It's not free in a bicycle - it requires significant design compromises in the drivetrain because normally the rear hub has a freewheel to keep it from being back-driven (this may be part of the reason they went for "pedal-by-wire").

On a vehicle like this, which resembles a bicycle but is not one, it's free to implement regenerative braking. It already has all of the necessary components.
