I rode it twice in two days - the first time I had a full on panic attack which I've never had in my life......it wasn't pretty and I was mortified. A 42 YO man had a full on melt down because the CM and it so tight I had a hard time breathing. I'm not small but not too large, 5'10" 225. I managed to save some space today and wouldn't budge when the CM adjusted the restraint. Love the ride itself, loathe the restraint system. The larger people have my respect for riding this, it's not easy.
