Interesting frame design, I like the additional bracing. I wouldn't mind seeing it without all the gear to get a better look at the rear brake caliper. I imagine the lack of a seat tube causes more flex making for a more compliant ride perhaps? The FD looks weird though being that far back from the cranskset and rings. Curious, very curious.
I don't know why,... it's just MUSS easier to pedal than the other ones.
