lazily copied from the Dahon forums
I've been fascinated with the idea of an all-purpose, take-anywhere folder for quite some time, and I've narrowed my choices down to the Speed TR (first choice and still the favorite), Mu SL, and Speed Pro TT. Basically I've reduced my possessions to what I can carry on my back (clothes, laptop, and odds/ends essentially) and I aim to live out a go-anywhere nomadic lifestyle.
The bike I choose needs to handle long, arduous trips (hundreds of miles) on roads that can often be questionable in nature, maintain a speedy pace, and pack small enough to carry on a bus or check onto a plane. Comfort is not a variable here, but lightweight is attractive (not required).
The Speed TR is the heaviest of all of these, but it also the most fully equipped for my needs; I appreciate and would use all the accessories added to the bike (my possessions may want to spill onto the racks). I also aim to engineer some type of fixture to harness the kinetic energy for powering my electronics, but that's a crazy idea left for another topic.
The reason I like the Mu SL and Speed Pro TT is due to their much lighter weight. How appreciable would that actually be for my kind of usage? Would that lend any assistance to speed? I don't know how often I'd actually be picking up the bike. They also don't look quite as ideal for rougher roads.
Any advice here would be strongly appreciated. I by no means hold expertise in this field, just an ardent willingness to learn.
