Here’s a shot of the Margo just before a car-trip to Portland.  

Front, rear, seat post, pushrod, and steer shaft.  If my car’s ceiling was a few inches taller I could leave the steer shaft and pushrod assembled.  If that were the case, the bike would take about ten minutes to assemble.  As pictured above, it takes roughly 15-20.

As you can see, much of the bike is left assembled.  The fork, handlebars, stem, and brake housing are all left alone.  The handlebars and stem stay with the front half.  The derailer cable and housing are detached from the derailer and pulled though to also go with the front.  The rear brake cable is disconnected from the lever and stays with the rear.  

While this bike isn’t intended to be a travel bike, the bi-parting frame makes it possible to bring it along when I travel.
