It's not V2G(Grid) it's V2H(Home).
You would need to have your house setup wired like it needs to be for a Tesla Wall unit.
The bike has a 6.6kw inverter.
The one video I watched on the early Tesla Walls showed you could only use it while the grid power was on.
They later had to install a safety cut off to keep linemen from getting zapped when they think the line is dead so you could use it as backup power during storms and such.
