Still, I don't think that's _really_ the problem.

No, the 3 speed hub is at the back and the derailleur mounts onto it.

But the Dualdrive is more complex, so you seem to be misunderstanding
something somewhere... With the Nexus 7 if you want to change up,
change up, if you want to change down, change down. There's no "split
second decisions" you have to make at all, so I think basically it's all
a problem in your head. The point of a DD is more finely graduated
gears and a greater overall range than a hub, but it really is more
complex because you've got two independent shifting mechanisms. If it
works for you then that's Good, but for future reference don't get hung
up on hubs on their own being more complex to use, because they're not!

Lightness makes you quicker and as Dr, Moulton proved back in the 60s,
small wheels aren't nearly the problem that lots of people seem to
assume as long as you have a reasonably good surface, and "reasonably
good" certainly doesn't require a billiard table.

Dahon are Far Eastern, and are the largest manufacturer of folding bikes
in the world.

Sadly, I guess that this is a clue towards sorting Behemoth. That bike

Why be sad about it? The new bike suits the rider better even for jobs
where the roadster is nominally better (why anyone would prefer battery
lights to a dynohub on an urban utility bike and how anyone can find a
Nexus 7 more complex than a DualDrive are both beyond me, but if that's
how Elisa feels then that's how she feels) so get some money and space
back and sell it on.
