Here are some photos of the Dietz 1910 Runabout... which was really a half-scale replica built in the late 1970s. The particular gas one being converted to electric was built by my Dad's company, The Henry G. Dietz Co. Inc., in 1977. I (professor Dietz) was personally deeply involved in creating these cars.
The idea to make this really began with my pinewood derby entry one year in Cub Scouts:
I later built a soapbox derby entry that looked just like it, and that drew lots of press attention. Here are some photos of it from back in the day...
Those were as soon as I had completed building the car, and before the race (with the paint still wet). My brother, Paul, actually drove the car in the race:
We didn't win on speed, but did win for "Best Construction."
