How fast are you spinning when it starts to happen? Everyone gets a bit choppy when they get really high. Some people can spin exceptionally fast and smooth (like pros who are known for sprinting ability), but many people start to bounce and get choppy at speeds over 110 -120 rpms or so. I can spin smoothly up to about 130 or so, but I rarely do this anywhere but on the trainer...
