sometime in the near future i intend to go on a tour of my home state, iowa. my current bike is dead and i'm in the market for a new one. being more strapped for cash than most seem to be, i.e. $600 is out of my price range, i decided i'm going to get a waly world (wal-mart) bike. specificly this one: http://www.walmart.com/catalog/produ...uct_id=8399245 . would this be a good bike for a beginner such as i, for one planned as such?
