That's a large amount of stuff to be carrying around.

I think you are bringing way too many knives. Try to keep it simple. Shelter, water, warmth, some food.

Your clothing seems adequate.

I would bring more dehydrated foods, and more water instead or all these knives.

Wow, lot of duplication. If you were in a support vehicle (van, pick up, etc) for a bunch of guys on bikes, it would be ok, but on a bike you don't have a lot of space. The image I'm getting in my head is that this a pretty decent pile of gear.

Pick one (1) saw, one (1) fixed blade- there is nothing that one of them does that the other doesn't do just as well, is there? Dump the cheap folder, they generally aren't worth it. Ditto the tube tent, you've got garbage bags and a tarp.

Better line than just paracord. Don't get me wrong, it is good stuff, but it really isn't all that strong- some 1" nylon webbing would be a good addition.

FAK- what is in it?

FWIW, Jeff, it seems to me that your worst-case scenario would be a bad spill with injuries. Broken arm or hand, dislocated shoulder, badly scraped up leg. Maybe a mild concussion, even while wearing a good helmet.

Since you'd be on your own for at least 8 hours, possibly with very limited mobility, that would become a genuine survival situation.

Correct me if I'm wrong, but I get the impression that your gear list assumes you will be generally able-bodied.

Perhaps you should consider what you'd need if the worst happened? If you were hurt, groggy, could only crawl, what would you need?

(Hope this never happens, but it doesn't hurt to think it through.)

How about substituting some Gerber milk bags for some of those those Ziplocs? Very durable (and sterile) container for water storage.

Also, a SAM splint would be just the thing if you were injured in an accident and had to move. Maybe some WaterJel/BurnJel or 2nd Skin Burn Pads for abrasions/road rash if you dumped your bike. Just thinking a basic FAK and Motrin may leave something to be desired in a road accident (serious or not). For the activity and circumstances you have described it is not just about the wilderness survival, but surviving a potential accident (or breakdown). Your kit really needs multiple components: 1) breakdown, 2) accident/first aid, and 3) surviving afterward in the Michigan forest 600 to 1000 foot elevation. I think you have no. 3 covered. If you are not mechanically inclined maybe no. 1 is not a priority. You already have a multi tool and duct tape, and a few zip ties to secure a hose and a wrench could come in handy even if you cannot rebuild an engine. I just don't see a lot of preparation for no. 2.

You mention that weight is not a consideration and everything is in a backpack, but I have to believe that the farther you may have to hike or move the more of an issue it may become (and even more so if you are injured in an accident). Accordingly, I would agree with some of the calls to limit the redundancy (Although I understand exactly where you are coming from). Maybe a smaller pack within the pack? (There I go, talking about limiting the redundancy and then encouraging redundancy as a solution)
