dude holy shit I applied this tip during a my sesh tonight and I'm fucking flipping it so easy! I actually almost teared up how much time I struggled with trying to understand the flick all I fucking needed to do was open up my hip a bit and it feels like it just flicks on its own. You're a fucking legend and hero dude
Bro today i landed 3 in a row! Ive landed a few rocketed but the hip and knee thing for real just made it comfortable landed 3 that was pretty leveled out!!!!
that flip in the intro with hands in pocket is the type of skating I aspire to do.
i always tell beginners to think that they are kickflipping with their knee, not their feet and that somehow usually works, (leading with your knee forward of your nose)
this is a great analogy
Damn I’m gonna try this tomorrow
Im gonna try this today. Tho my previous attempts it did feel like the knee is the one in control most often. Even in ollies I feel the same way
ankle does a lot of the work, don't sleep on ankle
Your channel got me back into skating after over 2 decades
i owe this man my life he actually taught me how to do a kickflip I haven't been able to land a kickflip in 5 years since I started I've never learned how to do a kickflip thank you so muchsubscribing rn I'm so happy man thank you you don't understand how happy I am I feel so accomplished thanks to this man thank you again I'm not even sure if you'll see my comment but just know your the reason i landed my first kickflip
Thanks for the comment. My video wouldn’t have been anything without your effort.
Congrats!
this video was by far the biggest asset to being able to land my first kickflip. tysm!
Thank you! After years of failed attempts I can now kickflip 9/10 tries. ❤❤❤
Your videos are awesome, learning kickflips rn, this just happened to drop and it's mad helpful
I've landed 4 kickflips and I am struggling progressing. I'm actually regressing lately. I'm guilty of applying wayyy too much force on both the pop and the flick as you stated in your other kickflip video and thanks to you I truly believe I can master them now! 💙
Man your series really helped me so much, ty❤
Amazing can't wait to try
Excellent video as always!
Thank you, it is very interesting!! Nice analysis
THANK YOU! This one really helped me get kickflips more consistently, now I'm doing them up a small euro gap and landing on the bolt! You are always putting out great and helpful content. Love the channel!
I am in love with this channel. Thank you ❤😭
Awesome video as always. I have a few details to work on now. 👍
amazing video. kickflips are so elusice to me. thumbs up for reach. keep going please, one of skateboardings most valuable creators! (seriously)
daaamn man this one so deep as usual!
Sick board dude! 👍
these videos are so high quality its crazy. i dont even skate but they make me kinda want to. really great great job on this channel
Also id just like to add your channel is probably my top favorite these 2 weeks i wish i had came across your channel sooner. Im also reccomending local skatepark goers to your channel. I wish you the best
you and mitchie brusco should collab. for real!!
These videos have awesome explanations, I'm looking forward to working on my knee because it's always my front foot too quickly on the ground. I really wanna land my kickflips. Thank you for this.
good work cant imagine how much time this took
he's so smart🤩
Thank uuuu
gracias, saludos desde argentina
Can you do an analysis on how to Nollie? +10 years in skating, still can't do them unless I'm going very slow...
Physics just became a whole lot more fun to learn about.
Just the wakeup call I needed
i did my first kickflip after watching this video :)
can you make a tutorial on how to kickflip or doing trick in general higher?
Thank you for this. Kickflips are frustrating. I just want to have control and consistency and it’s so difficult. I’m gonna try opening up the knee and see if that helps. Thanks again
2:30 You also need to add the force the nose of the skate is making when rising, so the force you have to employ is for example 502g (from the foot for the rotation) plus the Relative Force that the board is projecting while going up.
want to know some really interesting physics? so the board is balanced, but also with areas of higher mass. when you press down on tail or nose it adds and uneven amount of inertia into the board. the lifted truck has more rotational momentum based inertia, which actually make it physically "heavier" than the other truck. the "lighter" truck then being able to leveraged up using the axis point of the highest mass. which isn't actually in the center and why good flips and ollies are caught with the back foot pointing down. front foot determines lowest height, but back end should be higher and press to the foot
there can be a drag, but the flip comes from flipping through the pocket, which curves over your foot at a certain angle, an to the side of the highest mass of the high mass area i.e. the baseplate. if you flip it before the truck it rockets, on or just past will go kind of even, and extended out will actually get leverage on the axis point and rise to your back foot forcefully. if you do it right, you preserve or redirect some of the rotation based inertia up while still leveraging the flip off the side of the highest mass of the reference frame. hardest part is learning to pick you feet up again. if entropy takes over or you bleed too much inertia, them tricks either don't work or are messed up. it's the basis for tricks like nollie front foot flips i.e. initial leverage to inertia juggle leverage to inertia juggle flip...
Dude you should do one for the heelflip
Uki
So great. Thank you! One idea i had the other day: i would love to see your analysis of truck geometry and how that impacts skating. People only seem to talk about the wheelbase difference of thunder vs Ace, etc, but are the kingpins or pivots at different degrees of angle? If so, how does that affect turning?
Will see what I can do. I guess I’ll be customizing the physics simulator I developed a while ago.

Im always so back and forth with my flips. Ive got kickflips one day and heels the next.
@whythetrick are you ever gonna do one for heel flips?
On it!
please do heelflip next! thank you for this vid
Working on it!
@@whythetrick you're awesome! thanks so much
Lead with that knee. Delay that flick slightly
I would luv to see an analisis of Luan Oliveira's legendary kickflips from u. Despite of this idea, ty again for sharing your wisdom!
This video actually provides a lot of insight into Luan Oliveira's kickflips already. I was watching Luan's art of the kickflip video, and Luan does kickflips exactly how whythetrick explains them here (as do most people), EXCEPT Luan's board slightly rotates in the air which is the exact result of what is shown here at 4:39 regarding closed knees.
This is really interesting though because Luan does open up his knees like whythetrick suggests, but Luan still likes to extend his lower leg regardless causing the board to spin slightly.
It seems like a style choice, or comfort choice, because it doesn't seem to actually make the flick any better than not extending the lower leg since Luan does it so late into the flick.
@@Lxwlife Ty vm for the awenser! As a brazilian skater and I'm a bit older than Luan I can virtually guarantee this is a stile choice, we brazilians consider stile as: speed + high pop + catch the trick before land. Luan is a god at those 3 stuff. And he intentionally make it looks like a dragonflying kick!
this series is helping me a lot, ehn why the trick heelflip?
heelflip is instead a kickflip on the other side of the board, dont think of using your heel to flip it, but the "back" of your pinky toe
I'm gonna try that opening knee/hip thing, I was only opening my shoulders/upper body.
This trick tip is the best kickflip tip on youtube. Watched many videos they never mention this.
Do you open your knee the same way with a heelflip or how does it work?
working on it. please wait.
Lately I’ve been wondering why no one talks about the crouch in kickflip. It seems like it should be important yet I’m not sure if I know what is best practice. I see some pros squeezing their knees together when they crouch and others skew the knees in odd ways.
Thanks for the comment. Knee angles when crouched largely depneds on the stiffness of their ankles. Kindly refer to this if interested.

@@whythetrick thanks! I haven’t seen that one yet.
these vids are the best explanations! one day i will do one when someone yells 'do a kickflip' ..one day
looks like your back foot toe is hanging off possibly adding to a more pressure flip-ish scoop. You might find a little more snap on the tail if you don't hang off your toe too much. You can counter balance that change by hanging your weight over your back knee more when you load so that you're not falling backward. Not a pro like you, just something I've been messing with recently.
What I don’t understand is how my shoulders and hips are square to the board and it turns, yet your shoulders are completely open, almost perpendicular to the board yet it still flops straight
I think I'm going to give up on skateboarding...
I'm trying to do a straight kickflip, but it always turns into a kind of backside flip (Angled). I've watched all your videos about the kickflip, but I can't understand why my kickflips are turning into backside flips. When I try, it doesn't seem like before when I used to land them; sometimes it does a Hospital Flip but it's probably because of my tired foot.
I don't know what else to do.
If you could send me a video, I might be able to help you.
@@whythetrick I think I solved the problem, but thanks anyway 😊
fucking genius
Request: How to manual?
Sorry its actually my 2nd request but ive been skating 10 years and i have no idea how to manual longer for 5 seconds lol
Thank you for the comment. Please let me ask you something.
I could always talk about manual tricks but I also don't want to end up saying "Just practice."
What challenge/s are you facing? Perhaps I could help you.
Waiting for the heelflip
Working on it. Please give me some more time!
