Hi folks......New guy here.....Don't have a bike with a motor on it yet...I have a bunch of Questions for you....I don't even know if they make a bike or motor that will carry me.....I'm 66 years old ( don't want a speed demon ) Here's the problem...I weigh 260 lbs....If I can fit on one I was thinking of a 50ish tooth rear sprocket.....Plus a 66cc motor....You guys are the experts, so I'm open to suggestions
