For transport in The Towns, I use an American 1948 "The World"-bicycle. It has a heavy, fillet-brazed frame, no gears, rear coaster brake and front hub brake.
The front hub is almost certainly retrofitted.
It feels really wonderful, but getting spare parts is not always easy The cable to the front brake (top) isn't supposed to be fastened like that, but what are you going to do. It is also hard to find bike shops willing to open up those hubs and replace the brake shoes.
