Review on 🚴 Lixada Cycling Backpack: 18L Waterproof Bicycle Backpack with Rain Cover for Outdoor Travel, Hiking, and Climbing" by Christopher Wiggins

With a motorcycle. The waterproof lid sucks a bit, but it helps hold water in a bit. I added a bit of parachute to the clamps so I can carry a motorcycle helmet in the trunk and it works, but it's clearly intended for a bike helmet. EDIT 8 MONTHS AFTER: So I grabbed this thing and stuffed it in my saddlebag and then wheeled it back and forth from the office on my bike. The anti-moisture coating inside didn't last long, started peeling off, but the backpack is still intact and functional. Just this week the zipper on the large bag broke so the bag is now in the trash. Overall it was a pretty good 8 month run for the price but it's cheap quality because it doesn't last long.
