I love it....good work...
I'm hoping BF comes out with an Xtracycle kit for their travel bikes...so I can get my cargo biking fix and still be able to take the whole rig apart and store/transport it easier than a Surly Big Dummy....
Recently, I had an e-discussion with Walter at BF regarding modifying a QTandem to include a middle section which would be compatible with Xtracycle components. He seemed somewhat optimistic that the service department would be willing to take it on as a winter project.
