The Otso Voytek just received its first major update since its release back in 2016, including bigger tire clearance, triple pack mounts on the fork, new paint jobs, and updated build kits. Check out all the details here…

The Otso Voytek is quite unique among the world of fat bikes. Owing to its narrow Q-factor and XC-inspired geometry, it’s equally suited to running massive 26 x 4.0″ tires in the winter or 27.5+ or 29+ mountain bike wheels in the summer. We’ve heard of many Voytek owners racing winter events in the winter and then with a simple wheel swap and flip of the rear dropout tuning chip, running it as a mountain bike or bikepacking rig in the warmer months. The Voytek hasn’t received any major updates beyond build kits and colours since its release in 2016—until now.

While the Voytek’s geometry and demeanour haven’t changed, Otso has expanded its overall versatility with a redesigned fork, more tire clearance, and fresh build kits. The new fork has three-pack mounts on both legs for cargo cages or racks and can now clear 26 x 5.4″ tires (the frame is maxed out at 26 x 4.8″). It’s built up around a carbon frame and fork, thru-axles, hydraulic brakes, and a well-rounded, performance-oriented component list that appears to leave little to be desired.
