Newb question bmi engine mount kit

I think that engine mount is for go-karts, not bicycles.

I think the appeal of that item is that it also provides a place and hardware to mount the jackshaft. It would take some major cutting before that would fit most bicycle frames.
I would use a more conventional mounting plate for Briggs style engines and possibly modify and use the bmikarts kit to mount the jackshaft.

You can use it to make a scooter into a bicycle.
