What is a kickflip? A Kickflip starts with an Ollie, but you flick the board with your foot to make it spin underneath you while in the air. In a clean kickflip, the skater kicks the board with the top and side of his or her front foot, the skateboard flips and spins over at least once, and the skateboarder lands on the skateboard comfortably, wheels down, and rides away. You can read more about the definition of Kickflip and who invented it in the Skateboarding Dictionary.
If you are brand new to skateboarding, you'll first need to learn to ollie before learning to kickflip (read How to Ollie). Plus, you may want to take some time getting used to riding your skateboard (read Just Starting Out Skateboarding) before learning to ollie or kickflip. Of course, it is totally up to you – if you are aggressive and want to learn to kickflip on your skateboard before learning how to ride, that’s up to you!
Make sure you read all of these instructions before you try to kickflip. Once you are familiar with them, go for it! Also, watch this Video on How to Kickflip to get an even better idea.
