The bike does have significance as a symbol of fun but we like it because it is also a useful tool, economical, sustainable. We also see some opportunity to talk about giving families wheels. Or things like "learning to have fun with your family is like riding a bike". We see it as a good metaphor for our message but we think there are other good metaphors. I like the idea of a ball as the logo as well but what I'm really hoping for is a lettermark that could stand alone as the logo.
