Sunlite 20 × 2.00–2.25 Tube | 48 mm Schrader
This Sunlite inner tube fits 20-inch tires marked 2.00–2.25, using the ISO 406 wheel standard. Its 48 mm Schrader valve has a removable core and a smooth, straight stem. Choose it as a replacement tube or a spare after checking the size printed on your tire and the valve opening in your rim.
How to check the fit
Three details need to match: wheel diameter, tire width, and valve type. The 2.00–2.25 range is the tire width range this tube is intended to fit. ISO 406 identifies the wheel diameter standard; the familiar “20-inch” label alone is not enough because some similarly named wheel sizes use a different diameter.
Schrader is the wider, car-style valve. This tube needs a rim drilled for Schrader and a pump head that accepts it. The 48 mm stem must extend far enough above your rim for the pump to grip.

Common questions
Will this fit any 20-inch bicycle? Check the ISO diameter and tire width on the sidewall, then confirm the rim accepts a Schrader valve. Bicycle brand alone does not determine tube fit.
Is this a tire? No. It is the air-holding tube installed inside a compatible tire.
What does a removable core do? The small valve mechanism can be removed for servicing without replacing the whole tube.
