The Backside or Frontside Flip: Difficulty [5/10] Also See (Ollie, Kickflip, Frontside, Backside)
1. Kickflip position
2. Start a 90º ollie and start your kickflip
3. Catch your kickflip at that 90º angle in the air (Now you've done a 90 Flip, you stop here and pull to a grind, or something else, or continue)
4. Use your arms in the air to help you spin that last late 90º to complete the trick.
Why catch the kickflip at a 90º, so you don't over rotate on a full 180º spin.
