I havnt tried actually driving a bike with my school laptop bag, but it holds my laptop(securely), 5 subject notebook, 2 folders, your average textbook, and a charger all in one compartment. Then you have a second "folder organizer" that can seperate like 3 stacks of paper...I dont know how to describe it, and then it has a compartment for pencils, pens, ID cards, tape, sissors. Plus multiple other little pockets, including 2 side pouches and a top "dome" that you cna put like your lunch in. If you want I can try to put some pics up.
It has like 1700 cu inches or somthing, 600d polyester, adjustable shoulder straps and I was absolutely in love with it through my freshman year of highschool, but it did weigh a lot for a backpack.
