Which tyres does the Schwalbe tube No. 4 fit?

Schwalbe lists it for 16- and 18-inch tyres: ETRTO 37-340, 28→37-349 and 28→35-355 — which includes the 16-inch Brompton sizes. It weighs 85 g and has a 40 mm car-type (AV) valve.

Marathon Plus, Green Marathon or Kojak for my Brompton?

All three fit the 16-inch (349) Brompton wheel. The Marathon Plus has Schwalbe’s thickest protection (5 mm SmartGuard) and is the heaviest (480 g). The Green Marathon is lighter (410 g) with GreenGuard and Schwalbe’s most sustainable build. The Kojak is a fast slick at 230 g with RaceGuard, for riders who want speed over maximum protection.

Q: How well does it hold air?

Schwalbe says its standard butyl tube keeps air for an above-average time thanks to high material quality and an even wall thickness — the tube it describes as proven millions of times over.
