The Otso Voytek is already one of our favorite fat bikes, so how do you make it better? You can start by murdering it out. Then add in an incredible build kit that adds up to a sub 23lb bike, and you have what could be one of the most ‘Ultimate’ fat bikes available.
Starting with their Voytek frameset that offers up to 4.6″ tire clearance while maintaining one of the narrowest Q-Factors available, Otso gave the Ultimate a gloss black on matte finish with a few special details like a blacked out head badge and message under the top tube.
The gloss/matte treatment continues on the fork and the seat stays for an understated look that still has plenty of detail.
To go along with the Stealth look, the bike has a blacked out parts group with a mix of components that build on the black uber carbon theme. The SRAM X01 drivetrain includes a Race Face Next SL crank, Wolf Tooth Camo System chainring and cassette extender, Magura MT8 brakes, and a high end Race Face cockpit and all of the WTC accessories.
The bike rolls on Industry Nine Big Rid 825 wheels with HED carbon rims and I9 hubs and spokes. 
Other details include a custom WTB Volt Otso saddle, and Schwalbe 26 x 4.0″ Jumbo Jim tires, though Otso says select substitutions can be made.
All together, this large frame with two B-Rad accessories on the downtube and a RockShox Reverb dropper came in at 22.82lbs. Without a dropper and the B-Rad stuff, Otso says they’ve weighed in under 22lbs.
Priced at $8,099 for the complete build shown here (no dropper post or B-Rad accessories), Voytek Ultimates should be available in October and will be sold in addition to the standard two colors.
