I bike 7 miles round trip every day and this backpack has made it much more enjoyable. Before I had a smaller, simpler backpack that lacked structure and was not waterproof. I had to take it off of my back if I needed anything. I have an Osprey pack for backpacking and love it, so I decided to splurge on a better quality backpack for daily use as well.
I also used to drop my keys at least once a week, but with the handy retractable cord and side pocket on this bag, it's impossible to drop them and I don't have to take my bag off to access them.
The rain cover is great and saves the bag from city road grime when it rains. You have to set it up in a certain way to prevent the cinch from poking your back, but now that I figured it out it's all good.
I love the giant side pockets! On one side I keep my water bottle, and on the other my phone, key card, and gloves when I'm not wearing them. Basically anything that I might need quickly but can't keep in my pockets.
