backpedal?
PowUnity fits in either the Bullitts fine, older gen e6000 size frame extremely easily, E8000 easily and E6100/EP8 generation frames (has the Gates belt drive cut out) fairly easily. Cable management is not really tight in those, but a bit fiddly, you need a bit of tape or an extra pair of hands to make sure all cables go in the right place and don't get trapped.
Had a Brose motor powered 'Trio' bike the other day, the shell for that is very tight, a PowUnity would have fitted (the cylinder shaped unit) but customer brought a brand i've not heard of before that was a rectangular chip with a lipo cell strapped to the top of it (size of an Iphone 4), wouldn't fit anywhere 'inside' anything. So ended up making a space for it inside its cargo box that had most degree's of visibility to the sky and powered from front light circuit. Seemed to work, though supplied connectors were utter garbage.
