I love what they've done with the main pivot going through the frame, reminds me of the sadly now-gone SC Bullit. The FRAME, to me looks burly enough, but those wheels just make me think "flat spots" if ya come up short or go long in the park. Still, I think it ooks like a FUN bike and while it's got some "odd" things going on, I think 99% of it is just the big wheels changing the scale of everything.

 would the structural integrity of this bike be compromised if you were to reduce the fork and wheels to 650b instead of 29 inch?

 Looks funny with the seat that far up on the rails. Nice bike though, I like it a lot.

 Looks kinda of weak..... or is it because the big wheels just dwarf the frame
