Parents fixing a flat on a 14 inch kids' bike.
This Duro 14 inch inner tube suits tyres from 1.75 to 2.125 inches wide, which covers most 14 inch kids' bikes. Check the sidewall of your tyre: if it reads 14 x 1.75, 14 x 1.95, 14 x 2.125 or 47-254 to 57-254, this is the one.
It has a 32 mm Schrader valve, the same type as a car tyre, so you can pump it up at a service station or with any standard floor pump. Duro is a long-established Taiwanese tyre and tube maker.
Kids' bike tubes often fail from low pressure and pinch flats, so pump them up to the pressure printed on the tyre and check them every few weeks.

Match the ISO number on the tyre: this tube is for 254 mm bead seat (47-254 to 57-254). 14 x 1-3/8 inch tyres are 288 and need a different tube.
Fitting tip
Put a little air in the tube before fitting so it holds its shape and doesn't twist. Push the valve up into the tyre before seating the last bit of bead, then check all the way round that the tube isn't caught under the tyre before inflating fully.
