· Buying guides - 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

· Electric Bike 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.

PS. So far, the battery is not avaiable.
