I only had a chance to check out the first youtube link but I think it's really good!
If ya don't mind a lil criticism tho - the burnout attempts are jus' a touch on the cheesy side... no offense to ya, but it's not that impressive to the uninitiated when they can see ya pickin' up the rear of the bike (tire even leaves the ground sometimes) and there's no visible smoke.
Perhaps a reshoot with a closeup so you can only see the bottom half of the tire? If you try it on smooth concrete you'll be able to do it w/o pickin' up the bike (but ofc not sittin' on it lol) and ya outa get some smoke... for an advertisement I'd sacrifice a tire fosho heh
Granted - it'd still be kinda cheesy, but ppl dig that sorta thing lol
...not that I've ever
done anything like that ofc
