Patrick,
Have you looked into the Cruzbike http://www.cruzbike.com/ ?

They have complete bicycles or a kit that converts a Y-Frame moutainbike into a recumbent. One of the problems I had with both my recumbents ( Vision and Rans Statos) was transporting them and their cost. The Cruzbike option has recumbent advantages with DF dimensions. Would like to hear about your progress.

Regards,

Walt
