Re: Building tadpole trike for street use

I will only be using the front end assembly of the Polaris quad, not the frame. I have already given the CG thing plenty of thought and will be sitting just aft of the front end, down low, not up high like the donor quad. With 3ft of body width in front and A-arm assemblies sticking out from there I will probably end up with a tire-to-tire outside width of at least 60". Thanks for the concern though.

Raising your seating will raise your center of gravity and the rear seat will move the CG back toward the single wheel, although the front mounted engine should help. A narrow trike with a high center of gravity is a recipe for disaster. Thats why most trikes are wide and low. Just make sure you get the design right before you build it. There is some good info out there to guide you if you do some searching. Robert Q. Riley has some good info on this as do some others. Good luck and have fun.
