Len & Tamara Rubin likely would still appreciate some major investment capital
to get the all Ti framed Brompton like UFB project past the prototype
stage...

N+ 1 ?

I Have a M3L, 3 speed & Mountain drive.. It works for me.. 54,15t..

I've seen the Brompton 6 speeds, where the 44 was the big chainring
of a double.. 2nd chainring smaller..

Even a custom made clamp on front derailleur clamp-on allows one
to fit braze on FD's.. add a 3rd lever..

shifting, greasy finger FD option too..

then N+1,


I got a Bike Friday 20" wheel , Rohloff hub, disc brake..

i don't fold the Pocket Llama in daily use,
until packing for a trip, it is a Mini-Velo.. small wheel
frame , low, makes it easier to mount.. and park.
