These tiny laser mems projectors are pretty cool. I like the idea of pointing them at the ground from a bike. If you track the bike speed (and maybe steering direction) you could make the projection appear static in relation to the ground, as if your bike illuminates a small patch of a hidden world as you drive past. The simplest fun thing to do with this would be plain text, e.g as folk see you drive by it appears that words are painted on the ground in special paint that only your bike can illuminate: "HACK THE STREETS!
