Austin TX has a lot of things you seek, but it is a relatively HCOL area. You would probably have to live near Central Austin (downtown or UT campus) for a truly bike-friendly commute, and houses in that area are very expensive. East Austin tends to be less expensive but less bike-friendly in some areas. The heat in the summer might make it brutal for a commute. But everything else is available -- Whole Foods (or Whole Paycheck as we call it), farmers markets, live music, running trail around the lake and hiking trails in the greenbelt, Zilker park, indoor/outdoor rock climbing, paddling on the lake, loads of sunshine, a lot of people your age.
