It looks like the BMC 750-1000W motor and maybe a Currie gear reduction system using planetary gears. Please provide info on how the mid-drive is made. Do you have a jackshaft? Is it custom made by you or is it commercially available. I have a friend who wants to power up his 3-wheel trike and I believe your system will work well for him.
nice bike!! what kind of watt hours per mile do you get? what battery are you using and is the BMC motor modified running an external controller? your legs looked to be spinning pretty fast, maybe you could run higher gearing?
OOHHHH, Subway the sandwich place.

I get 6 - 12 wh per km. The motor uses a controller. I ride in a lower gear to reduce strain. I hound that "spinning" is best with a recumbent.
