I recommend buying a brompton bicycle.

The rack being super low means the distance between the rear rack and the saddle is almost the exact height of a good backpack. IMHO, it’s the best way to carry a backpack on a bicycle
Edit: Brompton’s small front O-bag is actually made by Ortlieb. I wouldn’t recommend their bags as backpack replacements. They work great on bicycles, but not so much on your back (where the weight should actually be on your hips)


What’s the griddle made-of? Does it have aluminum in it?
