EXCEL 20 × 3.0 A/V Inner Tube for Fafrees F20 – Schrader Valve

Compatibility with Fafrees F20 Model

This separate product version is intended for the Fafrees F20 model. Please check the tire marking 20 × 3.0 and the length of the Schrader valve.

The EXCEL 20x3.0 inner tube is made from durable butyl rubber, ensuring excellent air pressure retention and resistance for 20-inch electric, mountain, and folding bikes.

Compatibility and Dimension Check

The inner tube is designed for tires with dimensions of 20 x 3.0 inches. It is suitable for bike models such as ENGWE L20 3.0 Boost and ENGWE L20 3.0 Pro, as well as other bikes with the appropriate profile. Before installation, please check:

• The marking on the bike tire (20x3.0).
• The rim bore, which must match a standard automotive (Schrader / A/V) valve.
• The rim depth relative to the 33.5 mm straight valve length for unobstructed inflation.

Installation Instructions and Safety Tips

Before installation, thoroughly inspect the inside of the tire and rim and remove any sharp particles or foreign objects. Slightly inflate the inner tube with air before mounting to give it shape and avoid pinching it between the rim and the tire bead.
