Here are some links for more specs:

The second link looks weird because it's a cached Google page. The actual page seems to be gone, and the links are broken on the Miele site.

Anyway, I'd go with the Kona if it were me. The Diamondback has the same freewheel as my first bike (a GT Timberline). The lowest gear is so much lower than the second gear that it feels like the chain fell off when you switch to it. A low gear like that is nice, but the Kona probably has a lower combination available since it has a triple crank (as opposed to the single on the Diamondback) and a 32-tooth lowest gear. I also like the EZ Fire shifter better than the twist.

Of course, it looks like the Miele's got these same things going for it, but I don't know anything about Miele, whereas I own a Kona Jake, which I love. I think the tires are better on the Kona. The frame is made of a different type of aluminum, but I'm not sure either one is better than the other.
