Hey guys, I've been battling depression for 10 plus years now and am constantly tired every day.Recently, I've decided to try biking and,to my surprise, it has made me feel happy,energetic and clear headed in god knows how long.

Now I'm looking to get a real bike as the current bike I'm using is a cheapo second hand bike.My budget is 1000 and am hoping to get the best bang for my buck at bikes direct.I'm totally clueless as to what to look for in a bike,so I came here hoping to get some help with picking.I'm 5'6 btw.

Edit-Alternatively if you guys know any other good bike buying sites,I wouldn't mind either.
