Adriane,
I hope I don't stir up the pot...This is just my personal opinion.
At the end of the day, they are all just bikes. The best way to understand is to try them yourself on the sunday ride.
We have riders who ride Flamingo, and brompton, and Dahons and all chap par lan brands. I happen to own both models (brompton and Flamingo) and to me both are fine bikes. You can see my adventure on Flamingo and Brompton at my blog... put down the links here... for ur easy reference. See u soon for sunday rides!
