    The Radavist x Otso Cycles Collaboration Voytek


    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.

    Protect Our Winters

    Voytek was designed for riding all year, but it's SO much fun riding on snowy trails. Unfortunately, winters here in Minnesota are getting shorter and more unpredictable. That's why we're donating a portion of every sale of this bike to an organization that can save our favorite season. Protect Our Winters helps outdoor-lovers like us protect the places, seasons, and activities that we love from climate change. This is a team of athletes, scientists, creatives, and business leaders driving the policies needed to reach climate goals and guarantee snow for future generations.

    "The Voytek is the next step in the evolution of the fat bike and Otso gave this platform a chance, delivering one of the most versatile bikes on the market. If you want the familiar feel of a mountain bike with the ability to traverse a variety of terrain, in all weather, then it’s a top contender. The lightweight carbon chassis is as beautiful as it is a joy to ride ... It’s a no-brainer for a big, burly tour in the backcountry."

    John Watson, The Radavist

    "My first impressions of the Voytek are very, very positive. Not only have they designed in some features that should offer big advantages for some riders (like the narrow Q-factor) but they have also developed a very well thought out design with high quality construction."

    "Wide Q factor is something that fat bikers have had to live with as tires started to get wider and wider, but now that I’ve had the taste of something narrower that still fits relatively wide tires, I’m not sure I can go back."

    Bike Rumor

    "If a 4-season rider asked me what single bike to buy for year round enjoyment, the Voytek would be top of my list."

    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.

    "The Voytek is not a rebranded frameset found in a Chinese blank product catalog. It’s been designed from the ground up and it shows. Making a fat bike that looks as good with 29+ wheels ain’t easy but the Voytek utilizes the massive tubing profiles to ease the eyes and has plenty of beautiful moments where the tubes transition from hard, angular lines, to organic, swooping curves."

    John Watson, The Radavist

    "Otso blurs the line between plus-size and fat. It’s a carbon-fiber hardtail built for riders who need high performance and good value, transforming between two setups: mountain bike and fat bike. It does so with no compromise and has the narrowest Q-factor of any production fat bike."


    "It’s the bike I’ve been wanting for years because, at last, your year-round rig can double as a winter fattie without compromise in either format."

    "It’s smartly designed and its details well thought-out, it’s reasonably priced, looks good, rides and handles well, and should last for ages. What’s not to like?"



    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. At the core of the Voytek is the narrowest Q-factor of any bike, which means that it handles more like a mountain bike than a fat 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.


    The Voytek can run a wide range of wheel sizes: 27.5" or 29" plus MTB tires to 26" x 4.6" fat tires.



    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.


    Voytek's suspension-corrected geometry is compatible with an Otso™ carbon rigid fork or up to 120 mm travel suspension fork.


    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.


    The EPS molded carbon frame of the Voytek was designed to accept internally routed dropper seat posts.
