The lowest gear on a 6-speed Brompton is 33.1 gear inches and with a 44T chainring it can go to 29.1. Considering how light the bike itself is, that's very reasonable! For reference to those who are unfamiliar with gear inches... My touring bike bottoms out at 26.5 gear inches and I've ridden it thousands of km, loaded across a lot of hilly/off-road terrain. A typical road bike might have 25-30 as its lowest, and a new touring bike might get closer to 20.
