@ Spam: ah ok, thx, i was hoping there were more/clearer pics available.
As for modding, yeah i love to mod and i am not fan of the Brompton's non standardization.
But i have to agree, the easiest thing would prob. to have two bikes, one ultimate commuter" which could be a cheaper off the shelf Brompton (especially as they are fairly affordable second hand in NL rightaway) and one folder for everything else/touring.
Still, i am in no rush, guess i will see in time what end up with, for now am very happy with my 2 folder fleet.
