Otso Arctodus Fat Bike

The standout feature is the Tuning Chip dropout system, which lets you adjust the wheelbase, bottom bracket height, and head tube angle. This adaptability allows you to fine-tune the bike's handling for different trail conditions, whether you want more stability in deep snow or agility on technical singletrack.

Yes, the Arctodus is designed for versatility and is compatible with both 26-inch and 27.5-inch wheels. This allows you to choose the wheel size that best suits your local terrain and riding style.

The frame provides significant clearance, accommodating tires up to 26 x 5.05 inches or 27.5 x 4.5 inches. This massive footprint is essential for maintaining traction and float on soft surfaces like fresh snow or loose sand.

While steel is heavier than aluminum or carbon, the Chromoly construction provides a distinctively smooth, compliant ride quality that absorbs trail chatter better than stiffer materials. It is a deliberate choice for durability and comfort, especially during long rides in cold, harsh conditions.

The Lithic carbon fork is designed to be stiff and precise, which helps with steering accuracy. While it lacks suspension travel, the carbon material helps dampen high-frequency vibrations, and the massive volume of the fat tires provides the primary shock absorption for the front end.

The 12-speed Shimano SLX drivetrain is a reliable workhorse known for crisp, consistent shifting even when conditions get messy. It offers a wide gear range that is crucial for climbing steep, snowy trails or navigating technical terrain where finding the right cadence is key.
