Well On the lighter side. I took it for a run just now. I know ( Bad John Bad ) Still impressed . I had a chase car follow me . I went up one of the steepest hills near bye. It's about a 1/2 mile climb 30% grade to the top. Was impressed , didn't seem to be loosing any power at all, I was doing a registered 50MPH . Chase car said about 46 MPH. still not bad . Speed limit on the hill is 35 Miles and hour. It would make a nice around town / back road trike someday.
