A fat bike is a type of bicycle designed with oversized tires, typically 3.8 inches or wider. These wide tires provide better traction and stability, making fat bikes ideal for riding on soft surfaces like snow, sand, and mud. They are often used for recreational riding, touring, and even racing in challenging terrains. Fat bikes usually feature a sturdy frame and a lower gear ratio to help riders navigate difficult conditions. They can be equipped with various components, such as disc brakes and suspension systems, to enhance performance and comfort. Many cyclists enjoy fat biking for its versatility and the unique experience it offers.
