Make room for a low CG engine on a 20" bike.

    Now that we have gathered the data that show why 20" wheels have many advantages why not do this:

    I suggest that a tubular box could be fabricated and welded that would push the rear wheel back and it would make room for a very low mounted engine. The gas tank would be over the rear wheel.

    Can you imagine it?

    Stu - There are e-bike frames that mount the batteries behind the seat tube, pushing the back tire more rearward.
    Such a frame from a dead e-bike would allow you to mount the engine lower.

    what's wrong with a traditional frame mount?


    (please note those aren't my welds, I found the bike in a dumpster)
