Weight Limit?

I am looking at getting my first Oneweel! I have ridden an older Pint and loved it?

My biggest question is about the weight limit. I weigh about 276 lbs. The limit listed on the Pint S is 250 and the XR Classic is 275. How critical is this and what does it affect? I am sure that uphill and off-pavement riding would be where most of the impact would be. Are there any safety concerns? Does it void the warranty?
