The frames are hi ten made in Germany but the welds look pretty janky. I toyed with the idea of sending back the BD and building the Mundo from the frame but it seems too late now.
I'm concerned about both cost and hauling differential. By the looks of things, the Mundo wins in both areas. BD can run disk brakes and is compatible with overpriced xtracycle accessories. It's a smidge lighter as well but I was never concerned with weight. Oh well, BD it is.
