It's a one-piece longtail frame with a 26" front wheel and a 20" rear wheel that is compatible with all of the cool Xtracycle racks and doodads. You can even run it with an electric-assist hub motor. It's as if my baby blue Madsen and my Xtracycle Monkey Bus went off behind the shade tree and, several design revisions later, popped out the most perfect cargobike for me ever. I am officially on the waiting list for a frameset and plan on being one of the first to tell you all about it in "6-8 weeks."
Until then, watch these happy Bay Area urbanites blissfully enjoying their EdgeRunners and pretend they're really riding around beautiful Tacoma, Washington.
