Speed and these don't really mix:
Those need power to keep the spinning in the muck to keep the treads open and grabbing. Not the exact thing you get from gearing but simple displacement. The atv engine buggy which is next on the project list is the trail/joy riding machine. The one I follow my son around in his gy6 powered one.
But what do I know my daily driver is a s10 with a v8. I like little vehicles with big engines.
