Designed to excel in any condition
The Otso Voytek: The Voytek is not your average fat-tire machine; it’s a bike designed to be built for many different intended uses. The Voytek can be transformed into a plus-sized hardtail with a suspension fork and a dropper post, or it can be ridden as a fat bike with the narrowest Q-factor on the market.
Otso Cycles is a new bicycle company from the engineers at Wolf Tooth Components. One might ask where they got this unique name, and the founders are happy to tell you. An otso is a Finnish mythological creature, the spirit of the bear, otherwise known as the king of the forest. The founders at Otso believe that their bikes should dominate the forest in any weather condition, just like the bear—from freezing snow to hot summer days. The Voytek is a bike designed to do it all. It’s a snow-trekking fat bike in the winter and a trail-slaying plus bike when the snow melts and the trails dry out. We got our hands on the all-new Voytek in its fat bike form and decided to see for ourselves how well the engineers at Wolf Tooth could build a bike of their own.
WHO IS IT MADE FOR?
Expanded range: Our Voytek came with Wolf Tooth’s 49-tooth cassette expander, which gave our test riders low-range gearing for tackling steep climbs. In addition to the expanded rear gear, our test bike had a 32-tooth chainring and a direct-mount spider from Wolf Tooth.
The team at Wolf Tooth was tired of riding bikes strictly designed for one application, so they built the Otso Voytek, a bike they believe is equally fun whether riding in the snow or on the dirt. The Voytek is a bike with multiple personalities, capable of running a few different wheel sizes, such as fat, 27.5+ or 29+. The goal behind the Voytek was to design a rig that could blur the lines between a plus-sized bike and a fat bike.
WHAT IS IT MADE FROM?
The Voytek sets itself apart from other wheel-size-convertible fat bikes by having the narrowest Q-factor of any production fat-tire-capable bike. This makes the bike feel much more like a regular mountain bike than a fat bike with narrow tires. Otso then incorporated a tuning chip into the rear dropout so the chainstays could be adjusted from 430 millimeters to 450 millimeters. The frame can handle a rigid fork or a suspension fork with 100 millimeters or 120 millimeters of travel. The Voytek can accommodate tires up to 4.6 inches wide and has internal dropper-post routing.
WHICH COMPONENTS STAND OUT?
Our test bike had a few features that quickly caught our eye. The first component that stood out to us was Wolf Tooth’s 49-tooth cog expander in an anodized-blue color that drastically extended the gearing of our Shimano 11-speed drivetrain. Otso then matched the rear cog with an anodized-blue Camo direct-mount spider, giving our drivetrain a flashy look and a better chainline. Our Voytek had a pair of Lithic Rhyolite rims with a wide 70-millimeter outer width and a DT Swiss 350 hub. Last but not least was the lightweight carbon fork with matching graphics.
Paint-matched: The Voytek can handle a suspension fork with up to 120 millimeters of travel; however, our test bike came with a paint-matched rigid fork. The fork had ample clearance for our 4-inch-wide tires and features a thru-axle.
HOW DOES IT PERFORM?
Setup: The Voytek’s suspension comes from its large 4-inch-wide tires. Running the air pressure in these tires too high will cause the bike to bounce off every rock or obstacle it hits. We found the tires rode best on our local trails between 7 and 9 psi. Lower pressures could be used for a smoother ride but hindered our ability to quickly maneuver around corners.
Moving Out: Some of the fat bikes we have tested gave us the sensation of sitting on a horse due to the wide Q-factor. The Voytek has a very comfortable and natural feel compared to other fat bikes; however, its wide traction-grabbing tires quickly reminded us we were sitting on a fatty. The bike’s cockpit has a comfortable fit with a roomy top tube and an appropriately sized handlebar and stem.
Tuning chips: The key feature of the Otso Voytek is its adjustable rear axle, which allows riders to run different tire sizes, such as fat, 27.5+ or 29+. Riders can also use the tuning chips to adjust chainstay length.
Climbing: Many of our test riders were quite shocked at how well the Voytek climbed. In its fully rigid form, the Voytek is extremely lightweight and efficient, allowing its rider to charge up the hill out of the saddle. The bike has zero issues maintaining traction, and its low-range, 49-tooth gearing gave our test riders the ability to easily spin the cranks up any steep climb.
Cornering: Fat bikes require a unique riding style due to their glued-to-the-ground feel; however, the Voytek felt fairly quick and nimble. We attributed this to its 69-degree head tube angle and short, 16.9-inch chainstays. Our test riders found they could navigate the Voytek around corners with ease; however, a few of our test riders would have enjoyed having a dropper post so they could really push the Voytek to its limits.
Traction anywhere: The Otso, in its fat bike form, provided our riders with endless amounts of traction, thanks to its super-grippy Terrene Wazia tires. These tires featured a soft compound and large knobs that dug into the dirt really well.
Descending: If a rider is planning to hit the dirt with the Voytek, we would advise against the carbon fork and instead recommend a suspension fork. The Voytek, in its fully rigid configuration, is designed for days in the snow or mellow cross-country loops. The fat tires do an okay job of absorbing trail chatter, but all of our test riders would have liked a suspension fork while riding in the dirt. That said, however, the Voytek’s key feature is that a rider can swap out parts to adapt it to the trails he chooses to ride.
TRICKS, UPGRADES OR TIPS?
Our test bike had a solid build kit, but our local trails begged for a Voytek that was set up a little differently. The first thing we would do is add a dropper post to give the Voytek a more lively feel out on the trails. Our bike also came with Wolf Tooth’s 49-tooth cog expander, which we truly enjoyed having when tackling steep climbs. We did need to make a few small limit-screw adjustments, but afterwards, our XT drivetrain shifted flawlessly and had no trouble getting into its new big ring. Otso has a long list of upgrades and add-ons on its website, so it really comes down to how much money you would like to spend tricking out your new ride.
New brand in town: The engineers at Wolf Tooth Components founded the new bicycle company known as Otso Cycles. The goal was to make bikes that would stand out from others on the market through unique features and modern designs.
BUYING ADVICE
The Voytek is a bike designed to be customized for its intended use. We highly doubt you’ll see a row of identical-looking Voyteks at your local shop, because it’s meant to have its own personality. A rider looking to purchase a hardtail he can ride year round in the snow or on singletrack will find that Otso provides him with the perfect platform to build on. It’s just up to that rider to get creative and make this bike his or her own.
Light and efficient: The Voytek combines its lightweight carbon frame with ground-hugging tires resulting in a bike that can quickly accelerate uphill. Our testers quickly noticed that the Voytek rewards riders willing to charge out of the saddle.
