I saw several different Kalkoff models in the flesh when I was up in Nantes for Christmas. Very nice bikes, great looking build quality but I have read too many scary things about the motors breaking recently.
The bars, flat bars are not very comfortable if you have a hilly ride. At the very least you would need to put some bar ends on so that you can get down flat in your downhill sections.
The Giant road e+1 I have seen also, very sexy bike.
