The BauBike by Michael Ubbesen Jakobsen beautifully squares up everything. The frame also leaves an open end piece above the back wheel to add accessories like an extra seat or cargo rack. It all works very nicely, especially the contrast of the raw steel frame with the classic Brooks saddle (which I’m privileged to own thanks to my good friend Kent). Now I really need the BauBike to go with it.
Thanks to Mary for the link.

This has the makings of a great utility bike for trail work. That open piece behind the seat is begging for a chainsaw scabbard. http://www.baileysonline.com/itemdetail.asp?item=50121
kcthree – That would be a great accessory, and not just on the trails. Ever ridden down Folsom street at rush hour?
