For Rabobank Be-A-Muze got together with mannen van staal and created this street campaign. Everybody knows the old school way of making your bike sound like a motorcycle.
You just flip a card and take some tape or a clothespin and off you go.
So when the Rabobank decided to give away bicycles to students. We figured that it would be cool to get the students attention by flipping a bankcard between the spokes for an old school motorcycle sound. That way driving home on your bike you'd feel a bit nostalgic and you'd be informed about the rabobank incentive to hand out bicycles.
On the way out of town you'd be reminded by pretty girls with flyers. :)
