Well there's so many different sections to this forum, I'm not quite sure where to post this. I'm a newbie looking for a commuter bicycle so I thought this forum would be my best choice. School is about 3.5mi away on a hilly road or 5mi on flat road. Looking to get a bicycle to ride to school and back to save on gas. The problem is I have no idea what to get.

I understand bikes can be extremely expensive but I'm fairly sure I won't be a very serious rider. So a cheap one would be most desired. I'm about 6'1" ~170lb. Anything else you need to know about me to make a suggestion?

Thanks a lot guys! If this is in the wrong section, can an admin move it?
