1-speed is if you absolutely desire the simplicity of maintenance and design. I've never tried a Brompton 1-speed but I doubt the distinct lack of practicality is worth the savings. I would go so far as to say only get the 1-speed once you've owned a Brompton before and know exactly what you're getting into.
Also, getting a 2-speed or 3-speed opens up the possibility of an easy upgrade to 6-speed if you ever feel any desire to tour or go longer distances.
Hmm seems I made a mistake.

"The 3 speed cannot be easily/cheaply converted into a 6 speed as it is a different hub so your expensive 3-speed hub is not needed and has to be put aside."
Also note the 1-speed:
- Pros - the simplest, lightest, arguably the most efficient gearing, is a single freewheel gear, for the purist you know exactly what this choice means.
IMO by your emphasis on simplicity and flatness, a 2-speed is going to serve your needs just fine, plus you have a somewhat less messy upgrade to a 6-speed if you ever feel the need to. As it differs from person to person, it makes sense to get that till you have experience and some knowledge of Brompton gearings before picking up a 1 or 3-speed.
I started with a 6-speed in mountain-less Singapore, which served my needs just fine, but I'm now experimenting with weight-weenie alternatives to find a perfect compromise (for me) between weight and gearing and cost.
