Hi: Thanks for the reply. I would be modifying the bike myself, so I thought that this might fit. Having seen other delta style trikes, I don't think that this would be too high, as it has a 20" rear wheel, which is common for this style of trike. See the Hase Kettweisel for reference. A tadpole...
I recently acquired a Rans CLWB recumbent with the intention of converting it to a e-trike for a disabled family member. I seem to recall plans or a kit for this.
Here's a link to a picture:
