That was my original plan when I decided to just for it, I was going to strap my backpack to the rack with bungee cords! However the morning of the inaugural ride, my 15 seconds attempt to strap it down didn't go well, straps from the back pack where dangling everywhere possibly getting entangled in the spokes, and I was afraid the backpack wouldn't stay steady, hence slipping and possibly falling, so I just put it on my shoulders. Thanks for sharing the video, I will re-watch this weekend to see if I can duplicate what you've done and see if I feel comfortable riding with it strapped down like yours (nothing falling)....
