Otso Voytek 2 - SRAM GX

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, 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.
