Fat Bike Technology Never Looked So Fast

Use TŌWMAK to replace your indoor trainer during wintertime. Or storm along the coast of Lake Michigan during summertime. TŌWMAK lends itself to situations only limited by your imagination. Carve new towpath through wilderness backcountry or blaze old singletrack that hasn’t been touched in decades. TŌWMAK is exceptionally stable, powerful, and responsive, and only shreds lightly if and when you want it to.

Unphased by mother nature’s most extreme conditions, TŌWMAK delivers the durability and longevity you’d expect in a quality-made titanium bike. Add to the mix TŌWMAK’s top-end speed over relentless terrain, or the ability to plow through 8+ inches of fresh snowfall, and you have a bike that embodies BBCo.’s Ultradistance Gravel Friendly Geometry (UGFG). In other words, you can go further, faster.

Whether you’re looking to embark on a multiday bikepacking adventure or just flat-out win fat bike world championships, TŌWMAK is the ti drop-bar fat bike that delivers on all fronts. TŌWMAK is built with our Ti 150 Fat Fork – our highly lightweight and durable titanium fork that offer triple cage mounts for more storage or hydration.

For those who’ve pedaled our drop-bar fat bike, it goes without saying: TŌWMAK does anything and everything that it’s told, but better. Contact us directly to learn about TŌWMAK build options.
