Yeah.I just realize last night (while reading the manual) that the max weight for the bike is only 310 lbs. I weight right at 200 so no fat chicks... seriously.
My future brother in law was sitting on mine, and my sister wanted to hop on the back to see how it felt. She's not a petite little thing I'll just say and I was like " Sorry, but with his big butt on there you'd need to weight about a 100 pounds for me to let you hop on."
Any future girlfriends have to weigh no more than 125.
