Here is something like it, also from a "retired" small company "zipp cycle" roller drive with weeder motor in frame.

Yow! 40 plus on a bike, not me, fast motor and slow breaks
leads to brokes.

I am having grinding bearing ... sounds coming from my front wheel a 25.

I have to say the one friction kit like really like was one I can't remember the name of.
Was a mid frame engine mount with the roller contacting wheel right behind the engine. looked balanced and sharp
