83mm bottom bracket Scott Gambler what size Bafang motor?

Hi guys, real newbie here. I want to add a Bafang 1000 watt motor to my 2008 Scott Gambler and looking at the specs it says it has a 83mm bottom bracket, the bafangs are 68, 100 or 120mm. Any idea on the size I should order?

100mm and get some spacers.

I opted for the fat fat tire at 120mm so i can always switch my BBSHD out to another bike if/when needed.
