Thanks Toshi, With the water bottle mounts and a bit of bracing against the top tube, a solid mount is quite straight forward for a tough steel frame like mine.
The battery box with is surprisingly not an issue at all for pedaling and I've yet to knock my legs against it even though I do plenty of pedaling.
I'll get some close up photos of a few little details like how I turn the controller on and off externally, and how the side panel slides off soon.
I don't think the Bafang will stand the test of time so I'm already thinking of my future options. So far I haven't been able to bring myself to bolt that big 9continents motor to the front, the bike is already a handful to carry up quite a few steps in and out of my apartment. I carry it partially by the box and it hasn't bent or shifted out of alignment at all. If it did, I'd know because the crank clearance is so close!
