Highest measured effect i’ve had was about 4years ago on a 24v heinzmann with lipo batteries was 56 AMP at 27-28V giving spinning frontwheel at more than 1kw in and probably more than 700w out

Well there where the expensive Heinzmann motors, of which i’ve owned a few.
They’re monster strong, geared DC motors, only floor is that the brushes tend to hang after some years of use.
Danish postalservice uses them extensively

Any news on the 500w motor?
Any one in here knowing if the motors for eg 20" is geared different than for a 26" wheel, or is the motor af a different kV?
