I'm a biker in the San Francisco Bay Area, looking to buy a folding bike that will be taken on BART (the subway around these parts) or Caltrain (local train) 3-4 times a week. I'm about 5'10'', 160 lbs and will be riding about 5 miles every day -- including on some hills. My wife, who is about 5'4'' will also ride the bike occasionally.
I'm trying to choose between
(a) A new Downtube Nova (20", $300):
(b) A rarely used Dahon Presto (16"?, $300):
Any thoughts or advice? I know the Presto is out of production. Was it an awesome bike, with a build quality or components good enough that I should pick it over even a new downtube? I'm unsure about the ride quality vs portability trade-off of 16" vs 20" folding bikes, so any thoughts on this would be greatly appreciated. I rode a different 16" folder today, and found it a bit twitchy and hard to get much speed on. Would a 20" be much better? And would that be worth the added pain on Bart and Caltrain of a larger bike? I've only ever owned road bikes before this, so don't know much about folding bikes.
Thanks very much!
