The crew from Wolf Tooth Components are getting into the bike building business, today launching Otso Cycles. The initial product line will include two bikes. The Voytek is a carbon fiber hardtail mountain bike designed around the Otso Plus-Fat concept, while the Warakin is a drop-bar steed that’s billed as a cyclocross competitor, relaxed gravel adventure bike, and everything in between.

The name Otso comes from Finnish mythology and refers to the spirit of the bear, the most important, revered, and respected animal of all. Otso is the noble king of the forest and a symbol of strength and courage. According to a company press release, the Wolf Tooth crew decided to start a bike company because they wanted bikes that did not exist.

“It sounded easy when we were first brainstorming over a couple of beers but we quickly learned that it takes a ton of work to do it right,” read the press release. “We had to become experts in many topics including carbon molding, stainless steel tube welding, investment casting, and ISO fatigue testing to name a few. Along the way we developed a new patent-pending adjustable dropout system and carbon frame design.”

The Warakin is billed as being able to take on many different forms, from cyclocross racer to relaxed gravel adventure bike to lots of things in between.

The result are two intriguing new bikes: a fat-capable bike with nimble attributes and a drop-bar bike that eschews the usual labels.

The Otso Cycles team has a five-man roster: Mike Pfeiffer (mechanical engineer, frame designer), Brendan Moore (mechanical engineer, brand manager), Dan Dittmer (mechanical engineer, creative director), Jack Hinkens (operations, stunt rider, everything else), Chris Fisher (inside sales, assembly, shipping), and Tim Krueger (consultant).Collectively the Otso team has over 100 years of riding and racing experience.

Meet the Voytek

In the midst of WWII, the Polish army discovered a stray bear cub alone in the wild. This bear, named Voytek, grew to become a valiant soldier. Voytek drank beer, smoked (or ate) cigarettes, wrestled with the troops, and even helped carry ammunition in battle. Just like the legendary bear, Otso says its Voytek bike can be playful or serious.

Voytek is a carbon fiber hardtail mountain bike designed around the Otso Plus-Fat concept with its narrow Q-factor. It is a 27.5+ or 29+ trail bike that can also accommodate up to 26×4.6” tires.

It also featuring Otso’s patent pending tuning chip rear dropout system, where the chainstay length can be adjusted from a fun and nimble 430 mm to a fast and stable 450mm.
