No worries fella, how come you haven't used it though as mine has been a godsend in terms of mobility since I snapped my Femur into 3.
I'd looked at the 'off the shelf' options but managed to assemble mine for just short of a grand (by fitting an electric 'kit' to a trike) and ended up with a better (for me) solution.
I left out the 'assist controller' and crank sensor (although the cabling is part of the wiring loom) which saved me £50 on the build but mainly cos I wanted to be able to not use the 'assist' (and reduce the battery range) when I was just pootling around on level ground so not needing the extra 'oomph' it provides.
Mine is in my Avatar but here's a bigger pic of it.

EDIT - BTW I still have the mudguards, basket and original seat but I chose to build it up like this for my own taste.
