Hello cat in the hat, from the description you've given, it sounds as if you still want a BMX bike! But I think a BMX bike would be fairly uncomfortable for 9 mile rides eventually. Have you tried looking at the local Craigslist?
I noticed someone has a Bridgestone MB-5 for sale in the MSP CL for $120--nice bike, looks to be in good shape blah blah blah...you don't need to go to Target to get a cheap bike! If you wanted a cheap road bike, someone's got a nice Schwinn LeTour for $50! That would make a great road bike (disclosure: I love vintage bikes). Since you're wanting to do conditioning for football, weight wouldn't be a big deal for you.
Welcome to BF!
