you can pick up some panniers for 30 bucks for low end models...my friend bought a dawes,its a good bike but when he got it, he pretty much needed a whole tune up, especially his wheels they were so out of true,but could have just been a fluke..just make sure your bikes set up 100% properly,as most bikesdirect bikes dont come rideable outta the box..once he got his bike tuned up it rode exellent...600 miles is a pretty decent ride so just prepare for the worse and youll be fine..bring an extra tube and a mini pump just incase..and learn how to change a bike tire if you dont...also make sure you buy the right size dawes.
