Green Line 14x2.125-2.50 Inner Tube - 45° Angled Valve

Keep your commute on track with the Green Line Heavy Duty Inner Tube. Specifically engineered for electric scooters and e-bikes, this tube features a premium 45° angled valve stem. This outward-facing orientation is essential for small-diameter wheels, e aproviding easy access for air pumps and pressure gauges where standard straight valves often fail to fit.

Constructed from high-density, seamless butyl rubber, this tube is designed to maintain consistent air pressure and resist the heat buildup associated with hub motors. Whether you are repairing a flat on a Hiboy, Razor, or a generic e-bike, this versatile tube provides the durability needed for urban terrain.

Key Features:

• 45° Angled Valve: Rotated outward from the centerline for easy inflation in tight hub spaces.
• Heavy-Duty Butyl Rubber: Thicker wall construction for improved puncture resistance and air retention.
• Multi-Size Compatibility: Highly elastic compound allows this tube to fit a wide range of 10-inch and 14-inch tire profiles.
• Seamless Construction: Eliminates weak points to prevent split seams under high-load conditions.
