I just received me new $1000 fatbike called the gravity bullseye monster pro with bluto front suspension . Heres the link to my bike
http://www.bikesdirect.com/products/gravity/fat-bikes/fatbikes-monster-pro-bluto.htm
I took measurements and the chainstays come in far enough to allow the B.B. to be cutdown to 70 m.m.
Now I just have to decide if im ready to butcher a brand new $1000 bike with my grinder and plasma cutter to allow a BBS02 to fit it.
Well this is a revelation . The above fat bike I just purchased, will allow a common brushless hub motor , purchased off ebay for $193, to work on the rear dropouts . I may lose some use of all the gears , but thats not important to me . This means I wont have to modify the front " hole thru" dropouts nor use a BBS02 mid drive system .

I may lose some use of a few of the gears , but thats not important to me . With the fatbike tire fully inflated , there is just enough room on each side of the rear frame so the tires dont rub.....if neccessary, im sure I could put a extar washer on each side of the inside of the dropouts, to get a few m.m.s more clearance if needed.
This means I wont have to modify the front " hole thru" dropouts nor use a BBS02 mid drive system .
Gridlock, heres something I also considered , if someone wanted to mount the hub motor on the front of the bluto rockshox.
Instead of cutting the aluminum dropouts on the shocks , a person who has a welder could do this :
" use a spare bike / spare front fork which is made from steel and isnt a " hole thru " design . { I have a giant brand bike for this purpose} . Cutoff about 4" -8" of the fork, with the steel dropout attached. Then measure the inside dimension of the dropout hole on the bluto rockshox. Then get a all steel bolt about 2" long that will fit snugly thru the rockshox thru hole dropout. Weld that bolt to the outside of the steel fork , about 1" inch above the steel dropout . Now you can slip that bolt thru the hole of the rockshox dropout , tighten it down with a locknut , and use at least 2 heavy duty steel clamps to fasten the upper portion of the steel dropout, to the rockshox fork tube.
This is just my own idea I came up with, and I am not suggesting anyone else try this....but I may try it eventually.
