Shredder motor – alternative

I saw someone shared how they’d connected a bicycle to their shredder machine instead of a motor… does anyone have any thoughts on whether creating some kind of hand crank would work? Am I being utterly naive? Just thinking in terms of the speed needing to be slow – unsure about the power, and whether a series of gears could then make it feasible?

Thoughts?

Yes, using a hand crank is feasible, you just need to use the right set of gears to convert your hand power to torque.
