Inner tube 12 inch by Schwalbe with Schrader valve

Inner tube for 12 inch wheels with Schrader / Car type valve from Schwalbe. This is the most common size of inner tube used on pushchair / stroller pneumatic tyres.

Why choose this inner tube from Schwalbe as opposed to something cheaper?

Because not all inner tubes are the same, and here's why: Schwalbe test all of the inner tubes that they manufacture (twice), including inflating the tube for 24 hours to ensure it doesn't lose air pressure.

Less lost air means you need to spend less time pumping up the tyre / tube.

This inner tube fits ETRTO tyre sizes as shown below:
47-203 - 12 1/2 x 1.75 inches
50-203 - 12 x 2.00 inches
54-203 - 12 x 2.10 inches
62-203 - 12 1/2 x 2 1/4 inches
