Having been a rider and almost getting a rider instructor certificate... I was thinking shafty or belt for ease of maintenance only... Power/efficiency losses through a shft drive are higher than a chain or belt drive though. And my original ideas for the three wheeler were more performance oriented, but wouldn't take much to be FE... And I would prefer a 2 seater, side by side. And a chain drive setup could be adapted to allow an electric reverse. Tire choices for the rear could be made a little taller to adjust final drive also, if gearing for what you want wasn't available, or using a shafty.

As for riding, I never really liked the weight transfer when on the throttle with a shafty. Could cause probelms in corners if getting on or off throttle. But shouldn't be a problem for a three wheeler. And using 2 wheels out front would be more stable than VW powered trikes.
