Crazy legs I think I speak for a lot of people when I say, do that again, please!
On a serious note, when I first started biking back in the day I would go along at a good speed then jam the front brake on. I would then learn to jump over the bars onto my feet and also how to land without injuring myself.
It might not be a bad idea to learn how to do that, get an old bike not a new one and practice jumping over the bars, sound stupid but it is a skill that everyone should have, as sooner or later chances are we are all going over the bars
Some of us will have our heads go one way and our bodies the other while we attempt to plant our faces into the ground, some of us will not
That said if I do I will come back and show everyone the picture!
