The Tor version of Openbazaar is available as of a few days ago. You can download it here.

At this point it is stable and can be used to run a store via Tor. The last of the core system (arbitration and notary) will be completed by the end of the year.
I am not a fan of it. You will go faster walking the bike than pedaling due to cogging so those pedals are mostly for show (or stealth.) And the $10,000 pricetag is just crazy, you could buy an electric zero fx for that. For reasonably fast speeds I would go with a kit like this from em3ev

Select the largest battery and fastest speed option, pop that onto a hardtail MTB from craigslist and you've got a fast ebike with the same range for about $1700. Plus this is a geared motor so you don't have any drag from cogging, it just freewheels which makes pedaling and coasting much more fun.
The kind of ebike you're recommending is called a mid drive, not a direct drive. Mid drives connect to the bike chain so it combines your bike's gears with the motor, that's where all that great hill climbing ability comes from.
Direct drive is just a regular hub type that sits in the center of the wheel. They're not so good since they do not use the bike's gears, you end up with cogging when pedaling, it distributes the bike's weight unevenly and low power restrictions make it fairly useless for hills. There's also geared hubs these days which look similar but work a little better.
Course, any of these types are better than the copenhagen wheel.
Personally my dream ebike would be a Bosch mid drive connected to a nuvinci internal shifting hub via a gates carbon drive, all mounted on a full suspension carbon fiber frame with the battery mounted in the center triangle.
