Dubbed the B1K. 
Sculpted as a race bike, it features some sort of chainless drivetrain, carbon fiber construction and few details on the rest of its design. What appears to be a tension cable or rod from the seat to the head tube likely keeps the bike’s wheels from splitting apart when a rider’s weight is put on it. The beam seat post likely provides some cushioning effect a la Softride of the '90's.
And those "tires"? :shock: Maybe these are just warming blankets until they roll it out to the start line like they do in Formula 1.
