Hi folks. First post here. I am glad to find an active biking forum. Please move this thread if it is in the wrong place.

I am a student and community 2.5 miles each way to school and back nearly every day. My backpack is really heavy so I am looking into cargo options for my Torker U-District bike. I really don't know where to start. All I know is something that I can strap the bag to would be amazing. Do you all have any suggestions or options? Thanks, folks!!!!
