This is a Infinity with underseat stearing and using a Golden Eagle bicycle engine. I put this together a few years ago and what a ride it turned out to be.
Because I was sitting so close to the street and very little obstruction ahead, it gave me the feeling of flying low. I can tell you, it took some getting used to but a very comfortable ride that was best for open road distant riding.
The drawback for me was around town. As much as I tried I just could not feel safe trying to maneuver in tight traffic, but other than that it is a neat setup.
