how to get over my fear !?

you know, if you are that scared of hurting your ass, you can just stuff your pants with some t-shirts to cushin the blow.
and if you wreck, you wreck. pain is just weakness leaving the body.
 
As many have said...practice makes perfect. But you need a good working backbrake to be doing wheelies. Just work on finding the balance point at slow speeds, and work on throttle control and braking. Once u get that down its just working on how far u can ride one out.
 
you dont need back brakes to do a wheelie, you can always pull the clutch in if you feel the quad start to tip back.
 
lol i hav crashed while wheelin twice once on tar lol i fell on my knees blood everyware then the other on grass i fell off while weelin and it drove itsel about 20 feet and tipled into a 3/4 ft deep ditch all i could do was laugh lol
 
well, don't wheelie on the road till u lear to ride, haha, why the heck do u fall off when u screw up, just ride it thru......... learn to balance it by standing on the grabber with ur left foot ( yes i know it looks gay) and putting it in 1st, and keep ur right foot on the brake, pop it up in 1st and go really slow, if it goes too far back, pull in the clutch and tap the brake, and let the clutch out, and keep doin that, i will help u learn to balance
 
oh, also, if u ever snap the grabber, pull urself forward quick, cause the grabber hittin u in the butt reaaaaalllllllly hurts, and bruises tailbones
