YES, that is a VERY clean looking drive.
If the designer would improve it by:
extending the primary drive down below the rim,
lowering the engine height as far as practical,
including a quality 4 stroke engine as an option,
using either a free wheel or lock-up on the wheel pulley,
and then offer it for sale,
I'll be the next in line to buy one!
One can only hope that this is the beginning of a commercial product that will someday come to market.
