Hi Lawrence, Chris and All,
Motor eff is variable. Motor are not eff at low rpm, hub or
otherwise. Series like we use are about 82% peak, most PM's about 90% eff
peak. Specially made larger dia versions can be more eff but pricey.
Chris' comments on hub motors is correct especi

When I saw the Stella it made growling ticking noises that stopped after the
vehicle made some speed. They said these motors were 98 % efficient. I
thought the run of the mill ADC motor with a Curtis controller was 90 % and
brushless were a bit more efficient. Are these motors worth the 10's
