Shootingstar, I bet it was a Dahon. They make quite a few folding bike models. I will only be in France--in Brittany and in/around Paris. I don't like to cram too much in a vacation, and I only have a few weeks.

Here's what I was able to pack in that suitcase. It weighs 55 lbs; 70 lbs is the limit for international flights:

bike
pannier rack (a special folding one)
bike tools
folding tire
underseat bag (tube and power bars)
protective plastic and felt covers for various bike parts
cycling shoes
2 pr. cycling shorts
rain jacket
2 short sleeve and one long sleeve jerseys
1 pr cycling tights
arm warmers
2 prs pants and 2 skirts
6 blouses and one cardigan sweater
3 scarves (it's France, afterall)
6 pr undies and 4 pr socks
toiletries
one old towel for when I put the bike together
soft nylon bike bag (for when I take the bike on the Metro)

I roll my clothes up in Eagle Creek packing cubes, so they are protected from the bike grease. I had to sniggle and snuggle the clothes around the bike. Going with a few smaller cubes is more flexible than one large one.
