Would like to try a rear engine mount.

Hey all, about 12 years ago I built an 80cc 2 stroke on some dumpy walmart bike. It was great. Now I'm back at it and wish to try a 4 stroke kit this time. In IL if I keep it under 20mph, I can be 100% legal on the road (got a DUI many years ago). This time around I want to try a rear mounted engine.

It just seems safer, not being in between my legs and all that. Also the 4 stroke kits often require replacement cranks and I'd rather not mess with all that.

Any suggestions on how to accomplish this? I've looked online and I can't seem to find any mounting kits other than this: https://www.ebay.com/i/323335342428?chn=ps.

This is the bike I just ordered: https://www.amazon.com/gp/product/B07LCGLW9G/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1. I got the 29" frame single speed.

I'm also considering putting a different sprocket with more teeth on it to slow it down. I weigh 250lbs so I need to see how it handles with the stock build first.

Any help or advice i appreciated!

I truly enjoy my rear engine mount. Which runs through a Staton Inc 18.75 gearbox and uses a Staton Inc double freewheel shift kit.
