Let's take a brief look at the winding inside our CZJB electric bike hub motor!
The number of turns of the copper wire is unique, and the hub motor rotating speed of e-bike hub motors is also unique.The differernt speed according electric bike rim.Differernt e-bike rim has differernt motor speed.
Calculation formula:load speed/4785/wheel size*1000000=motor rotating speed
For example,our e-bike hub motor speed is 25km/h,now we calculate motor rotating speed
1.wheel size is 26":25/4785/26*1000000=200RPM
2.200RPM: 200/1000000*4785*26=25km/h(load speed),if no load speed,add 30rpm.
