Awareness Raising Spoke Cards Campaign Project?

If it helps, i think we could easily over complicate this card, by portraying everyone's idea of correct symbols, drop bars on the bikes etc, etc.
I agree with BDW - i showed my missus the proposed card, without any explanations, and her response........?
"Shit, that's a good idea. Especially after this incident in London"
God love 'er...
It works.

I mentioned it to mine plus her friends over drinks and i got
"What's a spoke card"
"But wont people thing thats a flyer for some band night or advert for cleaning services?"

Got to hand it to her. the target audience is tight but i think the message is clear enough.
