Re: The upgrade!! Electra "rat rod" frame mod.
I have a real nice Electra Townie and I was tempted to use it but that long distance between the frame rails really worried me.
If I do anything with it, it may be an Electric front hub motor.
Your motor mount is very inventive but it would really worry me.
Maybe you could weld in another verticle piece from the bottom up to that piece you cut off so you could use the normal rear seat post mount.
You may have been through trying all this already, but good luck and keep us posted to how it works out.
