I may have found it. The other day I stumbled across The Cyclery in Ottawa while I was looking for Sheldon Brown's Cyclery on the web. They have a custom built commuter they call the Krike. Shimano 4, 7 or 8 speed Nexus hub with roller brake and a Shimano generator hub, wide slicks, fenders and a rack. I took one for a ride on saturday and I'm very impressed. Superb shifting and stopping, stable and comfortable. My only caveat is that I found the one-size frame a tad short, but there's a tall seat post.
