This is the bike I commute on about half the time (I have a foldie I really like). It's an old Schwinn something or other. I built the 700c wheels with Sturmey Archer hubs; the rear is anRXL-RD5 5 speed, the front is an X-FD. Both are drum brakes. 44 tooth Sturmey Archer chainring. I've added a Dymotec bottle generator which I'm really happy with. Double leg kickstand so it stands up like a boss. I have a frame lock on the rear that's super convenient for quick runs into a cafe or whatever.
