I have owned a Bike Friday New World Tourist for nearly 6 years and am VERY happy with it. I use it for loaded touring (including mountainous areas), my daily short commute to work, running errands, as well as occasional group rides. It has served me very well. I have no intention of replacing it for those purposes.
I am wondering, however, if it would make any sense for me to buy a Dahon for a couple of other purposes, namely being able to easily take it on public transport (subway) during rushhour when regular bikes are disallowed, as well as brief non-touring trips (under 4 days) when I simply don't feel like dismantling and re-building my BF two times for such a brief trip. On the couple of occasions when I have folded my BF for rushhour trains, I found it too cumbersome and awkward. I am not big and strong. I'm about 5' 6" (166 cm) and weigh under 130 lbs (under 59 kg).
Being used to a Bike Friday, would I find the ride of a Dahon too inferior to tolerate? Is it truly easy to fold & carry on public transport? Is my height compatible with having a decent fit on a one-size-fits-all Dahon? What do people pack a Dahon in if they want to put it on an airplane? Thanks for your thoughts & comments.
