Bests & Worsts Reviews from Amazon

So, I'm not in shape so that's why I got this thing. I don't outweigh its maximum weight which is 300 lbs. I weigh about 275 lbs. I've been riding on this thing a few times, I'd say somewhere between a half dozen to a dozen times and today the seat broke. Not the metal bits of the study part of the bike but the seat itself. I wasn't leaning I wasn't doing anything. I just heard a crack and so forth. I would love for the manufacturer to replace JUST that bit, but it doesn't appear there is any way to write anything but a negative review. I am pretty sure they need to write new stats.
