1920’s Steffey Motor

[New Mexico Brant]

Here is a bonafide Steffey two stroke bicycle engine from the 1920’s. My plan it to do a built with a skirted fender motorbike frame. I still haven't chosen which to use yet. It maybe one of the only Steffey builds in history not referred to as a 1901!

In early 20th century motoring literature Steffey is repeatedly cited as the first American builder of motorcycle engines. They were producing clamp-on motors from 1900 through 1928 (and possibly longer).

Note you could send Steffey a drawing (paper pattern) of your frame and they would custom build a tank. That is the plan for this build.

From a 1905 trade journal:

I am thinking one of these. If the Excelsior I will to plan an alternative fuel tank.

Those skirted fenders would look great on a Steffey build!

Leave the Excelsior alone. It's too nice. Use the one with no tank.

 

[Barto]

Is that the correct tank? Not a great fit up front!

 

[Wilfredo]

I will live the exelcior alone for now, after you finish with the adapting, then move all to the Exelcior.

I concur with the sentiment regarding the Excelsior. Leave it alone. Looks too cool. I had a couple of Steffey motors that I bought from Alan Sherman at the Iron Ranch. I should have built something out of them, but they went byebye in a trade.

It will be really cool to see this build...

Do you have any Steffey or Shaw engines you would part with? Looking for a project engine. -Austin (802) 272-2407
