New York City banned billboard trucks in 2002, (why hasn't every city?) so Ariel Fefer came up with AdBikes, calling it "mobile green advertising. The custom designed AdBike is a quadricycle with a fiberglass pod that contains the ad, as well as lighting, a sound system and a compartment that easily fits premium items and brochures for easy sampling. The AdBike is even equipped with refrigeration, if necessary. "
While what's not to love about putting cycles to work, Roads are for transportation and these things are clogging a limited public resource for advertising, which some might say we have too much of in our cities.
