The buses appear to be made by Blue Bird with an ideal range of either 120 miles or 150 miles.
During the rare cold snaps in which the high here is in the teens, I've tested our EV. So-called "fast" charging is way slow (a normal 10-15 minute charge took over 45 minutes). Not a problem for daily driving because home charging handles daily driving anyway; I just wanted to test what long trip charging would be like in bitter cold. And instead of getting 3.9 miles/kWh on average I got about 2.8 miles/kWh (normal local speed driving). So there are some real issues with charging speed and range in bitter cold. But, again, those are for long trips and not local daily driving.
