i don't have a Bird frame but i do have what is left of a El Tigre frame but always been a fan of the Bird Lark so this is my conversion. purchased a white banana seat and sissy bar that fit good - i guess the seat could have been a bit longer. planning on using a bronze color lauson motor i have for power and plain white wheels. other than the seat and sissy bars i'm using stuff from my stash so maybe $50. or less build.
