Highs
  • Lots of tire clearance and wheel/tire configurations

  • Narrow Q-factor is less of a shock than traditional fat bikes

  • No shortage of mounting points, room for their custom Revelate Designs frame bag, and options to run a rear rack

  • Lightweight, high-quality builds

  • Completely customizable thanks to Otso’s online bike builder

  • Zippy and nimble handling thanks to stiff frame and XC-inspired geo

Lows
  • Q-factor is noticeable for those sensitive to bike fit

  • Sluggish on long sustained climbs

  • Stiff carbon frame and fork take some getting used to

  • Offset fork leg mounts can be limiting

  • Complete builds start at $3,990

Mountain Flyer
Tested: Otso Voytek Trail

May 2018

Rolling up the dry trails out my back door on the Otso Voytek Trail fat bike, thoroughly enjoying the light bike as it climbed easily and handled the rocky singletrack, I crossed an arroyo. Looking up at the mountains, I decided it would be more fun to shoot straight down the arroyo back to a different trail system than tempt fate with the storm brewing above the ridgeline ahead.
