The 49cc 4 stroke isn't a bad motor it can carry heavier people decent, 38mph on project farm's video testing but he's not that heavy. Bigger rear sprocket will help 56 tooth or so will carry you right up.
If you sand/mill out just a fraction of a mm on the base of each side it won't creep anymore. Gotta mic your hub then mic the hole the mount makes when held together flush - some bikes have slightly larger or smaller hubs than expected. Split the difference and take that amount off each side so its still a fairly round circle. I just aim for ~.2mm smaller than hub diameter so it grabs it tight but doesn't cause a big gap between pieces or too much pressure on it. Too tight will likely crush the cheap hubs, and too loose will make it push into the spokes like above. Blue loctite on the bolts are a must as well.Schwinn = 14ga,, like most box store bikes...
the 3 arms rest against the spokes, tho these are so much better than rag joints, but spokes do get bent as these creep into the spokes. scuff up your hub and the inner diam of the adapter.
they are the most common setup ppl are using. only way to get better is for disc brake mount with the 6 bolts to the hub. little bit involved tho if you want to keep the rear disc.
I'm looking at mine now, think it has abt 500 miles with this wheel and it has slipped 2mm into the spokes. torque the 2 bolts tight n use blue loctite you'll be ok for a long time
