the whole bike life thing in the u.k. is more a mass gathering of stunt/ agro riders on (mostly) unregistered machines being anti social knob heads, speeding, stunting and generally disregarding every other person on the road for rep points.
It's a street man ting innit blud, mans not a dick ed watch man wheelie blud.
It's slowing down a bit now and starting to get a bit more organised since the media picked up on them, the more well known "stunters" are cashing in starting "stunt classes" for younger riders at £25 an hour and trying to make "bike life" a brand selling clothing and hats and stuff, so they don't want the bad press as much.
The younger ones do the same on their push bikes mobbing around acting like cnuts. (edited)
