Apparently a bicycle built for two just wouldn't do.

Fleets of "pedal buses" that seat up to nine will descend on Charlotte and Tampa ahead of the DNC and RNC, offering delegates, media and assorted hangers-on the opportunity to hob-nob while they ride around town.

Health company Humana is providing 20 of the bike buses in each city. (Tampa's convention is August 27-30; Charlotte's event is September 3-6.) The company says that in addition to helping visitors skirt traffic jams, the super-surreys will "track [passengers'] calories burned, carbon offset and miles ridden."

The buses won't be the only pedal-powered option available. Charlotte has launched its B-Cycle program, reports The New York Times, with 200 bikes available at 20 centrally-located stations.

Meanwhile, here's another look at the bike buses, which Humana hopes will make a splash on Twitter: Renderings show the hashtag #Freewheelin on the side of the vehicles.
