I don't understand how this has any meaning without the power data like Xter provided = volts & amps.

How do you measure "no load?"

Al

Lift the wheel off the ground and have a calibrated speedo on the wheel.

The amount of 'drop' gives an idication of how much load is on the motor.

408 Crystalyte brushless

No load - 31.3 mph
Top Speed - 26.6 mph
Loss 4.7 mph

At what voltage?


As for mine

408 Crystalyte, but from a 408/4012 center tapped motor
48V
No load - 29.1 mph
Top Speed 22.7 mph
Loss 6.4 mph

Interesting if you're on 48V. As I suspected, the 408's aren't the same.

At what voltage?

50.4 volts. (Boost Pack included)

That's interesting. My 48V 40A 5303 front hub on a 28" wheel goes 54 mph no load, and usually around 33.5 mph on flat ground. Shows the difference the extra torque makes, as you reached 82% no-load speed while I was at 62%. But considering you're using the higher-winding motor, and smaller wheels, and more power, it doesn't seem like that big a difference. I wonder what you'd get with a 5303, all else equal.

Gross weight is about 420#, so each motor is pulling about 140#

I know this is not typical as there is something not wright

No load = 48V 35A 406, draw = 0.7A @ 61.5kmh
On road = 48V 35A 406 34kmh
