We rode about 6 times over the weekend and even though its tight, if you don't push the lap bar down too far you will be fine. My son is 6'2, I'm a size 20 and my husband is tall and wide. It's a tight fit, but if your careful with the lap bar it's not that uncomfortable.
The first couple times we rode I made the mistake of pushing the bar down so it was snug against me and ended up with my legs painfully pinned together. When I stopped pushing the bar down all the way it was much more comfortable.
Also, make sure you set your bags on the ground before you sit down so you aren't stuck holding them the whole time.
