The CST SCOUT AT 20x4 EBIKE TYRE is a durable, high-traction fat tire engineered for 20-inch e-bikes and e-mopeds, excelling on both city streets and light off-road trails. Its robust construction and specialized tread pattern provide reliable grip and stability, particularly beneficial for heavier e-bikes, including those with cargo or passenger capabilities. This 20x4.0 tire features a blocky tread design with siping and wide channels, offering predictable control during acceleration, cornering, and braking across varied surfaces like pavement, hardpack, and light gravel. The rounded profile helps reduce rolling resistance on smoother terrain for efficient riding. An integrated puncture protection layer with reinforced casing fibers enhances durability, providing a robust shield against flats. Designed with e-bike specific needs in mind, the CST Scout is E25 rated for speeds up to 25 km/h (15 mph) and features a 60 TPI (threads per inch) casing for a balance of durability and ride quality. Its wire bead construction ensures a secure fit and reliable performance. This tire is an ideal replacement for many 20-inch fat tire commuter e-bikes, prioritizing traction, control, and longevity, making it a strong choice for daily commutes and mixed-use riding.
