Awesome info.
This bike is the coolest thing I've seen in a long time.
Sure discs and single sided wheels are nothing new but the reversed drivetrain!
If this was applied to a 700C bike, you could run a 29t front and 7t rear and you would still get ~111 gear inches like a 12/50T gets you.
A relatively small plastic cover could enclose the drivetrain.
I also think the entire bike might be able to be made more narrow and lighter since the axles are shorter.
The aero and weight advantages could change the road cycling game (if the UCI never existed).
I also love how easy it is to remove the whole chain and clean it.
