It's an approach situated on numerous presumptions about bicycles and a lot of ignorance about them and basic mechanical/electrical engineering principles.
They are proposing a complex electromechanical system with an entire second motor and geartrain to replace a chain and two cogs because they see that setup as "heavy".
They're completely unaware that generators (and especially accompanying gearset, and its power rectification/control circuitry) have substantial losses. Two cogs and a chain are over 95% efficient.
A generator/motor hybrid bicycle would be heavier, have less range, and both mechanically and electrically much more complex. It could not possibly be cheaper.
The blog post is what happens when someone who considers themselves very smart looks at something they know nothing about and says "I know how to fix this."
