    Fat Bikes

    Otso Cycles is based in Minnesota, USA. The only way to ride all year is to embrace the cold and snow of winter and ride a fat bike. Our fat bikes are designed to meet the performance needs of racing and the versatility required by polar expeditions.

    The original Voytek changed the world of fat bikes. It has the narrowest Q factor (pedal stance) of any fat bike in the world, which means that it rides more like a mountain bike than a fat bike. Pair that with the aggressive XC MTB influence in the geometry of the lightweight carbon frame, and you’ve got a fat bike that is ready to ride snowy singletrack at pace. The Voytek also has suspension correction for a 120mm travel fork, mounts for cargo, and a routing port for a dropper post. When the snow melts, swap out the 26” fat wheels for 29er plus wheels and keep the party going all year. Choose Voytek for fat bike racing and riding singletrack on snow or dirt.

    Voytek 2 takes what the original Voytek started and makes it even better. We overhauled the Voytek geometry to give you a fat bike that lets you go even faster with more confidence on snowy trails. The narrow Q factor provides the agile handling that you find in a mountain bike. It has adjustable geometry in the rear dropout and in the head tube so you can alter wheelbase length, head tube angle, reach, bottom bracket height. Choose the Voytek 2 for your next fat bike race.

    The Arctodus is built for exploring the winter unknown. It is a fat bike for cyclists who want to ride beyond groomed trails. We equipped the Arctodus with clearance for the biggest fat bike tires in the world (26” x 5.05”), suspension correction for a 120mm travel fork, a routing port for a dropper post, compatibility with single speed, and extra mounts for cargo. One aspect of prototype testing for the Arctodus was an expedition on snow and sea ice in Svalbard, Norway. Choose Arctodus for local exploration, racing Iditarod Trail Invitational, and polar expeditions.
