Whoa, whoa, WHOA!

Minor correction here:

The synchronizers are still in use!

What you're actually seeing here is that they have alot less mass to accelerate/decelerate.

Weigh the entire rotating assembly, including the clutch/flywheel/pressure plate of the engine (which also produces an opposing force, mind you), versus the armature inside the e-motor. Oh yeah, the synchros can accelerate that little bit of mass with nearly no frictional losses and almost no lever distance very easily.

Basically, try to spin the OEM motor over with your thumb and forefinger on the crank snout. Now do it with an E-motor. Now, you see why you "don't need those synchronizers", right?
