After a trip to Europe with my son Max that included cycling in Germany, France and Italy, I decided to sell my aluminum/carbon K2 road bike and build a take-apart travel bike for touring, and have that as my main bike. I thought about buying a Bike Friday or an Airnimal, but I remembered reading an obscure post somewhere about someone who built a take-apart bike that was very small when disassembled. I scoured the internet and found recent info that led me to Drew Devereaux's Portable Bike. I emailed him and he said it was ok with him if I copied his design for a one-off version. He's built about a dozen bikes like this, so I thought, "why make mistakes with my own design?". I ended up making mistakes with his design, but fixed them for the most part, and did a few things differently. Anyway, see pics below for what I came up with. The first time I rode this bike it felt strangely familiar, and I love it. It's set up now with an upright position, but the bars could be lowered a lot. I like it the way it is now, very comfy with a nice view of things as you ride. Perfect for touring. I still need to make front and rear racks, and will do that soon.
