It's the first time I have seen a rumble seat on a bike. Very cool.

A warning label on the gas tank: "Do Not Operate sidecar/motorcycle with a passenger in the rumble-seat only. The first passenger belongs in the front seat of the sidecar or the pillon seat of the motorcycle, failure to carry the passenger in this fashion may result in catastrophic loss of control, especially if the passenger is obese."
