Can I get a layman's interpretation for what you just said. I think you are saying it doesn't have multiple or adjustable gearing...

I don't think the Bolt EV has variable or multiple gears. Unless it had two motors, it needs a differential.
The motor shaft is a tube. The output is on the left end, and it has a reduction gear to a shaft just behind the motor, and then another reduction gear driving the ring gear on the differential. The differential is concentric with the motor - and so the two half shafts that drive the front wheels are also concentric with the motor. The right side half shaft passes
through the motor tube/shaft. So the motor and gear box are centered between the front wheels, and the two half shafts between the u-joints and CV joints are equal length.
Here is a semi-transparent image:
Of the gears they show, I cannot see where this could be variable. The caveat is the portion of the gearbox housing behind the transparent bits.
