How I Mount My Peak Design Everyday Backpack on My Bike

Two years ago, I started biking to work more often. I knew I wanted to mount the backpack on the bike. Initially, I considered getting a bike bag. But I did not want to give up my Peak Design Everyday Backpack. Then I considered a pannier kit which converts any backpack into a bicycle pannier. But I thought it might make the backpack look and feel clunky. Since I would still use the backpack a lot without a bike, it was important for me that I’ll still enjoy wearing it.

So I figured out a way to mount my Peak Design Everyday Backpack on the side of my bike, with no additional equipment, just using the straps of the backpack.

I attached the backpack to the rear rack using the external carry straps.
To make sure the shoulder straps don't get tangled in the wheel, I fold them over and use the sternum strap to keep them in place.
I attach the backpack as far to the back of the bike as possible to give my heal enough space when pedaling.
When hooked in to the attachment points, the external carry straps keep the backpack securely attached.

It’s more tedious to mount and dismount than a pannier bag, and not as fool-proof. Once, one of the external carry straps came loose, likely because I hadn’t properly attached it in the first place. Because of the second strap, the backpack was still attached though.

I’m still looking for an easier way to mount my backpack on my bike, without getting a different backpack or adding gear to my backpack. This hanger looks like it might solve my problem.
