Looks dangerous!
All I did was click on the site below your video (gearpatrol.com). I'm lazy. Didn't go and do any investigating elsewhere.
really? Cause http://ww2.ktrakcycle.com/ didn't work for me. Although http://www.ktrak.pl/ and http://www.ktrak.es/preguntasfrecuenteseng.htm do work.
I connected to the site...you supply the bike frame and for $529.00 you get the rear drive and track assembly and the front ski.

Cool! This a prototype or are they sold in stores? If it snowed here, I'd have one.
