Didn't bust out the big camera (thus the lack of background blur), but here she is:As promised I also replaced all the yellow zip ties with black ones. Much less ugly. I’ll see about snapping a photo of the set up tomorrow if I can be arsed to dig out my big camera and some lighting.
The battery pack is annoyingly large, but the controller is tiny (on top of the front part of the rack) and the geared rear hub motor is both tiny and super unobtrusive in person: it's basically silent.
