If you've ever been to Couleur Café before, you'll have seen and heard these honking cyclists. With a mobile DJ-stage on their bikes they search for the coolest spots on the festival grounds to play the hottest beats. With more than 10 pre-warmed DJs, they pound the ground beneath the Atomium. The Bankra Bike Sound System is a Couleur Café favourite and when you meet them you'll understand why.
