I'm still shopping and I'm quite confused. The trikes I have on my list so far are, in order:

- HPVelotecnik's Scorpion FX (folder)
- Greenspeed GT3 (folder)
- Catrike expedition

I may be interested in Terrtrike and Actionbent (TW) as well but I don't know a lot about those products.
My needs for a trike are:

1 - Commuting to work (10km one-way)
2 - Day long rides on local bike trails
3 - Weekend camping expeditions. I haven't done that yet, but I would be interested in trying a weekend trike-camping trip.

So why the folders? Well, for storage and transport. My favorite vacation spot is about 1000km away and I'd like to bring the trike over. Seems to me a folding trike would be easier to carry in my luxury sedan with non-folding rear seats.
