It's defo fun, that's for sure lol - I'm using a bit of everything most of the time, I'm still learning how to ride the thing so I've yet to refine a method... but generally it's pedal & electric for gentle maneuvering like the paths, turn arounds, lots & just rollin' down the road with pedaling & both the electric motor & four stroke engine for hard take offs like intersections or hill assistance to maintain speed, ICE alone for upper cruise.
It's gonna be a little while before I can get ya some numbers, I'm still breaking in the four stroke & dialing in the alignment - both factor heavily in fuel efficiency, while I haven't bothered figuring mileage yet I have noticed a significant drop in consumption already, the first runs she was
hungry lol & now she's become quite a bit more demure in her appetite anyway
