Inner Tube 20 x 1.75/1.95/2.125 with Car Valve for Electric Bicycle

Inner Tube 20 x 1.75/1.95/2.125 with Car Valve for Electric Bicycle

This inner tube is designed for electric bicycles requiring a 20-inch wheel diameter and a tyre width ranging from 1.75 to 2.125 inches. It features a robust car valve (Schrader valve) for reliable air retention and easy inflation.

Product Overview and Use

The inner tube serves as a direct replacement for worn or damaged tubes in compatible electric bicycle tyres. It is a key component for maintaining proper tyre pressure, ensuring a smooth ride, and preventing punctures. This spare part from ULIP is suitable for general servicing and repairs.

Key Characteristics

• Size Compatibility: Fits tyres marked 20 x 1.75, 20 x 1.95, or 20 x 2.125.
• Valve Type: Equipped with a car valve (Schrader valve), which is common and easily inflated with standard pumps.
• Valve Length: The valve stem measures approximately 32mm, suitable for a wide range of rim depths.
• Brand: "Black Cat Tire" is visible on the product and packaging.

Compatibility and Selection Guide

To ensure correct fitment, it is crucial to verify the exact specifications of your existing tyre and rim before ordering. The nominal wheel size alone is not sufficient. Please check the following:

• Tyre Sidewall Marking: Locate the size marking on your current tyre's sidewall. It should match one of the supported sizes: 20 x 1.75, 20 x 1.95, or 20 x 2.125.
• Valve Type: Confirm that your rim is designed for a car valve (Schrader valve). This valve type has a wider diameter than a Presta valve.
• Valve Hole Arrangement: Ensure the valve hole on your rim can accommodate a car valve and that the 32mm valve stem length is appropriate for your rim's depth.

Installation and Safety Guidance

Proper installation is essential for the longevity and safety of your inner tube. We recommend the following steps:

1. Inspect the Tyre: Before installing the new tube, thoroughly check the inside of the tyre for any sharp objects, debris, or damage that could cause a new puncture.
2. Avoid Pinch Flats: When seating the tyre bead onto the rim, ensure that the inner tube is not pinched between the tyre and the rim. Inflate the tube slightly before fully seating the tyre to help prevent this.
3. Even Seating: After installation, visually inspect the tyre to ensure it is evenly seated on the rim all the way around.
4. Inflation: Inflate the tyre to the pressure recommended by your tyre manufacturer (usually marked on the tyre sidewall). Do not overinflate.
5. Post-Installation Check: After a short ride, recheck the tyre pressure and visually inspect for any signs of air loss or uneven seating.

If you are unsure about the installation process, it is advisable to seek assistance from a qualified bicycle mechanic.
