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.
