Here is the superimposed comparison of the Revelo with the K3 16. It seems the K3 16 has a slightly longer chainstay, maybe 20-30mm. The distance between the BB and front axle seems to be the same. BB on K3 16 is maybe 10mm higher from the ground. The seat tube angle looks the same. Fork on the Revelo seems to be sloped back more with the handlebar further forward, I don't know what this does to steering.
The benefit of the K3 16 is disc brakes, smaller fold. Probably 135mm dropout so you might have an easier time with chainline if you want to install FD. Bad thing is symmetric/double parallel spoke holes on the rim that supposedly will eventually crack.
The benefit of the Revelo seems to be more stiff seatpost and stem, adjustable height handlebar post, ability to add front rack that might fit full sized panniers, possibly fit wider tires.
However, this is all assuming they're both using the same diameter wheels. Who knows whether they're 305 or 349mm.
