I've a couple of fairly steep hills to negotiate on the way to my station, so that was a consideration. I was just about able to get up them on the 3 speed model, although I'm a bit out of form and was fairly lightly loaded.
The 2009 6-speed* Bromptons have a new wide range hub that goes from to 33" to 99.5" compared to the 47" to 84.5" range on the 3 speed.
* a 3 speed Sturmey with two cogs and rear derailleur
