what can i do to land these out of such a small kicker?

 u need to try and jump ur actual body higher and further ur bike is fine but u chickenin out and landen your feet to short it maybe scary at first to actauly let urself jump wiv the bike but u gotta get ur feet up more and twist those arms

 i sorta had the same problem like 2 years ago, i ain being mean when i say this its just crititism. but your riding above your skill level. that being said i'll tell you right now you gotta really pop up, keep your shoulders over your bars kick quick but not hard and spin with your arms. and reeeallly commit to landing on the pedals. but its gunna be weird to do for you becuase like i said earlier your riding above your skill level. then agian i did see a few guys land hop whips who barely even ride, hellaofalota prac

 your never gonna land it unless the bike stays under you try them on somthing like a qaurter at the skate park but make sure to keep the bike under you and pump with your arms to get it to spin faster.

 when your back tire is infront of you, throw your bars downward i think XD

 its do-able try a tad more speed pull up on the bars and unweight the bike might give you a bit more time to complete the rotation.

 your helicoopering hold it underyou and kick it harder therefore making it soin faster.. good luck

 you need more air to do it your first time it took me about 2 weeks in a foam pit.

 kick it hard with your back foot and follow through,push the bars beside you a little and tuck your legs in

 try puting a small lip on the lende it will help
