Heh--I have a Locomotief Populaire, bought from Jan Rekers Tweewheelers in Hoensbroek, NL with many thousands of miles on it.
Drum brakes, Sturmy-Archer three-speed gears and heavy as a locomotive. It's a complete nightmare to pedal up the California hills, but I still love it. The chain is completely enclosed and that same chain is nearly 40 years old now.
Opafiets are made to last.
