Granted, almost none exist yet even though the spec is four years old, I know of one 180W charger and a handful of 240W rated cables, but the possibility is there.
And while 36V & 48V are the most common ebike batteries, they go up to 92 volts for the “not sure how this isn’t just an electric motocycle” ones (Surron etc).
USB-PD 3.1 can go up to 48V 5A for a 240W output.
