I seen these before, they are real easy. Its like you tried to do an airgrab, but on the ground. and they were all almost exactly the same grabs.
Its ok to make a tutorial for something that already exists, but I hate it when some guy takes something that exists and changes the name in order to make a name for them self.
It did have good editing though and well explained. And the names you came up for them were suitable. Bike Wall Grab might catch on. I wouldn't get your hopes up though.
