I have always had bad experience with jumping bikes since I was a kid. I always fuck up the landing and wipe out... I have been road biking for a while now and really want to take up some rough trails this time, but not without advice.
Learn to bunny hop and manual. First try very small jumps and when you go on it pull back and lean back not too far but enough to level the bike out.when you feel confident try bigger jumps. And no matter what WEAR A HELMET AND KNEE PADS!!!!!!!!!!!!
