Is Otso’s Voytek a plus MTB that can handle a 4.6″ fat tire? Or is it a fatbike that can roll on 27.5+ or 29+ wheels? The q-factor on the Voytek leads me to believe it’s a MTB frame with ample clearance for a 4.6″ fat tire. With the narrowest q-factor out of any other “fatbike” on the market because of its PF107BB spec, paired with a RaceFace Cinch crank and RF149 spindle, bringing the width to 183mm, the Voytek is designed to handle like a modern mountain bike. That’s because, with its unique Tuning Chip™ dropout system and 177×12 rear hub spacing, you can convert it to a hardtail with a dropper easily or run it as a fat bike. The options are endless.
