    it`s happened to me when i turned and bent to the left accidentally very quickly to stop...normally i can stop,but this time by bending i amplified the move,near to fall down...
    yes,i ride an inexpensive mountain bike,full suspension...it matters?
    so i explained myself what was all about
    thank you for the reactions...

    I took that to mean bouncing up and down, like a yo-yo, on a full suspension mountain bike.

    Other than that i have no clue...

    *watches melted brain dribble out of left nostril*

    To the OP, can you give us any more idea of what you are talking about? An example perhaps?

    The only thing I can find about the "yo-yo effect" is to do with dieting.

    I believe the experiment you referenced was how they proved that the gyroscopic effect does not keep a bicycle upright. I think now, it is believed that general frame geometry and inertia are what keep a bike up and rolling in one direction.

    No offense taken.

    Just think when asking a question, if you have given enough detail to get a coherent answer.
