A hubless BMX and a helpless designer

I just received an email from Nikolay Boltachev, a beginning graphic designer from Russia. He has been working on a concept for a BMX bicycle with hubless wheels - and it's starting to look pretty great!

However, to take the next step in his project, Nikolay is now urgently looking for more information about hubless wheels and/or magnetic bearings.

Perhaps any of you have been working on a similar project, and have gained some knowledge about this topic?

If you do, please share it via the comments, and gain some major karma points!
