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.
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.
"The Voytek is not your average fat-tire machine; it’s a bike designed to be built for many different intended uses. The Voytek can be trans-formed into a plus-sized hardtail with a suspension fork and a dropper post, or it can be ridden as a fat bike with the narrowest Q-factor on the market."
Mountain Bike Action Magazine
"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."
"If a 4-season rider asked me what single bike to buy for year round enjoyment, the Voytek would be top of my list."
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.
"I feel pretty safe in saying that yes, this joyful warrior is for you. Mountain biking? It’s a riot. Bikepacking? You’re good to go. Casual fat biking? It’ll be the easiest bike to toss in your buddy’s truck. Fat bike racing? Considering how incredibly stiff — not to mention light — the frame is, racing might be this bike’s calling."
"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?"
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.
The Voytek can run a wide range of wheel sizes: 27.5" or 29" plus MTB tires to 26" x 4.6" fat tires.
AND SO MUCH MORE ...
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.
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.
The EPS molded carbon frame of the Voytek was designed to accept internally routed dropper seat posts.
