thanks all for the good comments!
Keith, here in Brazil I think there are only two original exemplars in São Paulo. Rio de Janeiro I really don't know. The pedal car model is in Curitiba, 500 miles from Rio de Janeiro.
"Dean-Royal", the eletric version, was tested with a battery 250W. It is not exactly a power plant, but the top speed has been almost 22 mph.
"Hans1970", this models are made to adults and kids enjoy.
I'll post new photos soon.
