Officially, yes, but my wife and I rode home together 2.5 miles on mine friday night and my frame doesn't have any visible cracks. Yes, that's right, the two of us were on a single Carryme: me in a normal riding position and her standing on the rear rack trying to put as much weight onto my shoulders as possible (240 pounds total).

It was a bit chilly and when the diner surprised us by cutting back their hours to 3AM we didn't want to wait for the next bus. So it was a good thing I had my bike with me.

The official weight limit can, naturally, be found in the owner's manual and although you can probably take it with a grain of salt I think the Strida, with it's 100kg weight limit, might be a better choice for larger individuals like yourself.
