Hello. I'm a college student and I'm looking for a good bicycle to commute with for the next two years. Everything that I need is within a 5 mile radius - as in the college, work, etc. My build is skinny-average, 5'6". I want a bike that I primarily use to commute and (maybe) on occasion go on biking trips for a few days. For example, a bike trip from Miami to Key West type of deal (~160 miles). What do you ride? What do you prefer? My budget is anything up to about $600. I'm super excited to get a bike! Thank you for the input
