I have a Bike Friday New World Tourist and a Waterford Adventurecycle (S&S couplers). The Bike Friday lives in the UK while the Waterford is in the US. The one I tour with depends on the continent I'm on.

I find that the Bike Friday rides like a "normal" bike, though it is a bit twitchy. My main complaint about it is that when I am standing over it, say, to take a photo, the bike is unstable. On my last tour (September, 2022 in Ireland), the bike went down (this is fairly common) and it pushed me down, as well while I was trying to take a photo. That never happens with the Waterford.

Also, for the first time, I bought a bag specifically designed to hold the Bike Friday with the thought that I could use it to take the bike folded on a train or bus. While folding the bike doesn't take long, getting it into the bag was a major hassle. Carrying the bag with the bike in it was very difficult and I could only do it for a few hundred feet at a time before stopping and taking it off my shoulder for a short break (the strap provided isn't padded and it "cuts" hard into the skin). Eventually, I realized that in order to get the folded bike into the bag, I had to do a bit of disassembly, like remove the rear rack and take off the front wheel. Still, it was a struggle. The idea that I would ride up to a train station, fold the bike and put it into its bag and then get on the train was a non-starter for me.

In addition, once the bike is in the bag, it is both unwieldy and bigger than any of the luggage storage places on the trains I took. I ended up storing in the place on the train where one would put an unfolded bike, so nothing was actually saved there. When folded the bike Friday is an assemblage of cables and metal bits that is hard to carry easily.

I write all this to let you know that if you are looking for bikes that are "easy" to fold and take onto trains or buses, be sure that you actually see what it takes to fold the bike, what it looks like when it is folded, how easy is it to carry when folded, and how hard it is to get it into a bag, if needed.
