Welcome, from SE Wisconsin, USA!
That looks like an eFatty; I just got one myself. They're not very nice to pedal uphill unpowered nor too efficient on pavement, but they'll roll over quite a lot, and you have a huge range of options of tire pressures. 5-8 PSI for rugged trails or really loose surfaces. 15 PSI for a compromise between ride quality and efficiency, 20 PSI for getting the most range out of the battery on pavement.
All the best!
