Yes, the CST Big Boat is a tube-type tire. It is designed to be used with a compatible inner tube and is not intended for tubeless setups.

The Aramid layer is integrated into the casing to provide puncture protection without significantly compromising the tire's flexibility. You get the peace of mind of a tougher tire while maintaining a smooth, stable ride on paved surfaces.

The Big Boat is optimized for pavement and urban environments. Its smooth-grooved tread pattern is designed to maximize contact with hard surfaces, so it will not provide the necessary grip or traction for loose dirt, mud, or technical off-road trails.

E-bikes are typically heavier and generate more torque than standard bicycles, which puts extra stress on tires. The Big Boat features a robust construction and a sturdy wire bead designed to handle that increased weight and power, ensuring the tire maintains its shape and durability over time.
