Humm, the frame material description on the Devinci seems very vage, Alum. frame/cro-mo steel fork is a nice combo, I ride a 2011 Jamis Allegro 1 with that combo, the Devinci seems more like my wife's KHS Vitamin A, fitness bike in style where the KHS Uban Xcape seems more like a "city commuter". IF your just doing commuting and errands with short rides, I'd go with the KHS, "IF" it acutally FITS YOU!! If your looking to maybe get out for some longer recreational riders or overnighters, the Devinci would be my pick, again "IF" it FITS YOU!! If you get a bike that doesn't FIT you, YOU will HATE it, jmho, ymmv. The Devinci only showed XL and XS sizes so I'd want to have them FIT me in person. Good Luck and whatever you choose ENJOY!
