I would just like to point out that 160lbs isn't that heavy for a human.
Sure, if she had 100lbs on you, I'd understand, but really, now.

The basketball team found the scooters lying about during one summer practice. We ended up playing some lacrosse-like-type game on them. It was amazing. ^^
We, didn't use our hands, really. Well, we did for a few minutes. After several of us started bleeding we stopped that. Too, about that time we found we could go much faster using our legs. And it made things much more interesting, since you were going backwards, could go faster, and be lazier. . . . and. . well. . .we're a rather violent group, it was awesome.
