It's the Conference Bike.
The "driver" sits in the back; he and 6 "stokers" are in a circle facing each other. Each can choose whether to assist with locomotion.
Will we be seeing these in bike lanes, and on the Greenbelt, soon?
It's billed as a "party on wheels." A "corporate team-builder." (GAG! They need a little donut-and-coffee table in the middle there...)
