Touring leaning
Brommy S6 and swap in of maybe a 36 44 crankset
gives you 2 ranges to use those 6 gears..

still be as small a folding space..
I own a Brommy M bar 3 speed + MD planetary reduction gear crank,
an older one.. 90's.. 2 speed crank, new, .. so climbs well .

though an NWT with the more common 406 tyre has its practical benefits. clearance for knobbys,1

I have the higher BB Pocket Llama, just got it.. nice hand made bike..

sturdy rig .. , more handle bar option's , mine :[ trekking bar] With their folding handle bar steer tube.

comes down in size, some.. not Brompton small,
but still gets in car's trunks/boots.
