The Brad, kids bike/handgrab scene from Goonies is also a favourite.

Then there’s also the wheel change scene in American Flyers by Rae-Dawn Chong !!
YouTube - SCREEN GODDESSES: Rae Dawn Chong makes herself useful
Its probably cheating but this TV footage was used in Amelie, and its pretty amazing:
YouTube - Horse Wanted To Be Part Of The Bike Race
But this ain’t cheating and this would have to be the best scene, surely?!:
YouTube - Bicycle thief Last Scene

“And she’s okay!”

Their was that TopGear ep where they raced a car against pair of BMXers.
The bmx bicycle/kung fu fighting scene in ‘Lady is the Boss’. This scene used to be available on YouTube - but it’s been removed for copyright reasons. In the scene, Kara Hui and some other girls fight off some thugs using BMX bikes and kung fu. See The Lady is the Boss (1983) . As far as I’m aware the rest of the movie (apart from that scene) is shite.
Bumppppp bandits
Really should restore my Malvern star Supermax…
Jason Statham BMX scene in Transporter 3. 10+ on the implaus-o-meter.
