20 miles is definitely a nice bike ride 2-3 hours maybe less depending on how hard you want to push it. While you can carry more, with a bike you'll be moving fast enough that you don't need to carry more and it makes it easier to change your route to one that might be longer but bypasses areas that should be avoided.

The bicycle sounds good.

I would choose a medium-to-heavy frame (and wheeled) bike,
because it can easily take the punishment, curbs, holes, etc.
This allows many more emergency avoidance options.

Nobbie tires are Not good; they increase the work
considerably.

CTENGR,
Undoubtedly you have noticed some private security cops
(carrying real guns), riding this kind of bike and they
can really cover ground quickly.

Interesting. When I bought my bike steel was still the primary material, but the Cro-Moly steel was getting thin walled and a bit lighter. I ended up with a mountain bike design but with high-end dérailleur, brakes and wheels, and 2" slick tires rather than knobby tires. It's a great bike for urban bike paths, cobblestone streets, curbs and pot-holes. It's not as good on dirt, a knobby tire would be better there, but it's much better on any type of pavement.

I don't think there's any need to apologize! It's nice to forget about things you've put in a kit and when you go hunting for somethig in there, to find it again, after it's been out of sight and out of mind for so long. It's kind of like a little Christmas all in itself...

Well that's a very optomistic way of looking at it. I was thinking more along the lines of what would happen if I forget something's in there when I need it. Nothings worse then needing something and forgetting that you have it.

I agree with DrmstrSpoodle. This does bring to mind, though, a “contents list” as a suggestion for something to add.

A "contents list" is even more important if you think you'll be bugging out with someone else (who might not know about everything in the BOB). I find it's also handy to note the general location of an item (side pocket, front pocket, main compartment, etc.) on that list.

I will definitely be adding as contents list. That's something I didn't even think of. Thanks.

I would switch out the 2 $20 bills for 1's , 5's and 10's. That way you don't have to worry about change for anyone. Therefore letting you get in and out of places quicker. To be honest, I would have more then $40 considering if SHTF then prices for everything are going to skyrocket.

The 550 cord is definitely a keeper, and the dacron line would be a nice compliment to it; strong enough in its own right to be functionally desirable, not so bulky so you can keep 50 yards in a pocket for edc. I have 550 in my BOB, and the dacron in my edc (and more now in my BOB as well, all 120 lb test, about the diameter of dental floss).
