The Hopworksfiets party bike was built in, where else, bike- and beer-mad Portland, Oregon, by the bike builders Metrofiets. All you really need to know in order to fall in love with this bike is that it carries not one, but two beer kegs along with a pair of taps to serve the suds.

The mobile bar, a custom build for Portland-based Hopworks Urban Brewery, is a long-wheelbase cargo bike with the load bed up front, which we guess means that pedestrians can’t sneak a quick pint when you’re stopped at the lights. There’s a “sound pannier” at the back, containing an amp and a speaker, and the rear rack is just the right size to carry a stack of pizza boxes.

This party is entirely human-powered, with the help of nine gears — any more would allow a rider to go faster than would be entirely wise, explained Ross. Sturdy looking disc brakes and chunky tires with full fenders adorn both wheels.

When fully loaded with pizza, beer, and ice, the bike should just about meet Metrofiets’ 400lb weight limit. Still, Ross is recommending that the bike be transported with pony kegs, and refilled with full-sized kegs on the scene.

The bike is a group effort. Ross and Nichols designed and built the bike. Damon Eckhoff inspired the sound system and did much of the wiring. Metropolis Cycles (2249 N Williams) built the wheels and provided general bike shop support. Michael Moscarelli of local brewing supply company F.H. Steinbarts did the beer plumbing; local high school biology teacher, homebrewer, and woodworker Gregg Heppner created the bar top and sound system shell. The bike’s components (including the tap handles) were donated by Chris King Components and Shimano.
