I have an S-10 conversion with the clutch left out, and you certainly
can shift it without the clutch. But the shifts take several seconds as
you wait for the motor to sync up in speed, and the time I spend
coasting, unless planned well in advance to be going down a hill, etc,
can cause cars to ride up on me.
If I were do another conversion, I would probably leave the clutch in,
despite the efficiency hit, just so that you can shift quickly. That way
you could start in 1st and shift to 2nd quickly, instead of using extra
amps to start up (slowly) in 2nd.
I have a DC motor, so I find myself shifting between 2nd and 3rd gear
around 40 MPH. Perhaps with an AC motor that has a larger RPM range you
could get 0-50 which would be fine for all city driving, or even 0-60
MPH in one gear and shifting wouldn't be much of an issue.

Regarding the AC-31 which I have a lot of experience with, the motor already
has a
front bearing. The information you received from the seller of the motor is
false. Do your
conversion but leave out the flywheel and clutch assembly. If you want to
shift, it can be done
without a clutch as long as you are not using regeneration, else you will
have to feather the
accelerator during the shift. NO CLUTCH NEEDED.
