Greg, you'll find the PhotoBackPacker to be perhaps the best system and lighter than most of the others... especially the LowePros. I replaced my LowePros with it in order to reduce weight. It is very comfortable to wear.
Now, as for biking with all that gear mentioned earlier... I might suggest replacing the bicycle with a Honda Goldwing and sidecar or trailer... or perhaps a mule..... ;-)
With this setup, you get a back board that you attach to the bottom of the backpack, then you use the velcro strips to assemble whatever boxes you want for your camera, lenses, and accessories. You don't specify your camera, so I'll assume medium-sized field, for which the "894" box will work. You may need smaller or lighter, it's easy to configure on the site. You'll probably velcro that at the bottom of the back board, and if you shove it all the way to one side or the other, you'll have space for 4-6 holders next to it.
Then, assuming you use a 4x4" or thereabouts lens board, you'll get two of the LS-1150-4 lens cases. I have two of them, one fits an 80SSXL, 120 APO-Symmar, 200 Nikkor-M and a 300 Fuji-C, with another spacer to give about a 1" wide area where I store a spare lens wrench, lens cloth, and puffer brush.
In the 2nd "4 lens" box, if I'm carrying my full lens load, I'll fit the 250/6.3 Fuji and 165/3.5 Zeiss, plus a larger area that carries my light meter, loupe, and a few other tools. If I want to travel lighter, I just leave one or both of these heavy lenses at home. Two of those should carry all 7 of the lenses you list, plus space for a few more things.
Above the two lens boxes is space for the dark cloth.
On the inside of the main flap, I have space for a 2nd focusing screen back (with wide angle fresnel), and one of those wallets that holds a bunch of filters. You can instead fit a bunch of film holders in either of those pockets instead.
The outer pocket carries less used accessories (pen, grey card, IR filters, laser pointer for focusing). The outermost outer pocket carries a couple bungee cords.
I also got the deal where you get two side pockets (RKSideP) for the price of one when ordered with the backpack. I could, in theory, fit about 6 film holders in the pack on either side of the camera box, and 16 holders between the two outside pockets. In general, I'll carry 6 holders in one outside pocket of regular film and 3 of IR film inside the backpack to keep them separate. If I want to shoot more, I'll probably bring the 2nd external pocket, but leave it in the trunk of the car.

The btzs focus cloth weighs almost nothing, and make sure you use a Gitzo carbon fiber tripod (or something similar). Leave the camera on the tripod and throw it over your shoulder...
I don't know how long you are out, but be realistic about how many shots you take in a day. I can take about 20. 8 holders is probably fine. Stop bracketing (if you are) and get your development down...
Just my 2 cents...

That's great advice Lenny.
For two years, I lugged a Deardorff 8x10 around with meter, a Nikkor 450 M and 3 old holders (which I still own) - sometimes I even remembered a cable release. I made some of my best images during that time and frankly never felt short changed while out shooting. Some of the best shots I made were as a result of having to work a composition in because of the tools I had available - I was forced to be creative instead of just going through the motions of shooting. I own a bunch of photo gear and have to confess that most of my worthwhile photography happens when I'm focused on the subject and not on the gear in my bag. It's one of the reasons I shoot a 50mm lens on a 35mm rangefinder week in and week out... it keeps my LF gear completely manageable in a shoulder bag instead of in that revolting Super Trekker...
Photobackpacker packs are the best. Use a Burley type trailer on a bike or an InStep jogging stroller on flat land.
