Do you see what I meant by the disc rotor location relative to the axle step in the photo? When you add the thickness of the rotor and the rotor bolt heads you will have to use spacer washers to keep those rotor bolt heads from digging into your dropouts.
Yeah, looking at Andreym's pics, I do. The Norco A-line I am using is 150mm, so I plan on putting spacers on both sides anyhow. The A-Line has removable dropouts, I am hoping to handle spacing issues with the replacements I'm having machined.
I'll probably throw a disk brake on there, but on other bikes I have just used regen for the rear brake.
I LOVE that thick axle - plenty of flats for a torque arm, the phase wires are brought out the right way, but I am suprised that the italian guy was able to get 250a through them.
Here are a few of Andreym's pics as a reference:
