Are you still driving your Sparrow with your butt planted on the seat like a normal guardian? How embarrassing.
Freke Out has simple instructions on how to use your Sparrow like a surfboard instead -- while dancing, no less. It's as simple as timing an interruption of your mounting the Sparrow with a gesture. So you can dance-surf or sit-surf to your heart's content. I'm not sure there's any other way to ride a Sparrow than to dance-surf it from now on. Of course, it does seem to lead to a lot of death, but who cares about that when you're being *fabulous*.
