Well, im pretty young and i just got into mtb. ive been riding bikes since i was three and im hella stable and all that stuff and i find trail riding awesome. but after a while it gets old when i cant drive to parks 20 miles away so ive started to get into down hill. the jumps there range from 6 inches to more than eight feet. im doin the 1 foot jumps but am terified of goin off bigger ones because as soon as i go off the jump my bike falls from under me and i lose my foot hold and when i land i bounce up and down several times. Help me out
