dequinox
10 kW
I actually do have one. That's how I'm determining watt hours used. It's like 9 years old and still ticking.!
Not for this purpose--it can't modify the throttle signal based on settings to "alter" (reduce) the current limit of a controller.neptronix said:A turnigy watt meter ( ~$25 ) is a nice ghetto alternative to a cycle analyst.

Once you know the unloaded RPM, you can guesstimate the loaded RPM as around 80% of that...
But with the RPM you can try to match a similar motor on the simulator to use as a stand in for yours when experimenting with the simulator to find a more optimal setup.
Is your controller programmable? You may be able to dial in the throttle or otherwise better tune the controller's reaction to it.dequinox said:The throttle I bought has issues, namely a very narrow range of input. I'm either too slow or full bore. Hard to get any throttle values in between.

Note that the 130X can be used on the left or right, but you have to get the 108X in one version or the other.

Chalo said:Too-tight axle bearings, or a dragging brake pad. In neither case would it make a difference in Wh/mi efficiency, but in both cases it would dramatically increase wear of the affected component.
30% difference in efficiency between your two bikes probably indicates one of two things: either a major difference in aerodynamic qualities (mainly riding position), or a difference in average speed. Motor efficiency and mechanical losses might differ, but not by nearly that large a margin.

I'm not entirely sure it's aero, as I tuck when I go over 25 on both vehicles.
That's true, however I do ride at nearly 30 on both vehicles :lol:Chalo said:Note that moving through air at 28.5 uses 30% more power than it does at 25. It could be as simple as that.
I have both of these throttles on my bike, and I do like the 108X paddle type the most out of the thumb throttles. I was going to add that the affordable non-programable motor controllers like dequinox has and all of the ones I've used are speed controllers. They end up feeling like a very narrow window of adjustment. The motor simulator comparison below has only one difference; a custom voltage based controller vs. a custom torque based controller. Held at 50% throttle, the standard voltage type controller will put out the full 43 pounds of thrust until 10mph, and then start tapering down. The torque based controller (similar to a phaserunner) will put out a continuous 21 pounds of thrust no matter the speed.Chalo said:dequinox said:The throttle I bought has issues, namely a very narrow range of input.

Are you using the Wuxing 130X throttle?
If so, it's pretty abrupt and insensitive. I've gotten much better feel and definition from the Wuxing 108X paddle type throttle:
Note that the 130X can be used on the left or right, but you have to get the 108X in one version or the other.

Love the bike, and have fun!
