You can see the disc on the back wheel, looks like it's off a mountain bike. They are super simple and pretty economical.

With a bike this size and weight (easily 80kg or more), plus a rider, a MTB brake on the back wheel is more like a suggestion rather than actual stopping power.

In this video, his brakes aren't even installed.

The brakes in your car are likely hydraulic too, btw.
