike will need to rise to the occasion. With clearance for the largest fat bike tires on the market, myriad cargo mounts, and a durable steel frame the Otso Arctodus is ready for an afternoon adventure, polar exploration and everything in between.

Massive tire clearance, adjustable geometry and an exploration-based design headline Otso’s do-it-all Fat Bike. There's no need to wait for the groomer, break trail on 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 rack can be attached via mounts on the seat stays. 

The Arctodus was built around a 26" x 4.8" tire for optimal handling and control on loose trails. Currently, the biggest fat tire on the market is 26" x 5.05" and Arctodus eats them like a snack with room to spare. The same goes with the 27.5" x 4.5", which is the biggest 27.5" tire currently available. Important to note is that the 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.

Even the geometry is catered for exploration, with extra trail for optimal flotation and bottom bracket height that's friendly with deep snow. 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 the Wolf Tooth GeoShift 1º and 2º Angle Headsets, effectively unlocking five head tube angles from 66.5º to 70.5º. No matter the conditions, the Arctodus has an answer.

Also noteworthy are the Arctodus’ narrow 100mm bottom bracket, compatibility with suspension forks up to 120mm of travel and a port near the bottom bracket fits a cable and housing or hydraulic hose for dropper posts that require internal frame routing. Whether you're exploring local trails or a national forest, you can trust Arctodus to keep you riding.


All Road Gravel Fun

All-road riding is all about versatility. The Otso Waheela C takes versatility to the next level with its lightweight carbon frame, primo build options and the patented Wolf Tooth Tuning Chip permitting a switched up bike geometry to best fit your riding style.

The Wolf Tooth Tuning Chip dropout system allows you to adjust the position of the rear wheel by 20mm, creating noticeably different riding experiences. With the Tuning Chip in the forward position, the wheelbase is shorter and handling is improved. Flip the Tuning Chip to the rear position and you’ve got a longer wheelbase with greater comfort and endurance for an all-day gravel ride.

Tire clearance is another big perk with the Waheela. While able to fit 29er, 700c and 650b wheels, tire clearance ranges from 54mm to 2.1 inch depending on the wheelset, you’re able to ride virtually any road you’ll run across.

Fully integrated internal cable routing along with extra mounting locations mean you’re able to carry packs, bags and water to turn your day ride into a week-long adventure off the grid. Available in the 1x or 2x build options, the Waheela C gives you the ideal frameset to build your dream bike for any occasion.


Drop Bars For Any Occasion

There’s something classic and enduring about a beautiful bike constructed out of premium metals. The Otso Warakin - available in Titanium or Stainless Steel - embraces the timeless beauty of a quality frame with modern tech to create a bike you’ll love showing off as much as you enjoy riding it.

The stainless steel and titanium frames are more than just pretty, however. The solid metal frames are strong, corrosion resistant and provide a stiff, responsive ride that gives you maximum power transfer to make each pedal stroke as rewarding as you make it.

Day trips and overnighters are natural fits for the Otso Warakin. With multiple mount options and configurations, you’re able to attach panniers, frame bags, fenders and racks to optimize the Warakin to be the perfect bike for all your off-road plans.

Of course, you’re perfectly able to use the Warakin as a daily rider around town. Designed to accommodate wheels and tires of many sizes, the Warakin can roll with 700c, 29 inch or 650b with up to 54mm or 2.1 inch tires. Swap out the rigid fork for some suspension and build yourself a lightning fast hardtail drop bar mountain bike. Pick your road, pick your tire and start pedaling.

Longer endurance rides are make more comfortable with the patented Wolf Tooth Tuning Chip dropout system. Shorter, racier or more technical rides are made faster and more responsive. The Tuning Chip gives you 20mm of wheelbase adjustment to alter your frame geometry to best suit the ride you’ve selected for the day.
