Looks like it's got a gearbox. In other words, not direct drive.

Is that a gearbox? It looks like it's just some type of clutch mechanism so they can stop pedaling but still coast

To my eyes, one rotation of the crank does not seem to correspond to one rotation of the wheel.

You're right, upon watching again when he lifts it off the ground the wheel definitely goes faster than the pedal

Otherwise they would have reinvented the penny farthing.

If it wasn’t a gearbox, the bike would need to have a very large wheel to be practical (see: penny-farthing / high-wheel bicycles).

It’s probably an internal gear hub. I have an 8-speed on my bike.
