When do you need a 20 inch bicycle inner tube?
A bicycle inner tube is essential when your tyre has a puncture or when you want to replace it preventively for a reliable ride. This 20 inch FISCHER inner tube is specifically designed for smaller bicycles such as children's bikes, folding bikes and some BMX bikes. You need this size when your bicycle has 20 inch wheels and the current inner tube is damaged or worn.

Why choose this wide version?
This inner tube has a wide design that suits various tyre widths, from 1.5 inch to 2.125 inch. This makes it compatible with both narrow racing bicycle tyres and wider comfort or all-terrain tyres. You can therefore handle different riding styles and terrain types, from smooth city rides to light off-road use.

Car valve with 35 mm length
The car valve (also known as a Schrader valve) is robust and easy to inflate with standard car pumps and petrol station compressors. The valve length of 35 mm ensures the valve remains easily accessible, even on rims with a deeper profile. This valve type is more reliable than the thin racing valve and less susceptible to damage.

Checking compatibility
Always check the ETRTO standard on your current tyre or rim before purchasing. This inner tube fits ETRTO sizes 40-406 to 57-406, where the first number indicates the tyre width and 406 the rim diameter. If in doubt, you can also use the inch designation: this inner tube is suitable for 20 x 1.5 to 20 x 2.125 inch tyres.
