Electric Inner Tube

E-bike inner tubes are consumables. We produce this electric inner tube in large quantities every day. It has no fancy features-just toughness, reliability, and great value. Sizes cover 14, 16, and 18 inch, with widths of 2.125, 2.50, and 3.0, and also 3.00-10, a common motorcycle size. Wall thickness is 1.0 mm, not too thin and not too thick. Valve is TR4 straight by default, but JS87 bent is available on request. Air pressure is 30–50 PSI; we recommend around 45 PSI to prevent rim pinches.

Our factory has 16 years of experience. This electric inner tube is one of our first models, and the production process is very mature. Defect rates are low, so our price is competitive. Out of our 1 million-unit monthly capacity, this model takes a significant share. MOQ is 10,000 pieces, with the option to mix sizes. OEM is supported, and you can print your brand. Free samples are available, while custom samples take one week. Quality follows national standards, with full inspection before packing. Third-party inspections are welcome.

Warranty is 3 months. Payment terms are 30% in advance and 70% before shipment, with USD accepted. We ship DDP to your warehouse. TR4 valves work for most rims, while JS87 is for angled rims. If you sell e-bike parts, this electric inner tube is a must-stock item, reliable for daily use.
