Bike builders, Metrofiets in Portland, Oregon have not only designed but built THE party bike. Named the Hopworksfiets party bike it was built for the Hopworks Urban Brewery. It holds two kegs with beer taps, has a wood inlaid bar, pizza carrier, and it's own sound system. Super dope... but also weighs 400 pounds! Hope you have some seriously strong legs!!!
