I think the best course of action is to find an cut the antenna or it’s trace on the board (and verify). Sounds a lot easier than it is though.

Also, horse is bigger/more visible to cars, and maybe could be in the street. So you may not have to wait on traffic crossings as much depending on the area.

I still choose e-bike because poo, but what a looney idea, I love it.
