"All the Astro's being used on ebikes are a mistake IMHO. I used to believe. Lots of time dyno'ing various electric motors and building race bikes and burning up motors and re-winding and burning up motors has lead me to believe you're simply never going to get reliable high performance from a motor in a small package, unless your application is driving a prop at a near constant speed right in its efficiency zone"
