So I just went back to the beginning and read through most of this thread again. Once again nice work on everything!

I was wondering which battery you were going with, and knew it was probably in there somewhere. 20ah pack dang! That will give you some nice range for sure!

I was wondering if you could elaborate on the little bracket you made to keep the BBS from digging into your BB shell. I've been wondering what exactly keeps the motor from falling/rotating downwards under its own weight. My frame isn't as nice as yours but it's still in good shape and I'd rather not gouge it all to pieces. Someone had the idea of putting a stainless screw clamp around the down tube, and then a large screw clamp around the BBS motor body (perpendicular to the first clamp), and using the two in combination to hold the motor up against the down tube. I was thinking of trying that along with some sort of simple ring spacer to keep the BBS unit from digging into my BB shell.
