5. How to find suitable hub motor

To customized a suitable motor, could you pls. inform below points: 

  • 1.E-scooter, E-tricycle or E-car, tire model? 
  • 2.Volt and wattage of motor, Speed(kV), and torque/climb angle ?  
  • 3.Your vehicle weight and loading weight?  
  • 4.Lithium or lead-acid Battery?  

We could suggest most suitable motor accordingly, thank you for your cooperation. 

PS. To calculate the speed, v(km/h)=n(r/min)*2rπ(m)*60/1000,   n=load RPM, r=tire radius.

For speed less than 100KPH, consider the Windage Resistance & Rolling resistance.

the load RPM is appr 0.9 * no-load RPM. v(km/h)=0.9*n(r/min)*2rπ(m)*60/1000    

For over 100KPH,  V=0.85*RPM*2rπ*60/1000   


6. Electric Scooter/Motorcycle Hub Motor Conversion Kits List

After confirming the motor, we could try to offer suitable motor kits. 

e.g. Motor Controller, Wheel RIM, charger, speedometer, throttle, brake, DC-DC converter, etc.
