So I purchased a mongoose dolomite 26 inch bike. I have a zeda 80cc Motor attached to it. Anybody know roughly how fast it will go?. I’m kind of a “Big football player guy” 6 foot 3 290 pounds.

Also the rear hub is 1.18 inches. I was told I needed a special hub adapter so the chain wouldn’t hit the fat tire. Anybody know which one?
 
Welcome to the forum Joshua, I haven't built a big tire bike so I have no first hand knowledge. What a lot of people do is add a jackshaft kit to clear the tire. My son has rode my bikes and he's about your size, even the little 48cc engines pulled ok. Its all about gearing.
 
As for the hub adapter some have modified the one inch with a die grinder or Dremel, a carbide rasp will remove aluminum fast. My 66cc no name eBay engine will do 35 with no problem, it is modified and I'm running a 38 tooth rear sprocket, I weigh 215 lbs.
