I would like to get a Surly Big Dummy in a year or two. I have a 2008 Raleigh Mojave Mountain bike that I was thinking about using as a cargo bike till then. I don't want to make the $300 Xtracycle investment in this bike. I think buying the Big dummy will be a better decision. I want to know what you all think I can do to this bike to use it as a cargoish bike. I built a front rack and I need to get a rear rack. I'm thinking about getting a rigid front fork to put the front rack on. Any cheap front for recommendations? Thanks for the help?
