When you're doing Full Cabs there's a couple tricks I can give you. A little bit of advice that'll make your life a little easier.
What you wanna do is, you wanna have your Fakies or your Rollbacks and your Rollouts or Half Cabs dialed. Half Cab is kinda the precursor to doing a Full Cab.
Now, when you're doing a Full Cab you just wanna have a little more force, a little more pull. A Full Cab is to a Half Cab what a 360 is to a 180. So you just gotta kind of double your momentum in the trick itself.
With the Full Cab what I like to do is I like to almost do a little bit of a Rollout at the beginning. I'll go maybe a 90 degrees where I'll roll out a little bit of the ways. And then, as soon as I hit that point, that's when I'm gonna pop. I'm looking the direction I'm spinning. I'm gonna spot my landing, which will be the direction I was facing when I started. You're gonna let your bike come back around underneath you. As soon as you have that space you're gonna level off the bike, land both tires flat, go into your Rollback or your Fakie, and then you can do a couple of Full Cabs if you like or just roll out.
It's a great way to link a couple tricks or just add a little pizzazz if you can do them down stairs or more obstacles.
And that's how you do a Full Cab.
