Once upon a time our pioneering ancestors rolled along on solid rubber tires, which were awful and painful. Thankfully, nowadays we have the pneumatic tire, a marvel of invention that makes riding infinitely better. As long as your tire is inflated that is, and the first step is good tubes.   

These 49N tubes are 16 x 1 3/8" - the perfect size for your Brompton's wheels. While not as exact in their production as the German-made Schwalbe tubes,  they're still excellent for the cyclist on a budget who wants something no-muss, no-fuss that will get them from A to Z.
