Quick Summary
The Bell Bicycle Inner Tube is a 20" inner tube made for 20" x 1.75-2.125" tires. It uses a Schrader valve with cap, and the listed fit is aimed at kids' bikes and BMX.
If you are choosing between tubes, the main check is tire size and valve type. This tube is sized for a narrow range of 20" tires, so the fit needs to match your wheel and tire setup.

What to Compare Before Buying
- Wheel size: This tube is for 20" wheels, so it should be matched to the wheel size on the bike.
- Tire width: The stated range is 20" x 1.75-2.125". Compare that with the tire marking on the bike.
- Valve type: This model uses a Schrader valve. Make sure the pump head and rim opening match that valve style.

Before You Decide
Confirm the 20" wheel size, the 1.75-2.125" tire range, and the Schrader valve before choosing an offer. If those three points do not match the bike, a different tube size or valve style is the better choice.
