Larger motor pulley = more efficient?

@rafaelinmissouri shared some interesting findings here The Carver... My final frontier - #210 by rafaelinmissouri

Very surprising that 200mm Kenda tires result in better wh/mile efficiency than 155mm metros. Seems like bigger tires with more rotational mass should be worse on efficiency. I don’t understand it.

I might swap kenda’s onto my TB AT wheels to see if I get the same result.

I’m also coming around to the idea of doing some real world testing / science.

  1. 12t vs 20t motor pulleys
  2. 10mm belts vs 15mm belts

Both tests would involve cruising at 20mph for a couple miles, starting from full battery pack to control for voltage. Anyone have predictions?
