Bike Dude with air

This was taken at Empire Park Skate park at lunch today. I know that the guys who use bikes and not skateboards are called bike dudes because that it what they are called if they dither about taking their turn (Hey bike dude, are you going?). Empire Park is just across the road from Bar Beach which is why the sea is behind him. I have some questions of Bike Dude - why would you want to ride those tiny little bikes, did you steal it from your six year old brother, why are the seats so low and do you know that your underdaks are showing. Bonds I might add after inspection of other images.
