bike or a road bike? The funniest answer I saw was that a 270 pound man should buy a treadmill first and loose some weight before cycling. Nevertheless, when thinking about the poor quality of Walmart/Kmart/Target bikes, it just makes good sense. Cheap bikes from these stores just are not made to hold the weight. The frames are not that good and the plastic pedals are a joke. I have a newer mountain bike that I have had to replace the pedals on already. My twenty-something year old Motobecane bike is built much better and has metal pedals. I don't have to worry about breaking anything on that old bike, but I have to be very careful how I ride the new bike or it will break. Is it just me or is everything made cheaper these days?
