I try bunny hopping bmx

[@another3997]

You are starting the hop a fraction too early, so your back wheel isn't reaching it's highest point until AFTER it encounters the bar. Start the hop earlier, or approach it a little more slowly. You don't need that much speed to clear the bar, and it gives you more time to judge the take-off point.
