I didn't ride my folder as the wife and I were on a rented tandem. I had told her about Bike Friday tandems as we were riding along in the 5BBT and how I dream of us getting it... AND WE SAW ONE ON THE ROAD. How cool is that? It was a mother captain with child stoker. They seemed happy with it. Anyhow I didn't see as many folders as I thought I'd see but I think that's because of the dilution factor of the 5BBT (many more casual riders who haven't been on the bike much).
