Hey Christ,

I think you are underestimating both the performance and fuel economy capabilities of a 125cc trike. I don't remember reading if you plan on a fully enclosed aerodynamic vehicle(ala Aptera) but if you do, then I would expect at least a hundred mph max speed depending on gearing and, during normal(50-70mph) driving above 100mpg fuel economy. The Apteras early fuel efficiency rating was better than 200mpg. Don't know that they ever achieved that number. I've seen a 50 pound fully faired bicycle go over 80mph before. That's on less than 1 horse power of output. Good luck on this project it should be a fun one.
