If my top speed on the Dahon on a flat road with no wind is 25 mph, how fast can I go on a decent road bike?
1) 20 mph headwind will slow anyone down, so don't think drop bars are a panacea. You'll still suffer.
2) With a good road bike, you'll probably average 2 or 3 mph faster over your Dahon D7, at least that's my experience.
3) Your top speed will be
much better with higher gearing on a road bike.
