The question about overspeeding came when I suggested a gear driven application which used a lower power lower weight motor coupled to the driveshaft via gear/chain in reduction.

If the max RPM of the motor was 6000 RPM, and it could only propel the vehicle up to 20 MPH at max RPM, anything faster than that (vehicle speed) would overspeed the e-motor due to the resultant gear multiplication.
