I think it is more the case of tenagers & grown men on unrego`d bikes, tearing their way up & down suburban streets day after day, where there are heaps of little kids on pushbikes, scooters etc etc
Lets face it, noisy bikes doing that crap in the wrong areas spoil it for all of us!!!
My neighbourhood has a lot of riders, both rego`d & unrego`d & most put up with the bikes as long as they go steady & keep the noise & speed down
I have lived in the same place for the past 20 yrs, ridden there myself & been chased out by Rangers in the past, so now I avoid it 
But, like everything else we do in life,,, It only takes the minority to stuff it up for the rest :unsure:
