Re: i weigh 277
You just need to find a bike first that is rated to carry more than your weight. For an example the genisis Onyx from walmart is rated to carry 350lbs of weight. Now that bike with a good 66cc and a 44 tooth sprocket and a good nt carb with a good ngk spark plug and 91 octane gas should carry you like you weigh 190 lbs. I weigh 210 and those bikes fly uphill with me. They don`t slow down at all on a pretty steep hill if I already have my speed built up. So there are bikes out there that will carry you with no problem! You just won`t be flying around like some of the smaller guys.
