I have heard that there is a trike kit where the traing or rear side wheels raise and lower when stopping and raise above 6 miles ahour. Does anyone know the name of the company that offers this setup?

You are probably referring to Leg Up LandinGear but that isn't a trike. It's still a bike but with helper wheels when you get going very slow or stopping.
