Software marketer Rick Wilson has maneuvered his three-wheeled, 800-pound Dutch-made Bakfiets cargo bike to three of the Portland farmers markets each week since last spring. Once he sets “Cafe Vélo’s” emergency brake, which, considering the bike’s weight, actually resembles a car hand brake, Wilson unfolds the contraption to reveal a zinc-capped bar topped with porcelain filters that he uses to brew up to seven cups of coffee simultaneously on his handmade drip stand. For $2.50, you get a cup of Stumptown single-origin coffee, ground to order and brewed while you wait. There’s nothing else like it in the city. 8:30 am-2 pm Saturdays at the Portland Farmers Market at Portland State University.
