WhatcomRider nails it. Xtracycle now has made the collaboration with Justin and Sam Whittingham (of Naked Bicycles) official: part 1
; part 2
. It looks like the production model is going to be called the EdgeRunner--but they're calling it a "series", so maybe more than one model?
Looks like an exciting product. The devil is in the details, but with guys like Justin and Sam involved, the details should get a lot of loving attention. Many here will appreciate the 20" rear wheel. Based what he said during the Ebike Nerdcast interview, Justin is focused on sub-30mph, practical and highly reliable
transportation, because that's where the potential for social transformation is. But he's obviously sympathetic to hobbiests and hot-rodders, so this could be a really interesting (that is, hackable) platform. The "mule" prototype frame is absolutely gorgeous.
