Which Single Cylinder Bicycle Engine?

[AdvenJack]

Which antique (pre 1920) single cylinder bicycle engine is most available to acquire now,
and get running, to enjoy as a regular use "rider"? E. R. Thomas, Shaw, Harley Davidson,
A. O. Smith Motor wheel, etc.?

Harley did not make a bicycle engine

I don't think any pre-20 bicycle engine is going to be easy or cheap. Might as well whip out the big boy wallet and go hunting for the most complete one you can find. V/r Shawn

For clarification, when I said "Harley-Davidson" and "bicycle engine" in the same sentence,
I did not mean to suggest that H-D was producing motors and advertising them separately
from their own completed motorcycles. I am asking which of all these very early single cylinder
engines are easiest to obtain because their numbers at present are the highest. If I came across
a H-D engine that was a very early single cylinder example, and I had the money to buy it I would.
Same for Indian or whatever brand.

I think this looks pretty much like a bicycle with an engine secured to it.
