A fat bike is a type of bicycle designed specifically for riding on soft, unstable, or rugged terrain—like snow, sand, or mud—where traditional bikes would struggle. Think of it as the off-road monster truck of the cycling world
Key features of a Fat Bike
- Ultra-Wide Tires:
Typically 3.8 to 5 inches wide, these tires provide excellent flotation and grip on loose surfaces like snow or sand. - Low Tire Pressure:
Fat bikes run at very low pressures (5–15 PSI), allowing the tires to conform to uneven terrain and absorb bumps. - Reinforced Frame Geometry:
The frames are built with wider forks and chainstays to accommodate the massive tires. They often have a slacker head tube angle for better control on rough terrain. - All-Season Versatility:
While originally designed for snow and sand, modern fat bikes are used year-round on trails, gravel, and even pavement. - Traction & Stability:
The large contact patch of the tires offers unmatched traction, making them ideal for beginners or riders tackling unpredictable terrain.
Buying and selling this type of bike can be problematic due to the width of tyres, as they don’t fit in a traditionally-sized bike box.
