Well, I've got to report that the folding bike issue is settled as far as Europe is concerned. My daughter has made it very plain that she doesn't want to tour on folding bikes. Let's face it, they do look like they ought to come with clown suits. I now have two of these folding bikes, one of which is still in the box. I think I'll just keep both, and at some point we'll use them. But as far as Europe is concerned, we'll buy or rent in Europe. There are some decent 150 euro bikes in Heidelberg; I just hope I can get a bike train ticket to go with the ones I already have.
