some of the bikes are very interesting as the jamis, but the one i like the most is the kona paddy 3 with sturmey archer, it's beautiful too. sadly not easy to see one in europe.
i like disk brakes on mtb, they are aggressive, but on my commuter i have drum brakes and they work really well and are almost indestructable. on a city bike i would also choose v-brakes.
i reached this conclusion after my cooleague bought a fuji with disks, the pads don't last too long enough in my opinion.
but the fuji is a really good bike compared to what you see in shops here, i looked in the company site and saw the verion with nexus 8, and also some nice models with cro-moly frames.
