Sunlite Utili-T Inner Tube – 16 × 4.00–4.50 | 48 mm Schrader Valve (E-Bike Compatible)
This Sunlite Utili-T inner tube is designed for 16-inch wheels running very high-volume tires and a Schrader valve, and is commonly used on select small-wheel e-bikes and fat-tire bikes.
Built to fit ISO 305 rims, this tube is well suited for compact e-bikes, folding e-bikes, fat-tire youth bikes, and specialty small-wheel applications that use oversized 16-inch tires. The longer 48 mm Schrader valve provides easier access on wider or thicker rims and works with standard floor pumps and air compressors.
