Hips and thighs have problems with bucket seating…Hulk and Rip Ride Rocket. There is a special slightly bigger seat on these if you ask CM but you need to be pretty close in the sample seat. No major problems on others…will have to see about Hagrids
Everything I have read and seen about Hagrid’s indicates that you will have a better chance on the bike if you are a bigger person than you will in the sidecar.
