5v is what I’ve used

Yes there are stand alone digital temperature gauges that will work with any of my motors. Two XXLs will move a 1500 lb car, but with 50 HP and 100 ft lbs combined performance will be modest. A gearbox would effectively double the power of the motors. That combo would be more fun. Or four XXLs. 😊

39 mph @ 16S with 7:1

TBH I’ve never seen a 105T 219. The largest I’ve found are 96T. The diameter of a 120T 219 is 11.7” by the way. The 24F Nucular is plenty of controller. You might be okay at 7:1 considering how light your bike is. Top speed will be around 55 mph @ 20S.

If you get a good controller and battery that can feed it 10kW the Big Block will wake that LMX right up. Reduction should also be about 8:1. I’m not sure what they run.

Thanks for the suggestion. I don’t sell controllers. People are free to use any controller they want. This customer wanted the ASI and wasn’t concerned with the price.

Motor power has continually increased over the ten years that I’ve been designing and building mid drives. We’re presently at 18kW. Definitely motorcycle power. Here’s a video of a newly completed Motoped build with my largest motor, the XXL, and a High Voltage tuned ASI BAC8000 controller...

Very kind of you and much appreciated. I keep doing this work because I love it. Merry Christmas and Happy Holidays!

I am imagining it. 😁

Here is the dyno sheet on the XXL, kindly provided by Greg at High Voltage Kits. The kv of the XXL is 62 rpm/volt, the same as the XL and Big Block. The Small Block is the exception with a kv of 67 rpm/volt. I use the highest kv available from the factory. I tried the lower kv motors and noticed...

Chances are very good that you’ll get to see an example. I have a nice ‘66 Honda Sport 90 that I plan to put this combination on. Dyno tests have shown that the XXL puts out 50 ft lbs and 18kW. Vad’s NextGen should push even more watts through the XXL thanks to higher voltage. Since my S90 had...

Thanks for the corrections Vad. I’ve heard that FOC does great things with IPM motors. This should be a match made in Heaven. I appreciate your excellent support and hands on expertise Vad.

High Voltage Kits produces complete plug and play ASI controller kits for my motors. The ASI controllers are very advanced but are notoriously difficult to set up properly. Greg at HV has dyno tuned the ASIs to run perfectly and made a dedicated wire loom. (greg@highvoltagekits.com) A new...

The important feature is the internal magnets. My original motors had external magnets that would come loose above 7,000 rpm. The SurRon motors have the same issue. The new IPM motors have the magnets buried in the rotor.
