Are you asking what I think makes a "beginner"?
I'm sure the dictionary definition is something like, "someone who is new to a sport or activity"
So if there are kids who can hit tailwhips or barspins if they are trying really hard, and if they happened to hit both in the same run that is sick as hell! haha, I'm just saying someone who is new.
anddd, did anyone see any of weeman's first xtreme wheels comp runs? he did alleyoop 180's and some feeble stalls and stuff, i think he was a great example of a beginner. he had been riding maybe 3 months.
