The new Otso Cycles Arctodus is an expedition-ready fat bike built around a steel frame, carbon fork, and clearance for massive 26 x 5.0″ tires. The Arctodus is designed for maximum traction and all types of terrain. Learn more here…

Otso’s flagship Voytek has been the only fat bike in the company’s lineup for nearly six years. The Voytek is positioned as a XC-inspired fat bike with a narrower-than-average Q-factor that’s equally at home as a 29+ summer mountain bike as it is as a 26″ fatbike for racing winter ultras. As of this morning, the Voytek now has a sibling: the Otso Arctodus, a fatbike named after an extinct genus of bear that inhabited North America during the Pleistocene era. The Arctodus is designed for maximum traction on any type of terrain. Read on for details.

Otso Cycles Arctodus

When compared to the Voytek, the Otso Cycles Arctodus is a totally different beast. It’s a true expedition fat bike with a Chromoly steel frame, an Anything Cage-equipped carbon fork, and clearance for the biggest 26″ and 27.5″ tires available, easily fitting 26″ x 5.05″ and 27.5″ x 4.5″ rubber.

According to Otso, it’s unique to have this much tire clearance while still being able to house a modern 12-speed drivetrain. The Arctodus also has dedicated rear rack mounts, external cable routing, thru-axles, dropper post routing, and is suspension corrected to accept a 120mm travel suspension fork.

It’s no surprise to see the Arctodus equipped with Otso’s adjustable Tuning Chip rear dropout, allowing you to change its wheelbase length by up to 20mm, raise or lower the bottom bracket height by up to 4mm, and change the head tube angle by +/- 0.2°. The rear position is designed for a more stable ride when the trails are loose and you need as much control as you can get. The front position makes it a little more playful when the snow is firm and you want to corner quicker. All in all, the Arctodus’ geometry is tuned for stability and control in soft conditions and snow, with a head tube angle of 68.5°, a 74° seat tube angle, and 94mm of trail (size medium).
