Big flip or longer Bigspin Flip is a super cool trick that you just need to have in your pocket for every game of skate you play 🙂 It looks very good, it is popular either regular and switch as well as fakie and nollie. Everyone can do it if you only manage to combine the back side Bigspin and a Kick Flip.
As that said, you would think that the basic is to learn backside Bigspins and back side Kick flips first. This can sure help a lot, but it is a lot easier if you imagine how to combine a 360 Flip and a backside 180. This is a combination of tricks that you sure already have so it won’t be too hard to put them together.
Your back foot should be on the pocket same as with 360 flips and your front foot in the Kick flip position. You should pop into 360 flip but at the same time start turning your shoulders into back side rotation, so the body is going with the board. If the pop is strong enough you will catch the board in a varial flip position and then make the rest of the turn with your body. Just make sure you go down centered to roll away clean.
The things you need to avoid are:
If you lean too much to the front, you will probably get into wheel bite, if you lean to the back you will slip on your hip and the board will fly 🙂 If the flick is not strong enough you will probably land in primo.
Other than that I think you are good to go and I am sure you will shoot your Bigspin Flips very soon!
