Thanks for a quick answear all of you. I've taken a quick descision and bought the Genesis bike The Kona only comes in a 54 size, and it may be a little bit to small for me.

The Genesis looks nice, have the type of handle bar I like, 'vw addict' say it seems to have the best components (together with the Kona), and it's almost on 500$ discount.
I think I will gonna like the bike!
Thanks again for your help.
